Filling the root canals

After the tooth has been cleaned out and dried, it's time to fill the inside of the tooth, including the empty pulp chamber and root canals. You may not need more numbing medicine for this step. If you had a temporary filling, it's taken out to get inside the tooth. First, a sealer paste and rubber compound is used to fill the root canals. After this, a dental filling is placed to protect the root canals from saliva.
