This process, which uses carbamide peroxide, allows lightening enamel and dentine colouration. Teeth whitening is a procedure which has been used for some time in cosmetic dentistry.
Prior to whitening, the dentist performs a full exam and cleaning to ensure that the gums and teeth are healthy. That being said, whitening may be inadvisable for some people. The dentist can detect these contraindications and inform patients.
Tobacco and certain foods and beverages like red wine and coffee affect teeth colour and make them lose their lustre. Also, with age, teeth get darker.
Whitening can be done on the enamel of natural and healthy teeth; It is inappropriate and has no effect on veneers, composite fillings, crowns and bridges. After whitening, some patients experience temporary tooth sensitivity that fades in just a few days. This treatment is not recommended for women who are nursing or pregnant.
