A root canal treatment or therapy is a procedure wherein the pulp of the tooth is removed, cleaned for any abscess residue, disinfected and filled with composite filling. It is usually the last resort to save a tooth to be extracted directly – most likely for aesthetic reasons. After the tooth canal treatment, the tooth is still attached to the gums, but cannot be felt more, because it's already dead. Eventually, it will become brittle and darken like a death nail, and it will take a jacket to hold up after a few weeks or months.

There are many reasons why one should get root canal treatment. For one, if you do not want the aching tooth to remove, but you want to get rid of the unbearable pain he is causing, the dentist may suggest root canal instead of the traditional dental extraction (in which the tooth is picked directly on your gums).

Canal treatments are often expensive and should be used sparingly on teeth that only require treatment. Before any proceedings take place, the dentist will ask you first to get an X-ray of the affected row of teeth before the procedure begins. And before you hand X-rays your dentist, bring it to other dentists, you can also get advice from them if you really need root canal or not.
