Missing one or more teeth is common for many people. The ADA reports that on average adult patients may have three missing or decayed teeth. Fortunately, there are a number of solutions to replace missing teeth, including dental bridges.
A bridge may be used to restore an area with one or more adjacent missing teeth. A bridge has two primary components. The abutments (or supports) for the bridge are created by placing a crown on either a natural tooth or an implant. The synthetic tooth that replaces the missing tooth is called a pontic.
There are four main types of dental bridges:
Traditional Dental Bridge – The existing teeth are crowned with one or more pontics between and held in place by the crowned abutments. The crowns are cemented onto the teeth adjacent to the missing teeth to create a support structure or “bridge” for the missing teeth.
Cantilever Bridge – Similar to a traditional bridge, the structure is supported on only one side instead of both sides. This can cause the restoration to act as a “lever” and may create additional stress on the supporting tooth, causing it to be more likely to loosen or fracture.
Implant Supported Bridge – A dental implant is placed to provide support for one or both sides of a dental bridge. This popular option can provide a very secure restoration and is particularly helpful when there are several adjacent missing teeth.
Maryland Bridge – This bridge is supported by a metal structure which is cemented onto the back of existing teeth. While not as strong as a traditional bridge, it can preserve the tooth structure of the adjacent teeth by avoiding the use of crowns for the abutments. It may not stay in place when heavy forces are placed on the restoration (such as biting and chewing) and does add pressure to the supporting teeth.
