During the final “bonding” visit, also about one or two hours, the veneers are placed on the tooth surface with water or glycerin on the teeth to check their fit and 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 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.
Teeth that are badly stained, shaped or crooked may be improved by a veneer placed on the surface of the affected teeth.
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 with 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 it`s necessary to remove a small amount of enamel from your teeth to accommodate the shell.
