We can replace one or more teeth in many ways. A fixed bridge is one of the strongest and best looking alternatives. The teeth adjacent to the missing teeth are prepared for crowns so they line up properly and a bridge is made to replace the missing teeth [we call the replacement teeth pontics] as well as cover over the anchor teeth [we call those teeth abutments]. Fixed bridges give you back full chewing function in they will look great and last for many years.
When a tooth is badly broken down due to decay or fracture we place a crown over the tooth to surround it, strengthen it and restore full function back to the tooth. Also, after a tooth has had root canal therapy it will often need a crown to hold things together and avoid a fracture that could otherwise doom the tooth.
