Bridges are false teeth, anchored onto neighbouring teeth. The false tooth is known as a pontic and is fused in between two crowns that serve as anchors by attaching to the teeth on each side of the false tooth – bridging them together.
If you have a missing tooth or more, a bridge is needed as a fixed replacement. They are usually created from porcelain and precious metal and fixed by taking impression of the surrounded teeth and then fusing the false tooth between two crowns that serve as anchors (by attaching them to each side of the false tooth- bridging them together).
There are three types of bridges:
1. Traditional fixed bridge
The most commonly used bridge, fixed bridges, cannot be removed. They consist of the tooth being fused between two porcelain crowns that are anchored on neighbouring teeth or implants.
2. Resin-bonded bridges or Maryland-bonded bridges
These are chosen when the teeth on either side of the missing tooth are strong and healthy. The false tooth is made of plastic and is fused to metal bands that are bonded to the adjacent teeth using resin that is hidden from view.
3. Cantilever bridges
These might be chosen if the missing tooth is at the front. Cantilever bridges are used when there are teeth present on only one side of the space, where the false tooth is anchored to one or more adjacent teeth on one side.
