Dental veneers are thin, tooth-colored shells made of porcelain or resin composite materials that are used in cosmetic dentistry to correct the appearance of teeth. Veneers are attached to the front surface of the teeth in order to improve their color, size and shape. Veneers also strengthen and replace damaged enamel, as enamel does not grow back. People who have chipped, stained, broken, or small teeth find that veneers effectively transform the look of their teeth giving them a pleasing smile.
