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, or a broken tooth. The crown restores the tooth and protects it from further damage. Crowns can also be used to cover a discoloured or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth.
A bridge is a dental restoration that replaces one or more missing teeth. It extends across an area that has no teeth and is typically made up of an artificial tooth fused between two crowns. The bridge is held firmly in place by your own teeth on each side of the missing one(s) or by dental implants. A bridge is cemented in place and cannot be removed.
