Crowns (or "caps" as they are sometimes called) fit over your teeth and help protect them from breakage. They can be made entirely from gold, which creates a very strong restoration, or from porcelain, which can make a very beautiful restoration. Often we can combine gold and porcelain – that is a gold crown with porcelain over the outside, which creates a strong and very life-like restoration.

Crowns can be used to improve the appearance of teeth as well as strengthening teeth and creating an improved biting surface for better occlusion. Crowns are often used to support "bridges" which are sometimes used to replace missing teeth.
