CROWNS & BRIDGES
A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown may be an option to repair a broken tooth, or strengthen a weak tooth due to decay or root canal treatment. In root filled teeth it may be necessary to insert a post into the tooth before placing a crown to give more support and strength.
A bridge is made up of two or more crowns for the teeth on either side of the gap with a solid piece in the middle (the bridge).
