Veneers are an important tool for the cosmetic dentist. A dentist may use one veneer to restore a single tooth that may have been fractured or discolored, or multiple teeth to create a "Hollywood" type of makeover. Many people have small teeth resulting in spaces that may not be easily closed by orthodontics. 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, provide a uniform color, shape, and symmetry, and make the teeth appear straight

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 or porcelain veneer or even cosmetic contouring or orthodontics

Non-permanent dental veneers are available in some places. These dental veneers are molded to existing teeth and are removable and reusable and are made from a flexible resin material. Do it yourself at home kits are also available for the impression-taking process. Actual veneers are made in the lab and sent to the wearer through the mail.
