Having whiter teeth has become the number one aesthetic concern of many people and there are numerous ways to approach this. The most popular way is to use a home teeth-whitening system that will whiten teeth dramatically for most people. Since teeth whitening only works on natural tooth enamel, it is important to evaluate replacement of any old white fillings, crowns, etc. to match the newly bleached teeth.
Teeth whitening is not permanent. A touch-up maybe needed every several years, and more often if you drink coffee, tea, or wine or if you smoke.
