Crown and Bridge

What is a crown?

A crown is basically a manufactured tooth. It’s generally made of porcelain or ceramic that can be colour and texture-matched to your existing teeth. A crown can also be made of gold alloys for improved strength when replacing a back tooth. Often a metal crown will have porcelain bonded to the exterior to give it strength and a natural look.

What is a bridge?

A bridge is a prosthetic appliance that replaces missing teeth. Bridges are usually made of porcelain fused to metal in order to achieve both strength and a natural look.

How is a crown and bridge fitted?

Crowns are used when an existing tooth is damaged, fractured or weakened. The tooth is filed down and reshaped into a smaller size. Any decay is removed and the tooth structure is restored to support the crown. The crown fits like a cap over the newly shaped tooth and is cemented into position.

A bridge consists of false teeth rigidly attached between two crowns. The teeth on either side of the gap are prepared for these crowns and the bridge is cemented into place. In some cases, it’s possible to use implants to replace the missing teeth rather than using the existing teeth. Once a bridge is cemented into position, it looks and works just like natural teeth.

When is a crown or bridge required?

A crown can be used when:

• - a tooth is fractured or damaged

- too much decay has weakened a tooth

- a tooth is severely discoloured

• - a tooth is misshapen

A bridge can be used when:

A bridge is used to replace a missing tooth or teeth. It is also a possible solution when dentures are unstable, uncomfortable or aesthetically displeasing.

To find out if you’re a suitable candidate for a crown or bridge, it’s essential that you are assessed by a dentist. Once you explain to your dentist the result you would like to achieve, they will be able to tell you exactly what is, and is not, possible in your situation.

Crown and bridge care:

Once your crown or bridge is fitted, it’s important to maintain a regular and effective routine of oral hygiene. Brush and floss two to three times a day, taking extra care to floss around your crown. This will help avoid decay where the crown and the tooth join. Avoid sticky foods such as toffee and lollies, and do not use your teeth inappropriately – chewing pens, crunching ice, gnawing fingernails, etc.

A dental floss threader, which looks like a small bendy brush, can be used to clean under your bridge. There are also water jets on the market that will help keep your bridge clean.

Whether you have a crown or a bridge, the most important thing is to regularly visit your dentist for a check-up and clean. This way problems can be detected early, allowing them to be corrected before they become painful and expensive.
