Teeth whitening occurs in two ways: First, stains on the outer layer of the tooth and under the surface of the enamel are removed. Second, the appearance of new spots is prevented. This is achieved by removing and rinsing the spots, and protecting the teeth against stains. How does stain removal work? The elimination of stains on the outer layer of the tooth requires chemical and physical actions, such as the removal and chemical alteration of the spots.

These actions destroy or alter the stains of the outer layer of the enamel, and, as a result, whiter and brighter teeth are obtained. To remove the stains that accumulate under the enamel, you need to bleach the surface, which is a chemical process that involves removing the color by oxidizing the molecules of the stain. Whitening methods vary depending on the concentration of peroxide, which is the whitening agent used, and allows to control the degree of whiteness that is desired in the teeth.

The methods of tooth whitening include professional treatments performed by dentists, whitening toothpaste, whitening strips and home whitening systems.  (Know everything you need to know about teeth whitening.)
