A bridge, also known as a fixed removable denture, is made to replace one or more missing teeth.
Bridges can be supported in two different ways:
- By natural teeth
- By implants
A traditional bridge is made by creating a crown for the teeth on either side of the space and placing a false tooth or teeth between the crowns. The crowns, sometimes called caps, can be supported by natural teeth or by implants. The false tooth or teeth are attached to the crowns and fill the empty space.
If the teeth receiving the crowns are healthy and strong, they probably will not need root canal therapy. However, parts of the teeth will be removed to make space for the crowns. Traditional bridges are made either of porcelain fused to metal (PFM) or ceramics.
There are other types of bridges as well. A cantilever bridge is held in the mouth by one or more crowns on only one side of the space where a tooth is missing. A Maryland bonded bridge consists of a metal framework with “wings” on each side. The wings are bonded to the back of your existing teeth. The false teeth are also bonded to the framework. This type of bridge is also called a resin-bonded bridge or an acid-etched bridge.
Getting a bridge requires at least two visits, but often more. At the first visit, we will prepare the teeth and covers them with a temporary bridge. The impressions of the teeth also will be taken.
The bridge is placed at later visits. Statistically, bridges last 5 to 10 years. A major reason bridges fail is that new cavities develop on the supporting teeth. These cavities occur because of poor oral hygiene. With proper hygiene, which includes flossing your teeth under the bridge, they will last 10+.
