Crowns are a type of dental restoration that utilize a variety of materials including porcelain, gold, ceramic, etc. The restoration encircles the entirety of the tooth and is placed over a broken tooth that is damaged by rampant decay or when there is weakening of a tooth that has been treated with a conventional filling. A crown allows for protection of the tooth by covering it both on the biting surface as well as the sides of the tooth.
For a crown preparation, we first begin with reducing a millimeter or two of the tooth. This reduction makes room for the future crown which will protect the remaining tooth structure. After the reduction, a temporary crown will be placed on your tooth while the dental laboratory constructs a permanent crown that contours to the shape of the adjacent teeth. In two weeks’ time, the temporary crown is replaced and the permanent crown is cemented on.
