Previous Next 6 of 7

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. It 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.
