Tooth whitening (or bleaching) is a simple, non-invasive dental treatment used to remove stain from natural tooth enamel and is an ideal way to lighten the shade of most teeth. Since whitening only works on natural tooth enamel, any existing fillings or crowns may not match after the tooth color has changed. If you have existing dental work on or in your front teeth it is important to have the dentist evaluate your teeth prior to starting any bleaching system.
There are several ways to whiten teeth. All the methods are based on a bleaching gel that is peroxide based. The difference between the methods is the strength and mode of applying this bleaching gel to the teeth. The most popular method is using a home tooth whitening system. The dentist can recommend which system would be best for you.
Tooth whitening is not permanent and can be repeated. Over time the teeth can accumulate new stains, this will occur faster if you smoke, drink coffee, tea, or wine.
