Crowns known as “caps” are used to cover the existing tooth in order to protect it from breaking. They are usually indicated in cases where there was an existing filling in the tooth that needs to be replaced but is too large to simply place another filling. Also, a crown is typically placed whenever a tooth has had a root canal. Root canals leave the tooth brittle and prone to fracturing. Crowns can be full porcelain, porcelain fused to a metal, or full metal.
A Bridge is an appliance used to replace one or more missing teeth. It is permanently cemented into the mouth and cannot be removed. Most bridges are made out of a fake tooth (or teeth) held together by 2 crowns that “bridge” the gap of the teeth. A bridge is often a great solution for the replacement of missing teeth.
