All about Crowns, Inlays, Onlays and Bridges

A crown is a full covering of the tooth.

The crown is constructed in a Laboratory, made from porcelain, porcelain bonded to metal, or gold, and is cemented over your natural tooth.

A crown may be required if a large amount of your tooth is missing or the remaining tooth structure is weak, has fractured or your tooth has had root canal therapy.

A crown can improve the strength and appearance of your teeth that may have large visible fillings or be discoloured.

Crowns can provide you with a new smile!

With routine maintenance as part of an overall treatment plan, crowns can be successful for many years and provide strong teeth for comfortable, dependable chewing.

An Onlay and Inlays are like a partial crown, usually over the top section of the tooth, and normally used only for the back teeth. They are used to replace sections of the tooth in cases where there is too much damage or decay and a filling would be deemed inappropriate. They are glued into place and are extremely strong - they can withstand the grinding pressures of back teeth.

A Bridge is similar technique to having a Crown, but allows the replacement of a missing tooth. If you have a missing tooth then the two adjacent teeth are crowned which enables the placement of a metal alloy structure between the crowns and an artificial tooth to fill the gap (hence the name 'bridge'). With the advancement of implant technology there is less demand for Bridges, however there are still circumstances where a bridge would be a favoured option.
