Slide show: Root canal treatment

The final stage of the root canal is restoring your tooth. Because the tooth typically has a large filling or is weakened from extensive decay, it needs to be protected from future damage and returned to normal function. This is usually done by placing a crown — a realistic-looking artificial tooth. A crown is made of gold, porcelain or porcelain fused to metal. Crowns made of porcelain or porcelain fused to metal can be tinted to match the color of your other teeth. Sometimes, a metal post must first be inserted in the tooth for structural support and to keep the crown in place. Ask your dentist or endodontist about other restoration options.
