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. Crowns can also be used to cover a discolored or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth.
Crowns are designed to look and feel like real teeth. As with your original smile, care must be taken to avoid tooth fracture and with good oral hygiene, your crown will last longer.
