A crown is a 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 an 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 filling that will need a crown to protect it.
