What is a crown?

A crown is a cap that is placed over a tooth and held in place by dental adhesive or cement.

Crowns are used for several reasons:

  • as a protective cover for badly decayed teeth or fractured teeth
  • as a permanent restoration for teeth with large fillings
  • to improve your smile where teeth are discoloured, irregularly shaped or have gaps.

What are crowns made from?

Crowns can be made from a variety of materials. They can be made from ceramic or metal alloys. A combination of metal and ceramic is also possible to maximise strength and simulate the appearance of natural teeth.

How long do crowns last and how do I care for them?

Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease.

Ceramic on the surface may chip or fracture. Avoid chewing excessively-hard substances like ice or bones. Daily brushing and flossing are essential for maintaining good oral health as well as keeping the crown trouble-free. The most vulnerable portion of the crown is the margin or the junction between tooth and crown.

Regular check-ups will enable your dentist to detect any problems with your crown and recommend necessary treatment.

What are bridges made of?

Bridges are usually made of a precious metal. If the bridge will show, porcelain is then bonded to the base.

Are bridges expensive?

Although a bridge may seem costly they can be a wise investment that will give many years of good service. It will also improve your appearance and bite. A bridge uses the considerable skill of the dentist and technician, and in this way, it's similar to ordering a piece of hand-made jewellery.

How do I look after my bridge?

You need to clean your bridge every day, to prevent problems such as bad breath and gum disease. You also have to clean under the false tooth every day. Your dentist or hygienist will show you how to use a special floss, as a normal toothbrush cannot reach.
