The other technique is to coat bleaching teeth veneers.
The Direct bleach teeth: what are the different techniques?
In smokers or heavy drinkers of tea or coffee, the dentist performs a scaling and polishing. Smoking cessation is strongly advised.
When teeth are naturally darker, one uses techniques of enlightenment that is to apply a lightening product specific (carbamide peroxide, hydrogen peroxide or sodium perborate for vital teeth).
Application of the product is lightening using a gutter individual conducted by a test of hearing. It occurs once in the dentist’s office or in several sessions at home. Note that the time needed for teeth whitening can sometimes be shortened by activation using a laser or a specific lamp.
The principle of this method is essentially identical to that proposed by the home whitening kits over the counter. Some propose to apply the product using a brush strip or gutter as a dentist, except that it is not custom but standard.

Facets: an alternative technique for white teeth
One way to make teeth white is to stick veneers, thin strips of composite material on the teeth, whose surface was prepared.
Veneers are affixed directly to the dentin, and not on the enamel.
This process yields a very successful cosmetic result, but instead, it requires more cutting teeth. This problem is less with porcelain veneers. The other disadvantage is the potential for delamination.
