Crowns are used to cover a tooth that is likely to break, or is too broken down to be restored with a large filling.Crowns are used to cover a tooth that is likely to break, or is too broken down to be restored with a large filling. Crowns provide strength and protection against fracturing of the tooth. It takes two appointments to restore a tooth with a crown.  The first appointment consists of preparing the tooth to accept the crown. Then an impression is made of the tooth for use in fabrication of the crown at a dental laboratory.  While the crown is being fabricated, a temporary crown is worn. At the second appointment the temporary crown is removed and the permanent crown is adjusted as needed, then cemented in place.  A crown can be made of gold, porcelain over a metal alloy, or an all-ceramic material.

Bridges are use to fill spaces caused by missing teeth.  The bridge is held in place by the teeth adjacent to the space being filled.  A bridge can be fabricated with the same material as used for crowns and is constructed in a similar manner as a conventional crown.
