What is a crown?
A crown is a full coverage restoration. One of our dentists may recommend a crown for a tooth which has been badly broken down or lacks structural strength. The crown will be designed to fully cover the tooth with either: metal, metal and porcelain, or all porcelain. We will need to remove a certain amount of tooth structure from all around the tooth and from the chewing or biting surface to allow enough room for the crown material to surround the tooth with adequate thickness for strength. Although a crown will fully cover the exposed part of the tooth, it still must be kept very clean as the bacteria which cause cavities can still collect at the edges of the crown and cause cavities/decay. A standard crown is designed to last anywhere from about 15 to 25 years, but the long-term success of a crown will also be based on how well it is maintained and the amount of wear that it receives.
