If your tooth is damaged but not lost, a crown can be used to restore its shape, appearance, and function. You may need a crown if you have a root canal, a large filling in a tooth, or a broken tooth.

A crown also called a cap, is a hollow, artificial tooth used to cover a damaged or decayed tooth. The crown restores the tooth and protects it from further damage.  A crown can also be placed on top of implant to provide a tooth like shape and structure for function. Porcelain or ceramic crowns can be matched to the colour of your teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are stronger than porcelain and may be recommended for back teeth.
