Tooth whitening lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look. Most dentists perform tooth whitening.

There are two main types of whitening procedures. Vital whitening is performed on teeth that have live nerves. Non-vital whitening is done on a tooth that has had root-canal treatment and no longer has a live nerve

Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain the brighter color.
