Root canal therapy is used to alleviate pain.
Most people who have root canal therapy admit they did not experience any pain during the appointment and felt better afterward. Having root canal treatment on a tooth does not mean that the tooth will need to be pulled out in a few years. Once a tooth is treated, it almost always will last the rest of your life .
Root canal treatment is just a special kind of filling, deep into your tooth's roots. A local anesthetic is often used to numb the area of your mouth and ensure the procedure is pain-free. The doctor will then make a small opening in the top of your tooth in order to remove the pulp from inside your tooth. The tooth is then cleaned out and shaped to a form that will receive a filling later.
