Veneers can help improve your smile. A Veneer is a thin shell of porcelain or plastic that is bonded to a tooth to improve its color and shape. A Veneer generally covers only the front and top of the tooth. Veneers can be used to close spaces between teeth, lengthen smaller or misshapen teeth, or whiten stained or dark teeth. When teeth are chipped or beginning to wear, Veneers can protect them from damage and restore their original looks.
