How successful are root canals?

If properly performed by a dental professional, a root canal treatment will successfully remove the diseased pulp and restore the tooth.

During a root canal, the dentist or endodontist opens the crown of the tooth and removes the pulp tissue. The root canal is cleaned to remove bacteria and then enlarged, shaped, and filled with medications that prevent infection. A temporary filling is put inside the opening of the crown to protect the tooth. This procedure can take from one to three visits to complete. After the root canal is finished, a crown is fitted over the tooth to seal it, which prevents food, debris and bacteria from entering the tooth.

A tooth restored during a root canal could last a lifetime, as long as you continue to care for your teeth and gums. As long as the root(s) of a treated tooth are nourished by the tissues around it, your tooth will remain healthy.
