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.
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.
It is best to have an exam by a dentist and hygienist to determine if your teeth and gums are healthy enough for whitening.
