Veneers are thin, custom-made shells designed to cover the front surface of teeth to improve your tooth’s appearance. These shells can be made of porcelain or composite resin, and they are permanently bonded to the front of your teeth changing their color, shape, size, or length. Veneers are similar to crowns, but they don’t require as much tooth structure to be removed. This makes veneers ideal for teeth without cavities or existing fillings
