Dental Crowns

Crowns are restorations that cover or cap teeth, restoring them to their natural size, shape, and color. Crowns are indicated when there is a need to strengthen teeth that are mechanically weakened

Crowns not only help appearance, but can also save a tooth that might otherwise be lost.

Dental Bridges

A dental bridge is a false tooth (called a pontic) that's used to fill the gap. Unlike traditional removable dentures, a dental bridge is permanent as it's anchored to the teeth at one, or both, sides using metal bands held in place by resin or cement. If well cared for, a dental bridge should last for 10 to 15 years.

There are three types of dental bridge: fixed, resin bonded, and cantilever. The type of bridge used will depend on the quality of the teeth on either side of the gap, as well as the position of the gap:

i) Fixed Bridges
With a fixed bridge, the false tooth, or pontic, is anchored to new crowns attached to the teeth either side of the gap. These crowns are usually made from porcelain with the new tooth made from either ceramic or porcelain. This forms a very strong bridge that can be used anywhere in the mouth.

ii) Resin Bonded Bridges
Sometimes called Maryland Bonded, these dental bridges do not involve crowning the adjacent teeth, so are useful where these show little or no previous damage. The new tooth is generally made from plastic and is attached via metal bands bonded to the adjacent teeth using resin. This type of bridge is particularly suitable for front teeth where stress is minimal, and the bond can be made out of view behind the teeth.

iii) Cantilever Bridges
These dental bridges are used where there is a healthy tooth only on one side of the gap. The bridge is anchored to one or more teeth on just one side. As a result, this type of bridge is generally only suitable for low stress bridges such as front teeth.
