Crowns (click on images to enlarge)

 

A crown may be required when an ordinary filling cannot be used with confidence for the long term benefit of the tooth. for example:

  • When a tooth has been extensively damaged by decay

  • When a heavily filled tooth fractures or shows signs of possible fracture, like cracks in the enamel

  • When a tooth has been badly damaged in an accident

  • After root canal treatment when the remaining tooth would be vulnerable to cracking or fracture

  • When a tooth has worn down badly over time

In all these cases, a crown is often the best way to save a tooth and strengthen it. a crown fits over the existing natural tooth, and acts like a brace to hold the remaining tooth and filling together and prevent further breakdown of tooth.

 

What is a crown made of?

Crowns are usually made out of porcelain over a gold alloy base. They can be made out of porcelain and zirconia.
Porcelain is strong and can be made to match the colour of the natural teeth. Porcelain is also resistant to staining.

How is it done?

  • The tooth to be crowned may need to be filled or repaired first.

  • Then the tooth is shaped by making it smaller by 1 to 1.5 millimetres. This is to allow sufficient room to place the crown and thus restore the tooth to its proper form. This procedure is usually done with a local anaesthetic so that it is completely painless.

  • A mould or impression of the prepared tooth is taken and sent to our Dental Laboratory, where a replica of the tooth is made.

  • On this replica, the laboratory constructs the crown to the specifications of the dentist. The aim being to recreate the form of the tooth with a strong, precision fitting crown that will seal the underlying tooth and to protect it from possible fracture.

  • To protect the reshaped tooth, a temporary crown is fitted with temporary cement. As a temporary crown is not as strong as the final crown, you should chew on the opposite side of the mouth and avoid sticky or hard foods.

  • Once the crown is ready, the dentist will fit it onto the tooth and finally cement it in place with permanant dental cement.

 

A crown that is well designed, constructed, and fitted is a fixed permanent restoration of the broken down tooth, and should feel comfortable and natural in your mouth.

Cost – From $1500.00 each

Possible Complications

  • Tooth breakage during preparation – may require repair but is usually determined before commencement

  • Infection of the nerve (pulp) or gums – may lead to the tooth requiring additional procedures like root canal treatment

  • Pain or discomfort – usually only for a short time after the preparation

  • Altered feeling

  • Loosening of the crown

  • Allergic responses to some materials used
