Whitening of the teeth is performed for patients who desire a brighter smile. Tooth whitening can be performed to reduce discoloration and staining, or simply to provide the patient with whiter, brighter teeth.
The teeth of humans display a wide range of shades of white. There is no one specific color that a person’s teeth are supposed to be.

Teeth enamel discoloration can be caused by staining, aging, or chemical damage or naturally discolored, such as teeth with tetracycline or fluorosis staining. Common causes of teeth discoloration are medications, coffee, tea or cigarettes. Genetics play an important role, some people have naturally whiter enamel than others.
