A root canal is a procedure 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. In absence of the treatment, the tissue surrounding the tooth will become infected and abscesses may form.
Root canal is the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth's nerve lies within the root canal. A tooth's nerve does not serve any vital function except providing sensory function.
The first step in the procedure is to take an X-ray to see the shape of the root canals and determine if there are any signs of infection in a surrounding bone. Your dentist will then use local anesthesia to numb the area near the tooth. Anesthesia may not be necessary, since the nerve is dead.
Dentist will place a rubber dam to keep the area dry and free of saliva during treatment. After this, an access hole will then be drilled into the tooth. The pulp along with bacteria, the decayed nerve tissue and related debris is removed from the tooth. The cleaning out process is accomplished using root canal files. A series of these files of increasing diameter are each subsequently placed into the access hole and worked down the full length of the tooth to scrape and scrub the sides of the root canals. Water or sodium hypochlorite is used periodically to flush away the debris.
Once the tooth is thoroughly cleaned, it is sealed. Some dentists may opt to wait a week before sealing the tooth. If the root canal is not completed on the same day, a temporary filling is placed in the exterior hole in the tooth to keep out contaminants like saliva and food.
During the next visit, a sealer paste and a rubber compound called gutta percha is placed into the tooth's root canal. To fill the exterior access hole created at the beginning of treatment, a filling is placed.
The final step may involve further restoration of the tooth. Because a tooth that needs a root canal often is one that has a large filling or extensive decay or other weakness, a crown, crown and post, or other restoration often needs to be placed on the tooth to protect it, prevent it from breaking, and restore it to full function. Your dentist will discuss the need for any additional dental work with you.
