to remove stains and discoloration. Whitening is among the
most popular cosmetic dental procedures because it can significantly
improve the appearance of your teeth at much less cost and
inconvenience than other techniques.
There are two types of tooth whitening Non-Vital
Whitening and vital whitening. non-vital whitening is done
on a tooth which no longer has a live nerve due to a root-canal
treatment done earlier .Vital whitening means that the procedure
is being done on teeth that have live nerves.

In case of non-vital whitening, a whitening agent is placed
inside the tooth and a temporary filling is done. In case
of vital whitening a gel like whitening solution, is put in
a tray that resembles a night guard or mouth guard. It is
then placed over the teeth for a certain period of time .
Most common whitening agent is hydrogen peroxide. The duration
of treatment depends on the extent of discoloration.

- There may be mild gum irritation
- This procedure should not be considered for a pregnant
woman as the effect of the whitening materials on the development
of the fetus is unknown.
