A fixed bridge replaces a missing tooth or teeth. It is called a fixed bridge because it is not removable. A bridge is a structure, supported by teeth on either side of a space. It spans the gap between teeth, just as a bridge spans a river.
The first step is to prepare the supports for the bridge. Replacement crowns are placed over existing teeth as supports for a bridge. The dentist pares down the teeth on either side of the gap, and takes an impression of the prepared teeth. This is then sent to the dental technician where the bridge is made. The technician will make a replacement crown for each prepared tooth. These crowns are joined to an artificial tooth, which replaces the missing tooth. The dentist will then cement the completed bridge over the prepared teeth. The dentist will make and install a temporary acrylic bridge that will protect the teeth and prevent sensitivity. You can eat normally with a temporary bridge. It will also look good.
The base or framework is made of precious or non-precious metal to which tooth-colored porcelain is fused. Since the development of new stronger ceramic materials, bridges can now be made entirely of porcelain.
The procedure is not painful, because a local anesthetic is used during the paring of the teeth, and the taking of the impression. It is seldom necessary to take an analgesic for pain relief after the treatment.
Sensitivity to hot and cold sometimes occurs after the bridge has been cemented, but this is usually temporary.
Fixed bridges can be made to look natural and to match the adjoining natural teeth. A bridge in the front of the mouth will restore and even improve the smile.
Eating with a fixed bridge should be as comfortable as with natural teeth.
Fixed bridges have been used successfully to replace one or more missing teeth. They can last for many years.
