In dentistry Veneer is a thin layer of tooth like material, which is placed over the existing tooth surface with minimal preparation, to improve the esthetics of a tooth with regards to color or position. Multiple veneers can close spaces between teeth, lengthen teeth, provide uniform color, shape and symmetry and make the teeth appear straight.
There are two types of materials used to fabricate a veneer; composite resin and dental porcelain. A composite resin veneer is directly placed (built-up in the mouth) by the Dentist. In contrast, a porcelain veneer is indirectly fabricated by a dental technician in a dental laboratory and later bonded to the tooth by the Dentist.
