What is teeth whitening ?

Teeth whitening involves bleaching your teeth to make them lighter. It can’t make your teeth brilliant white, but it can lighten the existing colour by several shades.

Tooth whitening has become one of the most frequently requested dental procedures by the public. The public has come to demand whiter, more perfect smiles and in response many choices for tooth whitening have been made available. These include home-based products such as toothpastes, gels, and films, as well as in-office based systems where products containing highly concentrated bleaching agents are applied under professional supervision. The profession and public have been aware of certain risks related to tooth whitening such as increased tooth sensitivity and gingival irritation. New research has shown that there are other risks such as tooth surface roughening and softening, increased potential for demineralization, degradation of dental restorations, and unacceptable color change of dental restorations. The new research is also focused on optimizing whitening procedures to reduce tooth sensitivity and to increase the persistence of the whitening.

What are the teeth whitening methods?

Teeth whitening can be done at home or at a certified dentist’s clinic.

At home you can use two types of products:

1) Home type products. These are shipped mostly with low density gels to protect the customers. You can buy them at the stores or online easily.

2) Professional type of products. These type can be obtained only from a dentist. As the product is high density you need to use it very carefully. Your dentist will explain you all the procedures and details.

At a dentist version is applied only at the clinic by a dentist. The gel has a very high concentration and can harm your gum if not applied by a professional. The procedure is rather short thanks to the acceleration by a special light.
