Laser Tooth Whitening

Laser Tooth Whitening

You see your boss and he compliments your efforts on the success of last week's presentation with a promotion. Your response? A half-smile. You see your crush down the corridors. She's smiling that come-hither smile. Your response? A sheepish grin.

Surely, you don't want to give those two VIP's a wrong impression, right? But what is really bothering you that you can't smile that widest smile you should be flashing them? It's those far-from immaculate white teeth your mouth is "stuck" with.

Have you ever thought about teeth whitening? No? white teeth is not only for celebrities. Everybody deserves to smile that bright smile propped with white teeth. So, read on for more info on this long dream of yours - achieving a sunnier smile by teeth whitening.

Whiter teeth is not impossible, you only need the moolah and the drive to pursue this teeth whitening endeavor. Fortunately, there are three teeth whitening methods available for you to choose from. These three differ from each other in cost and effectiveness.

One way to accomplish teeth whitening is through the help of over the counter products that ensure a flashier smile. See, this is not so hard an activity. All you need is ask that trusty saleslady to give you those teeth whitening paraphernalia. This dental whitener kit consists of a mouthpiece, a bleaching agent and sometimes an applicator. This is a DIY method that could easily be done at the comforts of your home sweet home. This home teeth whitening is carried out through wearing the mouthpiece, filling it with the bleaching agent and wearing it overnight. Availing a fitted mouthpiece is often recommended since it produces better results. A formula that contains 15% to 16% of carbamide peroxide is said to be the safest and most effective concentration to achieve that sunny smile. But it is important to know that some teeth discolorations are more stubborn than other. So, results may really vary depending on the resistance of your teeth discoloration. This kind of teeth whitening method is the least expensive. Kits may be bought with a budget of under $50.

A recently presented procedure is laser teeth whitening. From being first developed by NASA scientists, it has become the favorite teeth whitening method of dentists. Why did it win the dentists' preference, you ask. Simply because it's lesser time-consuming, two hours will be enough for the treatment and no follow-up treatment is really that necessary. Dentists seek the help of a peroxide solution to breeze through this teeth whitening process. Then the whitening process will be accelerated with the use of laser. 93% is reported to be the satisfaction rate for this procedure. And this is more preferred by those who are not into the overnight-long wearing of the mouthpiece required by the home teeth whitening method. Its results even last the longest compared to other treatments. One major disadvantage of laser teeth whitening is its effect on one's pocket. A procedure like this could cost one to shell out about $1500. What a hefty price, right?

Another resort for whiter teeth is through the professional teeth whitening method. This is a system that requires dentists to create a mold of your teeth. From this mold, a mouth guard is produced to custom-fit your mouth. You will wear this mouth guard for some hours a day in a period of two weeks. A stronger concentration of carbamide peroxide will be used as a filler on your mouth guard. The setback of this system is its risk of teeth and gum sensitivity. But it is relatively lesser expensive than laser teeth whitening.

Zoom Teeth Whitening

Zoom Teeth Whitening

No matter how frequently you brush your teeth, no matter how careful you are when flossing, they will still get yellow after a while. This natural process of teeth loosing their bright white color is aggravated if you are a smoker or if you drink coffee on a regular basis. There are several procedures, such as the Zoom teeth whitening method, that can help your teeth get back to a bright new white in a matter of hours.

Apart from the popular Zoom teeth whitening procedure you can also try several others, however, when making the choice, your dentist should also have some advice for you. In general you can opt for an "at home" whitening method or for the several dental office whitening procedures. The last set of procedures includes the Zoom teeth whitening method – let's see why this procedure is so effective.How does Zoom teeth whitening work?This method consists of a mixture of gel and special light wave treatments. The patient is seated and the dentist uses a retractor to separate the lips from the teeth so that the gel can be applied. A special gel is then applied on all the exterior faces of the teeth. The dentist is careful, at this point, not to let the gel touch the patient’s gums too much, as it may cause irritation or lesions. After the Zoom teeth whitening gel covers the teeth uniformly, the dentist will shine a special bright light on it for about one hour. The special properties of the Zoom teeth whitening gel and the energy produced by the lamp produce chemical reactions that lead to tooth whitening. Although waiting for an hour in the dentist's chair for the gel and light waves to take effect might sound boring, it is one of the best tooth whitening methods available today.

How long does it last and what effects can I expect?The answers to the questions are different from one person to another. In most cases, a Zoom teeth whitening procedure is done twice a year. An average person who drinks coffee frequently and smokes daily will have improved tooth brightness - around 10 shades brighter. After the procedure is completed, the teeth will gradually start to regain their yellowish color over time, depending on how well you take care of them. On average, people who went through in office tooth whitening procedures noticed that their teeth stay white for months, although the initial brightness does not last more than a few weeks. The beauty of this system is that it is fast, efficient and has no side effects (although some patients did experience tooth sensitivity for one or two days after the procedure). Overall, Zoom teeth whitening is an excellent choice for anyone looking to get a bright and attractive smile.

Natural Tooth Whitening

Natural Tooth Whitening

No patience for bleaching? There may be another way to get white teeth, and it's as simple as munching on an apple.

To keep teeth bright and prevent yellowing, you need to remove the staining bacteria. This is exactly what happens when you chew certain foods that produce a high salivary flow. So, in addition to apples, take a bite out of guavas, pears, celery, carrots, sugar cane, cauliflower, and cucumbers. Another benefit: The fibre in some of these foods physically works to clean teeth and remove bacteria.

Two more tips to keep teeth bright:
1. Watch out for dark foods and beverages. Anything that can stain a white T-shirt can stain your teeth too. That means most varieties of berries, as well as soy sauce, red wine, many fruit juices, coffee, tea, and cola. You dont have to avoid them altogether, but immediately after indulging, rinse out your mouth with water, chew gum, or brush your teeth.

2. Keep in mind that citrus fruits contain acid that can cause enamel to deteriorate over time.

Teeth Whitening - Fluoride Therapy

Considering the vulnerability of enamel to demineralization and the daily menace of sugar ingestion, prevention of tooth decay is the best way to maintain the health of teeth. Most countries have wide use of toothbrushes, which can reduce the number of bacteria and food particles on enamel. Some isolated societies do not have access to toothbrushes, but it is common for those people to use other objects, such as sticks, to clean their teeth. In between two adjacent teeth, floss is used to wipe the enamel surfaces free of plaque and food particles to discourage bacterial growth. Although neither floss nor toothbrushes can penetrate the deep grooves and pits of enamel, good general oral health habits can usually prevent enough bacterial growth to keep tooth decay from starting.


These methods of oral hygiene have been helped greatly by the use of fluoride. Fluoride can be found in many locations naturally, such as the ocean and other water sources. Consequently, many seafood dishes contain fluoride. The recommended dosage of fluoride in drinking water is 1 part per million (ppm). Fluoride helps prevent dental decay by binding to the hydroxyapatite crystals in enamel. The incorporated fluoride makes enamel more resistant to demineralization and, thus, resistant to decay. Fluoride therapy is used to help teeth prevent dental decay.

Many groups of people have spoken out against fluoridated drinking water. One example used by these advocates is the damage fluoride can do as fluorosis. Fluorosis is a condition resulting from the overexposure to fluoride, especially between the ages of 6 months to 5 years, and appears as mottled enamel. Consequently, the teeth look unsightly and, indeed, the incidence of dental decay in those teeth is very small. However, it is important to note that most substances, even beneficial ones, are detrimental when taken in extreme doses. Where fluoride is found naturally in high concentrations, filters are often used to decrease the amount of fluoride in water. For this reason, codes have been developed by dental professionals to limit the amount of fluoride a person should take. These codes are supported by the American Dental Association and the American Academy of Pediatric Dentistry. The acute toxic dose of fluoride is ~5 mg/kg of body weight. Furthermore, whereas topical fluoride, found in toothpaste and mouthwashes, does not cause fluorosis, its effects are also less pervasive and not as long-lasting as those of systemic fluoride, such as when drinking fluorinated water. For instance, all of a tooth's enamel gains the benefits of fluoride when it is ingested systemically, through fluoridated water or salt fluoridation (a common alternative in Europe). Only some of the outer surfaces of enamel can be reached by topical fluoride. Thus, despite fluoridation's detractors, most dental health care professionals and organizations agree that the inclusion of fluoride in public water has been one of the most effective methods of decreasing the prevalence of tooth decay.

Teeth Whitening - Enamel

Tooth enamel is the hardest and most highly mineralized substance of the body, and with dentin, cementum, and dental pulp is one of the four major tissues which make up the tooth. It is the normally visible dental tissue of a tooth and must be supported by underlying dentin. Ninety-six percent of enamel consists of mineral, with water and organic material composing the rest. The normal color of enamel varies from light yellow to grayish white. At the edges of teeth where there is no dentin underlying the enamel, the color sometimes has a slightly blue tone. Since enamel is semitranslucent, the color of dentin and any restorative dental material underneath the enamel strongly affects the appearance of a tooth. Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5mm, and thinnest at its border, which is seen clinically as the cementoenamel junction (CEJ).
Enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate.The large amount of minerals in enamel accounts not only for its strength but also for its brittleness. Tooth enamel is the hardest substance in the human body, ranking a 5 on Mohs hardness scale. Dentin, less mineralized and less brittle, 3-4 in hardness, compensates for enamel and is necessary as a support.

Unlike dentin and bone, enamel does not contain collagen. Instead, it has two unique classes of proteins called amelogenins and enamelins. While the role of these proteins is not fully understood, it is believed that they aid in the development of enamel by serving as a framework support, among other functions.

Teeth Bleaching

Tooth bleaching, also known as tooth whitening, is a common procedure in general dentistry but most especially in the field of cosmetic dentistry. Many people consider white teeth to be an attractive feature of a smile. A child's deciduous teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker. This darkening is due to changes in the mineral structure of the tooth, as the enamel becomes less porous. Teeth can also become stained by bacterial pigments, foodstuffs and tobacco.

As white teeth are subconsciously associated with youth, they have become desirable. This has been made more apparent with the spread of American culture worldwide, where an especially white smile is coined a "Hollywood smile". The procedure to bleach teeth uses oxidising agents such as hydrogen peroxide or carbamide peroxide to lighten the shade of the tooth. The oxidising agent penetrates the porosities in the rod-like crystal structure of enamel and oxidises interprismatic stain deposits; over a period of time, the dentine layer, lying underneath the enamel, is also bleached. Tooth bleaching will generally last from 5 to 7 years but this is subjective depending on if you are a smoker and drink tea, coffee, etc.[1]

Teeth Whitening - Endodontic Therapy

Endodontic therapy is a sequence of treatment for the pulp of a tooth whose end result is the elimination of infection and protection of the decontaminated tooth from future microbial invasion. Although this set of procedures is commonly referred to as a root canal, this term is imprecise; root canals and their associated pulp chamber are the anatomical hollows within a tooth which are naturally inhabited by nerve tissue, blood vessels and a number of other cellular entities, whereas endodontic therapy includes the complete removal of these structures, the subsequent cleaning, shaping and decontamination of these hollows with the use of tiny files and irrigating solutions and the obturation, or filling, of the decontaminated root canals with an inert filling, such as gutta percha and a usually eugenol-based cement.

Methods of Teeth Whitening

There are two main methods of bleaching. The first involves applying a high concentration of oxidising agent for a short period of time, which is the so-called office bleach. This produces quick results but risks chemical burns to the soft tissues. Therefore, most in-office bleaching procedures use a light-cured protective layer that is carefully painted on the gums and papilla (the tips of the gums between the teeth). The bleaching agent is either carbamide peroxide, which breaks down in the mouth to form hydrogen peroxide, or hydrogen peroxide itself. The bleaching gel typically contains up to 35% hydrogen peroxide equivalent.

The alternative method involves using a thin mouthguard or strip to hold a low concentration of oxidising agent next to the teeth for as long as several hours a day for a period of 5 to 14 days. This is known as take-home or over-the-counter bleaching. This is a slower process but has fewer risks to the soft tissues. The bleaching agent is typically less than 10% hydrogen peroxide equivalent.

A typical course of bleaching can produce dramatic improvements in the cosmetic appearance of most stained teeth; however, some stains do not respond to bleaching. Tetracycline staining may require prolonged bleaching, as it takes longer for the bleach to reach the dentine layer. White-spot decalcifications may also be highlighted and become more noticeable. Bleaching is least effective if your teeth have white spots, decay or infected gums. It is also least effective when the original tooth color is grayish. Bleaching is most effective with yellow discolored teeth.

Recently, efforts have been made to accelerate the bleaching process by the use of light. Studies have shown varying results as to the efficacy of light-activated bleaching.

Side effects of tooth bleaching include: chemical burns (if a high-concentration oxidising agent contacts unprotected tissues, which may bleach or discolor mucous membranes), sensitive teeth, and overbleaching (known in the profession as "over white teeth"). Rebound, or teeth losing the bleached effect and darkening, is also an issue, with some studies showing the rebound effect over 30 days. A recent study by Kugel et al has shown that as much as 4 shades of lightness can be lost over 30 days with light-activated/office bleaching.

Risks of Teeth Whitening

The two side effects that occur most often are a temporary increase in tooth sensitivity and mild irritation of the soft tissues of the mouth, particularly the gums.[2] Tooth sensitivity often occurs during early stages of the bleaching treatment. Tissue irritation most commonly results from an ill-fitting mouthpiece tray rather than the tooth-bleaching agent. Both of these conditions usually are temporary and disappear within 1 to 3 days of stopping or completing treatment.

Individuals with sensitive teeth and gums, receding gums and/or defective restorations should consult with their dentist prior to using a tooth whitening system. Anyone allergic to peroxide (the whitening agent) should not use a bleaching product. Also, prolonged exposure to bleaching agents may damage tooth enamel. This is especially the case with home remedy whitening products that contain fruit acids

Bleaching is not recommended in children under the age of 16. This is because the pulp chamber, or nerve of the tooth, is enlarged until this age. Teeth whitening under this condition could irritate the pulp or cause it to become sensitive. Teeth whitening is also not recommended in pregnant or lactating women.

Today's common cosmetic dental treatment options

Today's common cosmetic dental treatment options include:

Whitening, or "tooth bleaching", is the most commonly prescribed cosmetic dental procedure. While many whitening options are now available, dentist-supervised treatments remain the recommended procedures for lightening discolored teeth.
Enamel shaping removes parts of the contouring enamel to improve the appearance of the tooth.[1] It may be used to correct a very small chip. The removed enamel is irreplaceable. It is also known as enameloplasty, odontoplasty, recontouring, reshaping, slenderizing, and stripping.
Bonding is an option for chipped or cracked teeth. It is a process in which an enamel-like dental composite material is applied to a tooth's surface, sculpted into shape, hardened, and then polished.
Veneers, ultra-thin, custom-made laminates that are bonded directly to the teeth, are an increasingly popular procedure. They are an option for closing gaps or disguising discolored teeth that did not respond well to whitening procedures.

Tooth whitener

Tooth whitener - whitening oral hygiene products. Product or system which is used for the tooth whitening.

A tooth whitener product can bleach the tooth, which means that it actually changes the natural tooth color. Bleaching products contain peroxide that help remove deep and surface stains. By contrast, non-bleaching whitening products contain agents that work by physical or chemical action to help remove surface stains only.

There can be two types of tooth whiteners:

Peroxide-containing whiteners or bleaching agents
Bleaching solutions contain peroxide, which actually bleaches the tooth enamel. These products typically rely on carbamide peroxide solutions as the bleaching agent. Carbamide peroxide comes in several different concentrations, ranging from 10% to 22%.
Peroxide-containing whiteners typically come in a gel and are placed in a mouthguard. Some products are used twice a day for two weeks, and others are intended for overnight use for one to two weeks. If there obtain the bleaching solution from dentist, he can make a custom-fitted mouthguard for patient that will fit his teeth precisely.
Whitening toothpastes (dentifrices)
Whitening toothpastes help remove surface stain through the action of mild abrasives, as do all other toothpastes. Unlike bleaches, whitening toothpaste does not alter the intrinsic color of teeth.

How white should I go when bleaching?

How white should I go when bleaching?
The answer to this question varies with person to person. The whitening that you want for your teeth should be according to your skin complexion. If you have a darker complexion, you should go for a shade that complements your skin. If you go for a very white shade, it would look unnatural. Another thing that you should keep in mind while selecting the whitening shade is the colour of your eyes. The whiteness of your eyes should match with that of your teeth colour. It is an excellent parameter for selecting the whiteness of your teeth. The choice of shade also depends on your sex. Generally, females are able to pull off a much whiter look compared to males. A very white shade might look weird on a guy while it would be perfect for a female.

Laser Teeth Whitening

What is laser teeth whitening all about ?
Laser teeth whitening is one the latest and the most effective methods of teeth whitening. Laser treatment involves using a beam of special laser light on the desired areas. Laser teeth whitening is popular beacause the procedure only takes an hour, and results can be seen instantly. It is costlier as compared to the other teeth whitening methods but gives good results instantaneously. The treatment begins by using the bleaching agents like hydrogen peroxide gel or carbamide peroxide gel on the teeth enamel. The gel is then activated using a controlled laser light. The result is that that the bleaching takes place more effectively and in a much lesser time. The teeth become whiter by up to 10 shades.

Below are the top 3 teeth whitening products available in the market:

Zoom – The Zoom Tooth whitening system by Discus Dental Inc is a very popular teeth whitening system available on the market. Part of its popularity is due to the product’s massive marketing exposure. The hydrogen peroxide based tooth whitener has a 32% hydrogen peroxide gel and an activator. The gel is then mixed with the activator to form a bleaching system of 25% hydrogen peroxide with a pH of 7.5 to 8.5. The system uses a mercury metal halide light within the range of 350-400nm.

BriteSmile - BriteSmile is another very popular teeth whitening system. The BriteSmile treatment consists of the BriteSmile Procedural Gel for whitening teeth. The pre packaged hydrogen peroxide compound with a 15% hydrogen peroxide concentration and a pH of 6.5 comes in a ready to use formula. An ‘accelerator’ is also used during the second and third procedure to increase the effectiveness of the whitener. The light used is either a gas plasma or LED (Light emitting diode) bleaching light having a wavelength between 400 and 500nm.

Ionic White - This is another widely used teeth whitening system that has gained popularity through TV exposure. The Ionic White tooth whitening system includes the Ionic White light, Whitening rinse, Whitening Rinse, Whitening Gel and the Whitening Gel Accelerator. The whitening gel contains silver ions that get activated when exposed to the blue LED light. It is also one of the cheapest tooth whitening treatments available in the market.

Are there any natural ways to whiten my teeth?

Are there any natural ways to whiten my teeth?
There are a few natural methods of teeth whitening, but they are very slow and relatively ineffective. The best way to have white teeth naturally is by avoiding foods and drinks that can cause tooth staining. This means one should keep away from smoking, drinking and consuming tea, coffee, etc… To whiten teeth naturally, you need to remove the bacteria that causes staining. This can be done by consuming food that produces a good flow of saliva like apples, guava, carrots, pears, sugar cane, celery, cucumbers and cauliflowers. The fibre content in these foods helps in removing the bacteria. One should also avoid consuming too many fruits that contain citrus as they can damage tooth enamel.

Are tooth whitening products safe?

Are tooth whitening products safe?
The answer is both yes and no. Yes if you use them the way they are supposed to be used, and no if you use them in excess or do not follow the instructions. The ingredients used in teeth whitening are known to be safe if used in proper quantities and in the right amount of time. Using such products without proper supervision from a professional dentist can cause you unnecessary harm. It is therefore advisable that teeth whitening products be used under proper supervision from expert professionals. If used without proper supervision and in excess, teeth whitening products do have some side effects as discussed above.

Why is teeth whitening so popular?

Why is teeth whitening so popular?
Teeth whitening is popular for various reasons. The most obvious reason why people choose teeth whitening is because it makes you feel great. It helps you improve your facial appearance and overall personality to a great extent. Good looking, white teeth give a very good impression about a person. People who have stained or discolored teeth find teeth bleaching very helpful. Shining white teeth give that added self confidence. Tooth whitening is also an easy and relatively cheaper procedure than many other forms of cosmetic surgeries. It takes just a few hours and a few visits to undergo teeth whitening. All these factors make tooth whitening a favorite with people.

A quick glimpse at history shows that white teeth have been around long before the arrival of seductive Hollywood smiles and billion-dollar bleaching campaigns. People have been doing this for thousands of years. Ancient Egyptians used a cream made from oxen hooves mixed with burned egg shells, pumice and water to whiten their teeth. Upper-class Romans added expensive imported urine to their teeth whitening mix (unaware that it was the ammonia molecules that were whitening their teeth). The Greeks had formulations and at the beginning of the Renaissance, Europeans were putting compounds on their teeth in a conscious effort to whiten them. Unfortunately, those compounds were essentially the equivalent of today’s Clorox. It ate the enamel away on the teeth. They had whiter teeth for a while, but then they started to see severe decay.

Today’s teeth whitening methods are safe and produce wonderful results.

How long does teeth whitening last?

How long does teeth whitening last?
This is a subjective question. First, it depends on the cause of your teeth becoming stained and discolored. If you are used to drinking tea, coffee, wine, etc, then it is likely that the whitening effect would not last long. The consumption of such liquids will cause your teeth to discolor again. Smoking can also contribute to this. In case your teeth are genetically stained, you might need a teeth whitening treatment again after a few years. Normally, teeth whitening done by professionals stays effective for 5 to 7 years. One thing that is good about teeth whitening treatments is that very rarely do people return to their original teeth condition before treatment.

Patients who smoke cigarettes or drink heavy quantities of dark, acidic liquids like: coffee, tea, red wine, colas, etc. will have to touch up their teeth more often than people who do not.

What method of teeth whitening is best for me?

What method of teeth whitening is best for me?
This depends entirely on your teeth condition, your budget, the results you want and the time you are willing to spend for teeth whitening. It also depends upon the purpose for which you want to whiten your teeth. If your main intention is to make your teeth stain free and shining white then you should go for the professional teeth whitening methods. Such methods might take more time and money, but they are more reliable and effective. If you are just generally worried about the color of your teeth then at-home whitening products are probably right for you. You can use them regularly without any worries of high costs and your teeth would look better over a period of time. If you want to have the best looking teeth for a special occasion like marriage or something, then you should go for faster methods like laser treatment. If you have the time and money, you should always go for a professional treatment after finding the right dentist.

Should I consult a dentist about teeth whitening?

Should I consult a dentist about teeth whitening?
Choosing a dentist for teeth whitening would be a wise decision. There are some risks involved and there are some possible complications. A dentist would be able to guide you on the best possible methods of treatment. An experienced dentist will not only guide you but also help in preventing the possible side effects of over-bleaching. In case you want to have custom kits that would fit your teeth properly for bleaching, a dentist would be able to create one for you. You can even consult a dentist about the possible side effects and risks involved. It is better to have experts guide you before you decide to opt for tooth bleaching.

Are there any side effects with teeth whitening?

Are there any side effects with teeth whitening?
While it is true that teeth whitening by bleaching does work, it does not come without side effects. There are many reported incidents of increased tooth sensitivity after bleaching. Prolonged exposure to bleaching agents can damage tooth enamel. If the treatment is not administered properly, there can be complications like gum irritation. The oxidizing agents are very strong and can damage the soft tissues of your mouth. The bleaching effect can cause some irritation and increased sensitivity to cold and hot fluids and sometimes even to air. In the case of home bleaching, there is a chance that some of the bleaching gel might be ingested by patients. In such a case, the person might experience burning or nausea.

According to a Brazilian study done in 2004, increased sensitivity is commonly an inherent characteristic of the bleaching process. During bleaching with carbamide peroxide, the bleaching agent actually causes a dissolution of isolated groups of enamel rod prisms. The dissolution of the individual enamel rod prisms is so thorough that the dentin actually becomes exposed microscopially. In turn, cold water that subsequently travels down the evacuated spaces causes a slight contraction of the now exposed odontoblastic process. This in turn causes sensitivity. It actually will continue until the temperature of the tooth warms back to body temperature.

When receiving professional teeth whitening, minimal sensitivity and good whitening results rely on factors such as pH, viscosity, stability and, most importantly, the rate at which the carbamide breaks down into hydrogen peroxide and then oxygen. Carbamide has been chosen by many manufacturers as it is more stable than hydrogen peroxide. However, this also causes a slower release of the oxidizing agent and necessitates longer procedures. Some manufacturers have tried to accelerate this by adding heat (in the form of light). This can have a minimal effect but it can also be a major cause of extreme sensitivity.

We have written an in-depth article on possible teeth whitening dangers located in the article section.

How does teeth whitening work?

How does teeth whitening work?
There are two types of tooth stains “extrinsic,” those stains that are on the surface of the tooth, and “intrinsic,” those stains that are on the inside of the tooth and show through the enamel as discoloration. While whitening toothpaste and chewing gums may be effective for removing extrinsic stains, they are not designed to work inside the tooth to remove the darker, more challenging instrinsic stains.

Some form of hydrogen peroxide gel, either hydrogen peroxide itself or a more stable version, carbamide peroxide, is the most effective material for removing the internal stains. When applied to the tooth, the hydrogen peroxide breaks down into water and radical hydroxyl ions. As these ions work their way through the dentinal tubules and into the tooth, they attach themselves to stain particles and effectively break the stains apart. With the stains removed the teeth appear whiter and brighter.

New Tooth Whitener Could Help Heal Teeth

New Tooth Whitener Could Help Heal Teeth

Tooth whiteners that could enhance teeth's natural healing ability may soon be available in over-the-counter gels and strips, according to a dental researcher who shared his team's latest findings today at the American Dental Association's national media conference.

According to Frederick Eichmiller, D.D.S., director of the American Dental Association's Paffenbarger Research Center (PRC) in Gaithersburg , MD , PRC scientists have created a "white with might" whitening formula that contains tooth remineralization agents.

Dr. Eichmiller explained that whitening can often open naturally occurring pores within teeth. These open tooth pores can cause temporary sensitivity to air as well as hot and cold food and drinks, a common side effect from tooth whitening.

Saliva contains minerals teeth need to heal themselves by closing these pores, but this process is slow. The "white with might" whitening formula replenishes essential minerals in teeth as it whitens, resulting in far fewer side effects for consumers.

"It's like having your cake and eating it, too, when it comes to tooth whitening,' Dr. Eichmiller stated, adding that laboratory and human clinical trials on this “white with might” technology substantiate the gel's effectiveness. Currently, the whitening gel and the remineralization ingredients are stored separately and combined just before applying to teeth. Dr. Eichmiller said PRC scientists are working on combining the two into a single product which could then be used in over the counter strips and paint on tooth whiteners.

Carbamide Peroxide vs Hydrogen Peroxide

Carbamide Peroxide vs Hydrogen Peroxide - What is the difference?
Carbamide peroxide breaks down into urea and hydrogen peroxide. Hydrogen peroxide is the active ingredient in both. Carbamide peroxide breaks down to about one third hydrogen peroxide, so an 18% carbamide peroxide solution has the same effect as a 6% hydrogen peroxide solution. The reason carbamide peroxide is more common is because it is much more stable than hydrogen peroxide, which deteriorates rapidly in the store/dentist shelves.

Carbamide Peroxide Therapy

Carbamide Peroxide Therapy
Carbamide peroxide (also known as urea peroxide) is the most popular bleaching agent used for teeth whitening. The main and active ingredient in carbamide peroxide is hydrogen peroxide. This ingredient has the effect of oxidizing stains, which leaves teeth looking whiter. There are many products and procedures which make use of carbamide peroxide. Dentists usually use a product with carbamide peroxide when undergoing in-office teeth whitening. It is also used in over-the-counter bleaching products, but in a much lower dosage.

Teeth Whitening products and procedures

You can select from a number of products and procedures available for teeth whitening.

Brush-on teeth whitening: It is the easiest and simplest form of teeth whitening. You just have to brush your teeth using brush-on teeth whitening products available in the market and leave them overnight.

Strips: There are various teeth whitening strips available in the market that you can use. These strips can be applied to your teeth and over a period of time the bleaching action will whiten them.

Teeth whitening toothpaste: A lot of teeth whitening products advertise "whitening." Whitening toothpaste can help a bit, but since it is only an abrasive, it can "whiten" the outerlayer only. True teeth whitening happens through the enamel and dentin. This requires hydrogen peroxide.

At-home kits: There are various at-home kits available for teeth whitening, such as trays, strips and gels. These products are effective and can be used by anyone at home. They are also cheaper than most other methods of teeth whitening.

Custom at-home kits: These kits are custom made for the shape of the teeth of the patient. The custom at-home kits are very effective as they fit the teeth properly and cover all areas.

Dental visits: This involves a visit to the dentist and determines the best method for teeth whitening. The dentist will either suggest an in-office treatment or laser-light assisted teeth whitening. Bleaching agents are applied to your teeth and treated with a special light to get the desired results. Lasers are used to increase the speed of bleaching. You can see the results in a single sitting.

What methods are available for teeth whitening?

What methods are available for teeth whitening?
There are various methods available for teeth whitening. Almost all of the methods require bleaching. Carbamide peroxide is one of the most commonly used bleaching agents. Bleaching can be done in various ways. You can either go for in-office bleaching or use over-the-counter products available on the market. You can even opt for tray-based tooth whitening systems that can be purchased at the counter or under the supervision of a dentist. Nowadays, you can go for laser-aided bleaching treatments that enhance and speed up the whitening process. Laser teeth whitening has become increasingly popular during the last few years. The treatments cost anywhere from $200 to $600.

It is also possible to whiten teeth using some sort of cosmetic restoration. Bonding, veneers, and crowns can be used to whiten teeth if the desired shade has not been reached from bleaching. Many hollywood celebrities who have gleaming white teeth have veneers. It is important to note that cosmetic restorations should be a last resort. People with tetracycline stained teeth often go with veneers as it is very difficult to get rid of the grey hue. However, a new bleaching method called Rod’s Deep Bleach has been showing promise for tetracycline stained teeth.

Why should I consider having a whiter smile?

Why should I consider having a whiter smile?
It’s quite simple. Your teeth need care and attention like any other part of your body. Over a period of time, teeth can become dull and yellow due to constant wear and staining. While brushing your teeth will keep them healthy and clean, it won’t necessarily keep them white and shiny. There are many reasons why your teeth lose their whiteness.

The most common reasons are:

Genetics: Your teeth may be shining white or have a shade of yellow. It all depends on your genes. If you are lucky enough, you might be be born with a nice set of white teeth. People with genetic problems have teeth that appear yellow or discolored. This is usually a result of the color in the dentin.

Physical causes: There can be various causes behind discoloration of your teeth. Teeth can become stained due to smoking, medications, tea, coffee, cigarettes and other tobacco products. Even soft drinks like cola can cause teeth to be stained.

Stained and discolored teeth look ugly and affect your appearance and personality. Teeth whitening can help you get back your naturally white teeth.

Studies have shown that not only do people who have whiter teeth look younger than people who don’t, but there is a correlation between high self-esteem and a white, confident smile. In addition to the aesthetic reasons, it is also true those people who have whitened their teeth:

- Develop a greater awareness of their teeth and become more compliant with their oral hygiene routine, including daily care and routine professional cleanings.

- Are more open to additional cosmetic dental procedures including replacing restorations and crowns and considering veneers.

- Typically have healthier gums and fresher breath.

Tooth Whitening - Tooth Bleaching

Tooth whitening or tooth bleaching are procedures that attempt to lighten a tooth's color in either of two ways: by chemical or mechanical action.

Working chemically, a bleaching agent is used to carry out an oxidation reaction in the enamel and dentin. The agents most commonly used to intrinsically change the color of teeth are hydrogen peroxide and carbamide peroxide. A tooth whitening product with an overall low pH can put enamel at risk for decay or destruction by demineralization. Consequently, care should be taken and risk evaluated when choosing a product which is very acidic.

Tooth whiteners in toothpastes work through a mechanical action. They have mild abrasives which aid in the removal of stains on enamel. Although this can be an effective method, it does not alter the intrinsic color of teeth.

Microabrasion techniques employ both methods. An acid is used first to weaken the outer 22–27 micrometers of enamel in order to weaken it enough for the subsequent abrasive force. This allows for removal of superficial stains in the enamel. If the discoloration is deeper or in the dentin, this method of tooth whitening will not be successful.

What are at-home procedures and products?

What are at-home procedures and products?

There are several types of products available for use at home, which can either be dispensed by your dentist or purchased over-the-counter.

Bleaching solutions. These products contain peroxide(s), which actually bleach the tooth enamel. These products typically rely on percent carbamide peroxide as the bleaching agent, carbamide peroxide comes in several different concentrations (10%, 16%, 22%).

Peroxide-containing whiteners typically come in a gel and are placed in a mouthguard. Usage regimens vary. Some products are used for about twice a day for 2 weeks, and others are intended for overnight use for 1-2 weeks. If you obtain the bleaching solution from your dentist, he or she can make a custom-fitted mouthguard for you that will fit your teeth precisely. Currently, only dentist-dispensed home-use 10% carbamide peroxide tray-applied gels carry the ADA Seal.

You also may want to speak with your dentist should any side effects become bothersome. For example, teeth can become sensitive during the period when you are using the bleaching solution. In many cases, this sensitivity is temporary and should lessen once the treatment is finished. Some people also experience soft tissue irritation—either from a tray that doesn’t fit properly or from solution that may come in contact with the tissues. If you have concerns about such side effects, you should discuss them with your dentist.

Toothpastes. All toothpastes help remove surface stain through the action of mild abrasives. "Whitening" toothpastes in the ADA Seal of Acceptance program have special chemical or polishing agents that provide additional stain removal effectiveness. Unlike bleaches, these ADA Accepted products do not alter the intrinsic color of teeth.

What is in-office bleaching?

What is in-office bleaching?

If you are a candidate for bleaching, your dentist may suggest a procedure that can be done in his or her office. This procedure is called chairside bleaching and may require more than one office visit. Each visit may take from 30 minutes to one hour.

During chairside bleaching, the dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues. A bleaching agent is then applied to the teeth, and a special light may be used to enhance the action of the agent.

A number of in-office bleaching agents have the ADA Seal of Acceptance, your assurance that they have met ADA standards of safety and effectiveness.

Lasers have been used during tooth whitening procedures to enhance the action of the whitening agent. No whitening products using lasers currently are on the ADA list of Accepted products.

Maintaining Your Whiter Smile

Maintaining Your Whiter Smile
In order to maximize the longevity of your whitening treatment, it is important to maintain excellent oral hygiene (brush and floss after every meal) and steer clear of some of the more common causes of discoloration (coffee, tea, red wine, etc.). To help avoid future staining, dentists often suggest using a straw, even with coffee and tea. Smokers wishing to undergo whitening treatment are advised to stop smoking in order to prevent the staining it causes. Discuss such considerations with your dentist during your initial whitening consultation.

The Teeth Whitening Procedure: In-Office vs. At-Home

The Teeth Whitening Procedure: In-Office vs. At-Home
Teeth whitening can be performed either in-office by your dentist or at home by you. While in-office whitening is considered to be much quicker and more effective, many appreciate at-home whitening for its ease of use and low cost. How exactly do the two options differ?

In-Office Whitening
The advantage of having your teeth whitened in the dental office is that this approach is safe, fast, and most effective. Typically, your teeth can be whitened 8 - 10 shades within 45 minutes, dramatically improving your appearance in the shortest possible time. Shade charts are used during the consultation stage of treatment to customize the perfect shade of white for your teeth. In-office whitening is unique in this respect, as your dentist has more control over achieving your specific teeth whitening goals.

During your teeth whitening procedure, you are made comfortable while your teeth are prepared. Your dentist uses a tissue barrier (gel or rubber guard) to protect the lips and gums from a whitening gel that is applied to the teeth.

The application of the whitening gel occurs in three sessions over the course of the visit. A special lamp is used to activate the whitening gel and speed up the whitening process. Once the gel is activated, it remains on the teeth for 15 minutes until the next application.

Learn more about commonly used in-office whitening agents.

At-Home Teeth Whitening
Although many people opt for the "once-and-done" approach to teeth whitening associated with in-office treatment, some people prefer the at-home method. The most effective at-home whitening system is a prescription-strength gel kit your dentist provides. Most kits contain mouth trays that you fill with the whitening gel and place over your teeth for up to four hours.

While the dentist-prescribed at-home whitening system is more effective than other at-home options, you may opt for a less expensive over-the-counter teeth whitening kit. These kits may contain whitening gel and application trays, or whitening strips that you place on the surface of your teeth.

At-home teeth whitening requires several hours of application over a 5 - 14 day period, and the results are typically not as satisfactory as those achieved with an in-office approach.

Whitening has become popular to the point that many toothpastes and mouthwashes are now infused with whitening agents. Toothpaste whitening is an inexpensive and relatively ineffective whitening option.

Your dentist can help you determine which brand of whitening may best serve your esthetic goals.

Teeth Whitening Considerations

Teeth Whitening Considerations
More often than not, teeth whitening works adequately. Teeth whitening procedures performed by your dentist may potentially whiten your teeth up to 14 shades, correcting serious discoloration issues.

Occasionally tooth discoloration is so severe that whitening alone cannot fully treat the problem. Such situations may require a combination of whitening and the placement of custom porcelain veneers on specific discolored teeth. You may opt for veneer treatment alone rather than a teeth whitening regimen. Consult your dentist to determine the best course of action for your unique oral concerns.

Your dentist will also advise you to avoid food and drink that could stain your teeth for about a week, as well as to refrain from smoking.

Teeth Whitening: Customize Your Bright, White Smile

Teeth whitening is the most commonly requested cosmetic dentistry procedure. Teeth whitening falls into the cosmetic dentistry category because it is designed to enhance your appearance by reducing tooth discoloration and staining to elicit a brighter, whiter smile.

The Prevalence of Tooth Discoloration
Tooth discoloration and staining is a relatively common problem. Teeth are porous and are therefore not stain resistant. Red wine, soda, coffee, and tea, among other food and drink, contribute to the discoloration of teeth over time. Medications such as the antibiotic tetracycline may cause significant staining, resulting in yellow, grayish teeth. Smokers’ teeth can become permanently stained if the discoloration is not treated in a timely manner.

Tooth brushing alone can’t brighten teeth dulled by years of exposure to such discoloring agents. In fact, people with dull teeth sometimes over-brush in an attempt to eliminate stains, and this can harm the enamel.
