Over the years, a normal condition for teeth is to lose their bright color. Nutrition and age play an important role for a normal denture. Tooth whitening is a painless dental procedure that removes dye pigments and dyschromias.

Tooth whitening can be done either in the dental clinic or at home. Tooth whitening in the dental clinic is conducted with especially approved by the EOF materials and the contribution of special lighting devices. Tooth whitening at home is done using tooth whitening guards, which they are especially custom made for you. You simply place the bleaching gel under the advice of your treating dentist.
The treatment varies depending on the primary color of your teeth and how the bleaching will be done, at home or at the dental clinic.
Tooth whitening is generally a safe procedure as long as your dentist does it in the proper way and uses approved materials by the EOF.
Therefore, before performing tooth whitening visit your dentist and get proper information about the whole procedure.
