What is a bridge?
A bridge is a dental appliance that replaces one or more natural missing teeth, thereby "bridging" the space between two teeth.
Fixed bridges are cemented into place next to the "abutment" teeth - the surrounding teeth on either side of the space, or "span." Unlike removable partial dentures, fixed bridges cannot be taken out of the mouth by the patient. A fixed bridge is a device that typically consists of three units--a pontic (a false tooth) fused between two crowns that are cemented onto the abutment teeth.
Who should get a bridge?
If you are missing 1, 2, or 3 teeth in a row, with teeth at either end, you may be a candidate for a bridge. A bridge is the most common choice to fill the space in your mouth left by missing teeth. If left unfilled, this space can cause the surrounding teeth to drift out of position and can cause teeth and gums to become more susceptible to tooth decay and gum disease that can cause further tooth loss. Fixed bridges can correct an altered bite, improve your chewing ability, and improve your speech.
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. Photos may be taken to help the dental laboratory match the colour of your teeth. A plastic temporary bridge is made to protect your teeth between appointments.
At the second appointment, the temporary bridge is removed, and the real bridge is fitted over the teeth. The total treatment time is usually between two or four weeks, depending on the type of bridge.
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 your 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.
