What are they?

When teeth are missing there are a number of ways we can replace those teeth. A great way to do this is using a Composite bridge. A Composite bridge uses the teeth on either side of the space to replace the missing teeth. The Bridge is glued in permanently to the teeth on either side so it doesnt have to be removed. Composite Bridges are a new technology which does not have a lot of long term data to support them, it is therefore slightly experimental. However due to the fact they are relatively inexpensive and require little or no tooth modification before placement there is very little risk. ( they are most often done in comfort without local anesthetic)

When a tooth is lost 5 or more other teeth may drift so it is essential to place a replacement tooth as soon as possible. The space left from missing teeth may cause one of several problems. Teeth may drift into the space changing your bite, this changed bite may result in sore jaws, gum disease, or decay (due to more difficult hygiene).

How are they done?

Firstly, the parts of the teeth used to attach the bridge are carefully roughened. This is achieved by using a light acid which makes the tooth surface easy to bond to. A combination of Composite resin and nylon strips are placed in the space between the teeth where they are hardened and shaped. After a final polish the bridge is ready to be used straight away.
A fixed bridge is used to replace one or several teeth. The teeth on each end of the space are used as anchors (abutments). Bridges are not removable by the Patient.

Composite Bridges have many benefits over conventional Porcelain Bridges; They are Metal free, they are repairable, they are about 25% of the price, they do not directly damage the teeth on either side except for the minor collateral damage associated with any bonding process, they can be placed in one appointment.

The disadvantages are: no long term longevity studies have been done which makes them experimental in nature, they theoretically are more likely to decay the attached teeth in patients with poor oral hygiene, they are not as strong and probably wont last as long as Porcelain and they are more likely to develop staining.

Care for bridges

Brush daily all areas around the bridge. It is not possible to floss between the replacement tooth and the attaching crowns (it is made as a solid piece). In order to solve this problem - it is necessary to use a special type of floss to go under the replacement tooth and keep this area of gum tissue healthy.
