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 an ideal way to repair 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 example:
Crowns can be made of a variety of different materials and new materials are continually being introduced.
This is what most crowns are made from. A precious metal base is made and then porcelain is applied in layers over it.
These crowns are made entirely out of porcelain and are not as strong as bonded crowns. But they can look very natural and are most often used for front teeth.
These crowns look very natural and can be used anywhere in the mouth.
This modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. Therefore it is suitable for use in all areas of the mouth.
Gold is one of the oldest filling materials. Today it is used with other metal alloys to increase its strength, which makes it very hardwearing. These crowns are silver or gold in colour.
