Teeth Whitening
Our teeth can discolor through the years as our enamel wears down. The wearing down of enamel allows dentin, a yellow color substance that makes the core of our teeth, to show through. This is what gives our teeth a yellowish tint. Teeth whitening helps restore teeth to a shiny white color through the use of bleach.
Teeth whitening methods
There are two popular teeth whitening options available through your dentist. The first, in-office teeth whitening, produces a significant color change in your teeth in a short amount of time, usually within an hour. The procedure is done at the dentist's office by applying a high-concentration peroxide gel on the teeth after they have been protected with a special shield.

Its best to consult your dentist to understand which whitening option is best for you.
