Cosmetic veneers (sometimes called porcelain veneers or laminates) are wafer thin custom made shells of tooth colored material, designed to cover the front surface of the tooth to improve your appearance. Veneers are bonded to the front of the tooth changing their color, shape, size or length.
Dental veneers can be made from porcelain or resin composite material. Porcelain veneers resist stains better than resin and mimic the light reflecting properties of natural teeth. Resin veneers can be placed in one visit, while porcelain veneers require multiple visits (usually two). You will need to discuss the best choice of veneer material with your dentist.
The advantage of veneers versus crowns is the amount of tooth preparation is more conservative to achieve the desired esthetic result.
