Previous Next 5 of 7 Filling the root canals

After cleaning and drying, it's time to fill the interior of the tooth — the empty pulp chamber and root canals. You may not need additional anesthetic for this step. If you had a temporary filling placed, that will be removed to allow access to the inside of the tooth. A sealer paste and rubber compound is used to fill the tooth, followed by a dental filling to make sure the root canals are protected from saliva.
