Porcelain veneers can mask undesirable defects, such as teeth stained by tetracycline, by an injury, or as a result of a root-canal procedure, and are ideal for masking discolored fillings in front teeth. Patients with gaps between their front teeth or teeth that are chipped or worn may consider porcelain veneers.
Typically, veneers entail at least three appointments: diagnosis and treatment planning, preparation, and cementation.
During the tooth preparation visit , local anesthetic is given to ensure the treatment is painless. The teeth shape is modified and a mold is taken of the teeth, and sent to the laboratory for the fabrication of the veneers. At the final "bonding" visit, also about one or two hours, the veneers are checked for fit and color before being permanently bonded to the teeth using special light activated adhesives.
