A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.

Root canal therapy (endodontics) can reclaim teeth after they have died. The most common causes of pulp death are physical trauma to the tooth, a cracked tooth, or a deep cavity. Sometimes the pulp is referred to as the "nerve."
If no treatment is done, the infection in the tooth and root can spread to surrounding area of the mouth and tissue spaces leading to swelling, pain and infection. Once the pulp inside a tooth becomes infected, serious complications can occur if not treated with a root canal.
A successful root canal can cause mild pain for a few days. This is temporary, and should go away on its own as long as you practice good oral hygiene. You should see your dentist for a follow-up if the pain lasts longer than three days.
Your restored tooth after root canal therapy could last a lifetime, if you continue to care for your teeth and gums. However, regular checkups are necessary. As long as the root(s) of a treated tooth are nourished by the tissues around it, your tooth will remain healthy.
A crown on a front tooth depends on the cause of the need of the root canal therapy. If the tooth had previous damage or is now a lot weaker because all of the pulp has been removed, then a dentist will often put a cap over it to keep it strong so that no further damage is done. Check our section for crowns and bridges for more information.
