Home Teeth Whitening Trays To Whiten Teeth

Since 1990, dentists have used tray-based methods of whitening teeth more than any other teeth whitening system. Nowadays, the same treatments are available at home, either dispensed by your dentist or bought over the counter. In this article, we will look at each method in turn.

Dentist Dispensed Home Teeth Whitening Trays
These are the only type of home teeth whitening trays approved by the American Dental Association. No over the counter products are approved for home use. The great advantage of this method is that it is carried out under the supervision of a dentist, so there are no worries about safety.

All ADA approved home teeth whitening trays contain the same active ingredient, a 10% solution of carbamide peroxide, though dentists will sometimes use a stronger solution if they feel that your teeth warrant it. Your dentist will custom fit the tray to your mouth, so there is no danger of tooth damage caused by an ill fitting tray.

Dentist dispensed home teeth whitening trays generally use a slightly stronger concentration of bleaching agents than over the counter products, which means that the treatment doesn't take as long. A home teeth whitening tray from your dentist will generally work in just a few hours, as opposed to weeks or even months for an over the counter home teeth whitening tray.
