Teeth whitening or bleaching is typically a procedure that people at large undergo to change the color of their teeth, which leads to a improved smile. Teeth tend to darken with age. Also, their appearance can be affected by the accumulation of surface stains acquired from the consumption of certain foods or drinks or the use of tobacco products.
In addition, the perception of color of teeth is affected by individual skin tone and make-up. Irrespective of the real color of their teeth, people with darker skin tone or who use dark makeup will appear to have brighter teeth.
Although teeth are not naturally meant to be completely white, many of us wish to have a brighter/whiter smile. Responding to this desire, a wide range of "whitening" options have become available to the patients.
Most bleaching products are peroxide-based and are actually capable of altering the tooth color. However, not all tooth discolorations respond to bleaching treatment. Individuals contemplating bleaching should consult a dentist to determine the cause of the tooth discoloration and to determine whether the bleaching treatment will have the desired result. This step is especially important for patients with fillings, root canal treatments, crowns and/or with extremely dark stains on the front teeth.
There are two ways teeth bleaching can be done. Office bleach or home bleach. Bleaching done in the dental clinic by a professional is called as office bleach. While home bleaching is done by the patient using customized trays under the professional guidance.

Do toothpaste whiteners work?
Whitening toothpastes typically only clean surface stains and don’t actually change the color of the teeth. There may be some visible results but the teeth aren’t actually being whitened.
