In dentistry, a veneer is a thin layer of material placed over a tooth, either to improve the aesthetics of a tooth or to protect the tooth's surface from damage. There are two main types of material used to fabricate a veneer: composite and dental porcelain. A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental laboratory, and later bonded to the tooth, typically using a resin cement such as Panavia. In contrast, a porcelain veneer may only be indirectly fabricated.
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.
Non-permanent dental veneers, which are molded to existing teeth, are a feasible option as well. These dental veneers are removable and reusable, and are made from a flexible resin material
It is also applied to yellow teeth that won't whiten. Thin veneers is an effective option for aging patients with worn dentition. In many cases, minimal to no tooth preparation is needed when using porcelain veneers.
