Crowns

A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. a crown is sometimes known as a ‘cap’.

 

 

 

 

 

 

 

 

 

 

 

 

Crowns are the ideal restoration for teeth that have been broken, or have been weakened by decay or a very large filling. a crown could be used for a number of other reasons, for instance:

  • you may have discoloured fillings and would like to improve the appearance of the tooth

  • you may have had a root canal filling which may need a crown to protect what is left of the tooth

 

Crowns are made of a variety of different materials and new materials are continuously being developed. Some of the widely used crowns are listed below.

  • Porcelain bonded to precious metal - this is what most crowns are made from. A precious metal base has layers of porcelain applied over it.

  • Porcelain crowns - these crowns are made entirely out of porcelain and are not as strrong as bonded crowns, but they look very aesthetic and are mostly used for the front teeth.

  • All ceramic crowns - this modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. It is suitable for use in all ares of the mouth.

  • Gold alloy crowns - gold is used with other metal alloys to increase its strength and makes it a very hardwearing restoration.
