Dental Crowns

A crown is a great way to improve the appearance of a broken or decayed tooth. It is simply a cap that is cemented over the damaged tooth, making it blend in with your adjacent teeth.

Crowns can be made from gold, porcelain or ceramic depending on your preference.

Dental crowns have many uses:

To protect a decayed tooth from breaking
To cement together parts of a cracked tooth
To restore the appearance of a worn down tooth
To support a natural tooth with a large filling, when there is not much tooth structure left
To secure a dental bridge in its place
To cover discoloured teeth and dental implants

What Types of Crowns Are Available?

Metal crowns may be made of materials including alloys of gold or other non-precious medal based alloys. These type of crowns require the least amount of tooth substance to be removed because the metal base is in thin section. Metal based crowns are very good at taking biting forces and are very good crowns to be placed in the back molar regions where aesthetics are not so important but chewing strength is.

Porcelain fused to metal crowns are very good choice for both anterior and posterior teeth. They can be colour matched to one’s own existing teeth.

Metal free all ceramic crowns represent the ultimate in high aesthetics and superb looks. They are a very good choice for front teeth although they are not as strong as porcelain fused to metal crowns.

A crown is normally made over two visits.

At the first visit the tooth is prepared and an impression taken of that prepared tooth. The crown is made by a dental technician after the impression of the prepared tooth is sent to a dental laboratory.
At the second visit the crown is cemented onto the prepared tooth. In between the preparation and cementation visits a temporary crown is made to preserve form and function.
