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.
Veneers have a longer life expectancy and color stability than bonding, and highly resist permanent staining from coffee, tea, or even cigarette smoking.
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 bonding.
During the tooth preparation visit, usually lasting one to two hours, the teeth are lightly buffed to allow for the small added thickness of the veneer. Usually, about a half a millimeter of the tooth is removed. During the same visit, a mold is taken of the teeth, and sent to the laboratory for the fabrication of the veneers.
For the permanent porcelain veneers, dentists will create them by using all data thet have collected from first visit such as your gum level, your smile line which measure from the lower border of upper lip when you perform the broad smile, the natural tooth color compare with your desired tooth color. All to ensure the best result to improve your smile as you wish.
