Crowns & Bridges

Crowns

A crown is a cover for a tooth which is decayed, damaged or has had recurrent fillings. A crown is usually made of porcelain, metal alloys or gold.

A dentist will remove any decay around the tooth to be crowned and also a small quantity of enamel. The tooth is then shaped into a base for the crown. The dentist will take an impression of the shaped tooth so that the crown will fit precisely into place.

The artificial permanent tooth is then cemented onto the shaped natural tooth.The artificial tooth will match the colour of the natural teeth and the shape of the crown will permit the gum tissue to return to normal position.

Bridges

Bridges are used as tooth substitutes which are attached to neighboring natural teeth. To secure a bridge, both the surrounding tissue and bone of the adjacent teeth must be healthy.

The bridge consists of one or more artificial teeth which are placed between crowns and fixed over the natural, neighboring shaped teeth (as above). There are two common varieties of bridges. A fixed bridge (pictured here) and a Maryland Bridge which uses metal clasps instead of crowns to attach to the natural teeth.
