Crowns and Bridges

What is a Crown?

A crown is used to restore a tooth which has a very large restoration or has had root canal treatment

Very large restorations make you tooth more likely to fracture. A crown covers the whole of you tooth and protects it from chewing forces and hard foods which may cause the fracture.

If you have had root canal treatment your tooth will be more brittle. The crown will not only protect the tooth from fracture but may restore function if you have lost a lot of tooth structure due to decay.

What is a Bridge?

fpp.jpg (33108 bytes)A bridge replaces one or more natural missing teeth, thereby ‘bridging’ the space between two teeth. Fixed bridges are cemented into place next to “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 (see diagram) that are cemented to abutment teeth.

Who should get a bridge?

If you are missing any teeth and are committed to maintaining good oral hygiene practices, you may be a good candidate for a bridge. A bridge is the most natural choice to fill the space in your mouth left by missing teeth. 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 not only correct an altered bite, improve your chewing ability and speech, but they also safeguard your appearance by preventing the collapse of your facial features that can cause premature wrinkles and age lines.

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 or third appointment, the final bridge is fitted over the teeth.

The total treatment time is usually between two and four weeks, depending upon 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 acids in foods — your teeth and gums can become infected, requiring further treatment and resulting in possible loss of the bridge.

We recommend using super floss and piksters that remove plaque from hard to reach spaces between the bridge and adjacent teeth and gums.
