When root canal treatment or endodontic treatment is necessary your dentist should inform you about the procedure. You will be informed about the entire protocol and the duration and number of visits expected until therapy is completed.
There are many reasons for root canal treatment. In most cases, the main reason is pulp or periradicular tissue infection, but sometimes, due to prosthodontic rehabilitation, some teeth need to be edodontically treated. Whatever the cause is, the essence of the procedure is pretty much the same. The main idea is to remove the pulp tissue and the infection from the pulp chamber and root canal system, which is followed by obliteration of this empty space with adequate filling materials.
