Root Canal (Endodontics)

Root Canal, or endodontics, is the process of removing the nerves from the roots of a tooth. A root canal is often necessary to save an infected tooth. If an infected tooth is left alone for a long period of time, an abscess can form. An abscess will show up on an x-ray as a dark spot below the apex of the root. This is actually bone loss in the jaw. It is very important to catch this problem before it deteriorates too far.
Why do I need a root canal?
There are a number of reasons why one of your teeth may need a root canal. These include but are not limited to:
-
A very deep cavity that extends into the nerve.
-
A trauma to the tooth that exposes the nerve.
-
A crack in the tooth that extends into the nerve of the tooth.
Signs or Symptoms you may experience:
- Moderate to severe lingering toothache pain when drinking hot or cold liquids or foods.
- Moderate to severe pain when biting on a tooth.
- Sensitivity to tapping or pressure on the tooth.
- Toothache that wakes you up in the middle of the night.
- A pimple on your gum that may release pus or blood.
- Radiating pain from one area of the mouth to another.
Endodontic treatment can often be performed in one or two visits and involves the following steps:
-
The endodontist will examine the tooth, take x-rays and discuss treatment. The endodontist will administer local anesthetic to numb the tooth. After the tooth is numb, the endodontist places a small protective sheet called a "rubber dam" over the area to isolate the tooth and keep it clean and free of saliva during the procedure.
-
The endodontist makes an opening through the top, or biting surface of the tooth. The doctor will then determine a working length of each canal. Each canal is then cleaned and shaped in preparation for the filling material.
-
Once each canal is prepared, it is filled with a biocompatible material called gutta percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening and will be removed by your dentist before the tooth is restored.
-
After the endodontist completes the root canal, you must return to your dentist to have a crown or other restoration placed on the tooth to protect and restore it to full functions.
If the tooth lacks sufficient structure to hold the restoration in place, your dentist or endodontist may place a post inside of the tooth.
