-What is a crown?

A crown - sometimes called a "cap" - is a tooth-like covering placed over a carefully prepared existing tooth. Used to strengthen, restore or improve the appearance of your natural tooth, a crown is placed on an individual tooth much like a thimble over your finger. In addition to being used to strengthen a tooth to accommodate the attachment of a fixed bridge, crowns serve many functions. One of the most common is to 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.
