Porcelain veneers have a natural appearance because they are custom-sculpted to fit each individual tooth, according to the American Academy of Cosmetic Dentistry. Compared to crowns, veneers requires less alteration, so the original tooth remains more intact. Veneers are bright white and stain-resistant against common substances, such as tea, coffee and cigarette smoke, making them cosmetically attractive.
Porcelain veneers are useful for repairing cosmetic dental issues, such as discolored or worn teeth, WebMD explains. Since they allow dentists to alter the size and shape of teeth, veneers fill gaps and repair chips, irregular shapes and misaligned teeth. Porcelain veneers are permanently bonded, and their thin construction, enamel-like strength and light-reflecting surfaces mirror the properties of natural teeth.
Porcelain veneers are made up of thin layers of ceramic and a coating of light-sensitive resin, the American Academy of Cosmetic Dentistry states. The procedure typically requires the dentist to remove less than 1 millimeter of the original tooth and enamel. Some patients may be candidates for minimal- or no-prep veneers, created more quickly because the dentist performs less alteration on the natural tooth. Veneers require the same maintenance as normal teeth, but patients should visit a dentist annually for a professional polish. They should also avoid destructive habits, such as grinding teeth.
