As we get older our teeth become discoloured through smoking, coffee, red wine and many other foods and drinks. Regardless, of how well we brush our teeth loose their whiteness.
Teeth whitening, also called Dental bleaching is a common procedure in general dentistry but most especially in the field of cosmetic dentistry. A child’s baby teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth, as the enamel becomes less porous.
Teeth can become stained by bacterial pigments, foodstuffs and tobacco. There are many methods to whiten teeth: bleaching strips, bleaching pen, bleaching gel, laser bleaching, and natural bleaching. Laser bleaching uses light energy to accelerate the process of bleaching in a dental clinic.
The effects of bleaching can last for several months, but may vary depending on the lifestyle of the patient.
