Do I Need a Root Canal?

People often have the misconception that root canal therapy is a painful experience and mistakenly believe that having an infected tooth removed is a preferable choice. Also known as endodontic (“endo” – inside; “dont” – tooth) treatment, a root canal will relieve the severe pain that is caused when the tooth nerve has become inflamed. Unfortunately, extracting an infected tooth can introduce many additional problems that could be avoided with a root canal.

A root canal may be necessary if a deep cavity or trauma to the tooth has occurred, causing the inside pulp to become infected or inflamed. Often, pressure develops inside the core of the tooth which is the source of sharp, lingering pain when biting down or when exposed to temperature changes, particularly from hot foods and liquids. Sometimes, a dull ache may be present and the gum may be sensitive to pressure. Left untreated, an abscess may develop and infection can spread from the tooth to the surrounding bone, and even into the bloodstream.

Immediate dental treatment for a suspected endodontic infection is always the best course of action, and the treatment is relatively pain free and is performed under a local anesthetic administered by the dentist. First, the dentist will have to x-ray the suspicious tooth to diagnose the problem and will sometimes test the tooth to determine whether the nerve is in the process of dying. Once it has been determined that an infected tooth requires a root canal, and the tooth and surrounding area are numb, a small opening is made into the tooth, just as if one were having a filling placed. The infected, dying nerve and blood vessels are removed and the root canals are smoothed, cleaned, disinfected and filled with a rubber material. Some patients feel slight tenderness around the tooth for a day or two, but generally aspirin or ibuprofen will provide sufficient relief. After the nerve has been removed a tooth is no longer living, and the lack of blood supply causes it to become brittle over time. Your dentist will almost always advise you to have a crown placed on an endodontically treated tooth to protect it.

Most of the time a root canal can be performed in a single appointment and the crown will require two more visits to complete. The end result is that you will have kept your natural tooth and restored it to full function. Because bone loss and shifting of the remaining teeth often result when a tooth is extracted, the root canal avoids these complications as well.If you are confronted with the recommendation to have root canal treatment, or if you are experiencing unexplained pain when chewing or to temperature, don’t hesitate to inquire about your options or ask for further information about endodontic treatment to restore your smile and comfort.
