Cosmetic Dentistry
Tooth discoloration may be caused by staining, as with the administration of antibiotics, aging, or chemical damage to the teeth. Dental bleaching may be 80% to 100% effective and may be instituted before the use of crowns or veneers. Bleaching treatment is a low-cost treatment for tooth discoloration. The disadvantage in using the bleaching process is the sore gums or teeth from the bleach.
