The outer layer of our teeth is referred to as the enamel. As we age, the enamel wears down, and the layer below (called dentin) begins to show. The dentin is a yellow-colored substance, and once the enamel has worn away, the dentin can cause our teeth to have a yellow appearance. Teeth whitening procedures help to restore teeth to a bright white color.
Teeth Whitening Procedures
There are two popular teeth whitening procedures offered by your dentist. The first consists of an in-office teeth whitening procedure. This option 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.
The second method involves the use of take-home whitening kits. These at-home whitening kits are available for purchase from your San Ramon, CA dentist. The strength of the gel used 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 or overnight for a few days or weeks depending on the product.
It's best to consult your dentist to understand which whitening option is best for you.
