A dental bridge is typically made of two crowns, and a set of false teeth between them, that bridges a gap created by one or more missing teeth. The crowns are the anchors to your bridge and are known as either anchoring teeth or abutment teeth. The teeth between the anchoring teeth can be either your natural teeth or dental implants. Bridges can be made from gold, alloys, porcelain or a combination of all three.

Types of Dental Bridges
There are four main types of dental bridges:
Traditional Dental Bridge
A traditional bridge has two or more crowns with filler teeth. The filler teeth are attached to one or more of the crowns, keeping your bridge in place. They are usually composed of porcelain fused to metal or ceramic.
A cantilever bridge is similar to a traditional bridge except it is supported on one side instead of two. It can cause the bridge to act like a lever creating stress on the supporting tooth. This type of bridge is more likely to loosen or fracture.
A Maryland bonded bridge, also known as a resin-bonded or Maryland bridge, is made of porcelain fused metal and supported by a metal framework. Metal wings on the side of the bridge are then bonded to your teeth. A Maryland bonded bridge is typically used to replace your front teeth.
Implant Supported Bridge
An implant supported bridge uses a dental implant to provide support for one or both sides of a dental bridge. This option is very popular because it can provide you with a very secure restoration. It’s also very helpful when there are several adjacent teeth that are missing.
