 A crown ("cap") is a tooth-like covering placed over a carefully prepared preexisting tooth. Crowns serve many functions, such as to strengthen, restore or improve the appearance of your natural tooth. For example, a crown can support the tooth when there is no longer sufficient tooth structure left to place a filling. Crowns may also be used to protect the structure of a tooth that is fractured or broken, and can be attached to bridges or dentures.
