What is a crown?

If a tooth is grossly broken down either because of decay or because a large piece has fractured off, the dentist may decide to crown it. A crown (often referred to as a cap) is an artificial tooth made from porcelain and/or metal alloy (in days of old, gold!) and which fits over the top of the original tooth. Obviously, before a crown can be fitted, it is necessary to prepare the tooth by trimming a little off from each surface to make room for the crown. The dentist will then take an impression of your mouth (and tooth) and this is then sent to a laboratory where the crown is made. The finished crown is cemented onto your tooth at a second visit.

If the tooth to be crowned has already been root-filled, the dentist may affix a post into the roots of the tooth to act as a foundation on which to build the crown.
