Crowns and Bridge
A crown is used to entirely cover or “cap” a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Full Porcelain or ceramic and Porcelain bonded to metal crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys.
Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, an impression is taken to provide an exact mold for the crown or bridge. Using this impression, a dental lab then makes the crown or bridge, in the material the dentist specifies. When the permanent crown or bridge is ready, it is cemented over your prepared tooth or teeth.
Types of Crowns
- All ceramic
- Porcelain bonded to metal crowns
A bridge may be recommended if there are missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and Temporomandibular joint (TMJ) disorders. Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge.
