Veneers are thin pieces of porcelain cemented over the front of your teeth to change their colour or shape. Veneers are used on teeth with uneven surfaces or are chipped, discoloured, unevenly spaced or crooked. They have a longer life expectancy and colour stability than bonding, and highly resistant to permanent staining from coffee, tea, or even cigarette smoking. They are almost always used in “Smile Makeover” cases.
Porcelain veneers can mask undesirable defects, such as teeth stained by tetracycline, by an injury, or as a result of a root-canal procedure. They are ideal for masking discoloured fillings on front teeth. Patients with gaps between their front teeth or have teeth that are chipped or worn may consider porcelain veneers.
At least three appointments are needed: diagnosis and treatment planning, preparation, and cementation.
During the tooth preparation visit, a local anaesthetic may be given to ensure the treatment is painless. The shape of the teeth is modified and a mould is taken and sent to the laboratory for fabrication of the veneers. At the final "bonding" visit, the veneers are checked for fit and colour before being permanently bonded to the teeth using special light activated adhesives.
