Some people have worn away the edges of their teeth resulting in a prematurely aged appearance, while others may have malpositioned teeth that appear crooked. Multiple veneers can close these spaces, lengthen teeth that have been shortened by wear, fill the triangles between teeth caused by gum recession, provide a uniform color, shape, and symmetry, and visually make the teeth appear straight.
A veneer is a thin layer of restorative material placed over a tooth surface, either to improve the aesthetics of a tooth, or to protect a damaged surface.

In the past, the only way to correct dental imperfections was to cover the tooth with a crown.
Today, in most cases there are several alternatives: crown, composite resin bonding, cosmetic contouring or orthodontics. Non-permanent dental veneers are also available. These dental veneers, made from a flexible resin material, are molded to existing teeth and are removable.
