Tooth whitening is the process by which the color of natural teeth is made whiter by the use of whitening products. Tooth lightening by gels is done by applying a carbamide peroxide gel or paste to the teeth; this gel is known as tooth-whitening gel.

The use of tooth-whitening gels is a very popular cosmetic dental procedure, which is available as a home product, too. The whitening gel is a special dental product that can be applied to the teeth on a frequent basis and is considered to be one of the safest products used in dentistry. Its results in effecting a whiter tooth are immediate. This gel is made up of powerful bleaching ingredients, such as hydrogen peroxide and carbamide peroxide, which bleach the stains within the teeth. Many types of tooth-whitening gels are available now.

Tooth whitening by the use of gels is very effective because the gel works deep into the tooth to bring about the whiteness in considerably less time than other products. Other products whiten teeth on the outer layer in a short time, but the result may be temporary.

Children who are above two years of age can also use tooth-whitening gels. Since these gels contain no fluoride, the possibility of toxicity due to the swallowing of the gel is ruled out. Tooth-whitening gels function on the whitening effects of carbamide peroxide. This provides the vitamins C and E, and these ingredients stimulate the production of healthy mouth tissues and fight the germs that cause bad breath, without the aid of alcohol or other harmful ingredients.

Whitening teeth with the use of gels is the most popular cosmetic dental procedure because it can significantly improve the appearance of the teeth at much less cost and without the inconvenience of other techniques. This is also the reason why a good majority of dentists use tooth-whitening gels.
