What types of bridges are there?

Besides traditional bridges, another popular design is the resin bonded or "Maryland" bridge, primarily used for the front teeth. This is usually the most economical choice when the abutment teeth are healthy and don't contain large fillings. The pontic is fused to metal bands that can be bonded to the abutment teeth with resin cement and hidden from view, reducing the amount of preparation on the adjacent teeth.
A cantilever bridge may be used if there are teeth on only one side of the span. This involves anchoring the pontic to one side over one or more natural, adjacent teeth. If there are no adjacent teeth to act as anchors, your dentist may recommend an implant-a metal post that is surgically imbedded into the bone and capped with a crown as an abutment.
In some cases where the span is large, your dentist may recommend a removable partial denture or even an implant-supported prosthesis.

What procedures are involved?

For a traditional fixed bridge, the first appointment consists of the dentist reducing the adjacent abutment teeth that will act as anchors. Impressions are made, from which a metal framework, including the pontic, is created. By the second appointment, the final bridge is fitted over the teeth.
The total treatment time is usually between two or four weeks, depending on the type of bridge. However, because it is often difficult to match the natural shade of your teeth, the treatment time may be longer.

How do I care for a bridge?

With a bridge, it is more important than ever to brush, floss and see your dentist regularly. If you do not control the buildup of food debris and plaque-the sticky film of bacteria formed from food acids-your teeth and gums can become infected, requiring further treatment and resulting in possible loss of the bridge. Your dentist may also recommend using floss threaders that help remove bacteria from hard to reach spaces between the bridge and adjacent teeth and gums.
If you maintain optimal oral hygiene care, you can expect your fixed bridge to last as many as 8-10 years, or even longer.
