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.
