Crowns

A crown is a restoration that fits over the remaining part of you tooth making it resilient and giving it the look of a real tooth. Crowns can be used to restore teeth that have been broken or that have been weakened by decay. A crown may also be the ideal solution if you have a discoloured filling and you would like to improve the appearance of the tooth; or if you have had a root filling you may need a crown to protect what is left of the tooth.

Bridges

Bridges are ideal for people only have one or two teeth missing and do not want a denture. Bridges can be made by crowning the teeth on either side of the gap and attaching a false tooth in the middle. They are fixed in the same way as crowns and like crowns there a number of options available from all-ceramic or all-porcelain to metal and porcelain fused to metal bridges.

Why do a tooth need to be crowned?

The various reasons for doing a crown are :

  • When a tooth is badly broken down, a normal filling may not be strong enough for chewing
  • The tooth had root canal treatment done previously
  • To improve the appearance and/or contour of a tooth that is discoloured, mis-shaped or out of alignment
  • The tooth is under heavy chewing force, has cracked, or needs protection from wear and tear

How is a crown done?

Your dentist will do a thorough examination and diagnosis to determine if a crown is needed. The tooth is trimmed to make space for the crown and moulds are taken for the crown to be custom made in a dental laboratory. When the crown is ready, it is firmly cemented over the tooth

What are crowns and bridges made of?

They can be made of full ceramic, full metal or a combination of porcelain and metal. For the metal portion, there are also various options available depending on the amount of gold content of the alloy. The material will perform well when they are used for the right indications.
