Our teeth can discolor throughout the years as our enamel wears down. The wearing down of enamel allows dentin, a yellow colored 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 a professional whitening gel product.
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 and the use of a curing light on the teeth after the gums have been protected with a special shield.
The second method, involves the use of take home professional whitening kits. These whitening kits are purchased from your doctor for use at home. A custom tray is fabricated for your teeth and whitening gel is dispensed for your use. The strength of the gel used in these kits is lower than that used for in-office bleaching, and thus the gel can be applied for longer periods of time. Usually the trays are worn a couple hours a day for a few days or weeks depending on the product.
Its best to consult your dentist to understand which whitening option is best for you.
