Though teeth whitening used to be restricted to dental offices, consumers now have more choices, including dentist-prescribed/dispensed whitener for at-home use, spa/mall whitening treatments and over-the-counter whiteners for at-home use, according to Teeth Whitening Reviews. The two main types of whitening are bleaching and non-bleaching whitening.
Bleaching products
Over-the-counter and dentist dispensed bleaching products with a neutral pH and 10 percent carbamide peroxide, notes the American Dental Association (ADA), are typically considered both safe and effective whiteners. Many will carry the ADA Seal and are designed to remove surface and absorbed stains.
Non-bleaching Products
The ADA categories any non-bleaching whitening product as a whitening toothpaste. They do not contain peroxide and utilize abrasives, polishes and other chemicals to remove stains from the surface of the teeth only. Whitening toothpastes will not change the natural color of the tooth like bleaching will.
Considerations
Tooth whitening products, indicates the ADA, aren't regulated by the FDA so consulting your dentist is advised. Since some products can cause tooth or gum sensitivity, and some products work better on different kinds of staining, a proper diagnosis and recommendation is a crucial element in whitening success.
