Teeth that are badly stained, oddly shaped or crooked may be improved by a placing a veneer placed on their surface.
Veneers are thin pieces of porcelain or plastic cemented over the front of your teeth to change their color or shape. Veneers are used on teeth that have uneven surfaces or are chipped, discolored, oddly shaped, unevenly spaced or crooked. Little or no anesthesia is needed. Veneers have a longer life expectancy and color stability than bonding and highly resist permanent staining from coffee, tea, or even cigarette smoking.
Veneers are usually made by a dental lab technician working from a model provided by your dentist. Veneers are usually irreversible, because the procedure requires removing a small amount of enamel from your teeth to accommodate the shell.
Porcelain veneers can mask undesirable defects, such as teeth stained by tetracycline, an injury, or as a result of a root-canal procedure. They are ideal for masking discolored fillings in front teeth. Patients with gaps between their front teeth or chipped and worn teeth may consider porcelain veneers.
Typically, veneers entail at least three appointments: diagnosis and treatment planning, preparation, and bonding.
The tooth preparation visit usually lasts one to two hours. The teeth are lightly buffed to allow for the slight added thickness of the veneer. Usually, about a half a millimeter of the tooth is removed, which may require a local anesthetic. During the same visit, a mold is taken of the teeth and sent to the laboratory for the fabrication of the veneers.
During the final bonding visit, which also takes about one or two hours, the veneers are placed on the tooth surface with water or glycerine to check their fit and to get a sense of the shade or color. While the veneers are resting on your teeth, they can be adjusted with various shades of cement to match the color of your teeth. To apply the veneer, the tooth is cleansed with specific chemicals to achieve a good, strong, lasting bond. Once a special cement is sandwiched between the veneer and tooth, a visible light beam, or laser, causes a catalyst to be released, hardening the cement.
During the two-week adjustment period that follows, you may notice a change in the size and shape of your teeth. It is important to brush and floss daily. After one or two weeks, you'll return for a follow-up appointment. Porcelain veneers are reasonable facsimiles of natural teeth, not perfect replacements. It's not uncommon to see slight variations in the color of porcelain veneers upon close inspection, as these variations can occur even in natural teeth.
For certain patients, no preparation of the teeth may be necessary. Please see our specialties page for more information.
