In dental terms, what is the difference between a veneer and a crown?

You can think of a veneer as a partial crown. Ofcourse that is not the exact definition. A crown is when the whole tooth surface is replaced or covered by a restorative material. A veneer is when part of the surface only is covered usualyy the labial surface though on a certain cases the palatal surfaces might be covered e.g acid reflux and the subsequent loss of palatal enamel layer(erosion).

In dental terms, what is the difference between a veneer and a crown?
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 tooth surface. There are two types of material used in a veneer, composite and 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.








Crown refers to the restoration of teeth using materials that are fabricated by indirect methods which are cemented into place. A crown is used to cap or completely cover a tooth.
Reply:veneer means coverage, so u can say a full veneer ( crown) or partial veneer (laminates or other type)...
