A porcelain veneer is a very thin shell of durable porcelain which is bonded to the front surface of a patient's front teeth. Veneers are a beautiful and conservative way to change the shape, shade or size of the front teeth to improve their appearance. Veneers require less shaping of the tooth and removal of tooth structure when compared to crowns.
For best esthetic results, it is usually better to bond porcelain veneers to several teeth in a row as opposed to only 1 or 2. The dentist will work together with you to decide whether veneers would be beneficial for your smile and the optimal health of your mouth.
