Dental Bridges
A bridge, or “fixed bridge” is a restoration that replaces one or more missing teeth. There are several types of bridges, but typically each end of the bridge is anchored by crowns over the abutting teeth. These crowns are attached to pontics (“fake teeth”), and together they fill the space created by the missing teeth. The bridge is held firmly in place by the abutment teeth and cannot be removed. Bridges may use implants as the abutment supports. Bridges are required for filling space left by missing teeth, replacing a removable partial denture, restoring chewing and speaking ability, and preventing remaining teeth from drifting out of position. Bridges are made from a variety of materials including porcelain and metal, usually a gold alloy. The materials have relative benefits and drawbacks, balancing strength, durability and esthetics.
The procedure for the bridge usually involves two appointments. The first appointment involves removing any decay or old filling material on the abutment teeth, then shaping the teeth and taking an impression to provide a mold to the dental laboratory. The patient leaves the appointment with a temporary bridge or individual temporary crowns. About two weeks later, at the second appointment, the temporaries will be removed and the new bridge carefully fitted. When the bridge has been cemented in place, there is often a short-term feeling of pressure from the adjacent teeth. The bite should feel comfortable. Maintenance of bridges is the same as maintaining all teeth; brushing and flossing with regular check-ups. Patients will be instructed in the use of a floss threader to clean under the bridge. Excessive force can chip or crack porcelain and natural teeth alike.
In each instance, Drs. Black or Itagawa consult with the patient to make the best treatment choice for their particular needs.
