A veneer is a thin layer of
material placed over a tooth, either to improve the
aesthetics by correcting stained, chipped, decayed or
crooked teeth or to protect damage to a tooth's surface.
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.
