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 ideal for restoration for teeth that have been broken, or have been weakened by decay or a very large filing .

A crown could be used for a number of other reasons,for instance:

- You may gave discoloured filings and would like to improve the appearence of the tooth

- You may have had a root filing which will need a crown to protect it

- It may help hold a bridge or denture firmly in place
