What to Know About a Root Canal Procedure?


A root canal procedure is used to remove bacteria from an infected root canal. It is used to save the natural tooth. During the procedure the inflamed pulp is removed from the tooth and the interior of the tooth is thoroughly disinfected and cleaned prior to being filled and sealed.

There is soft tissue within the tooth that contains connective tissue, nerves, and blood vessels. This pump is covered by a hard layer that is called dentin and this is further covered with white enamel. The connective tissue within can help the root of the tooth grow when it is developing.

But once the tooth is fully developed, it can still survive the removal of the pulp because there is tissue surrounding the tooth that can nourish it. A root canal treatment is very effective and it is a relatively painless procedure. Before you are required to undergo the treatment, the dentist will take several x-rays of the infected tooth to get an idea of the level of damage that has been done and what the best way of approaching a solution is. A local anaesthetic will be administered for a root canal but if the tooth has died then this will no longer be required because the sensitivity is not there.   

To ensure the tooth is kept dry during the procedure, a rubber sheet will be placed around the tooth. The tooth will be opened through the crown by using a drill and this will allow the dentist to access the soft tissue or the pulp. The infected pulp will be removed after this. Some people tend to have dental abscesses and they can be drained at this moment as well. Once the pulp has been removed, the root canal is enlarged using files. This creates a space that will allow the dentist to fill it. This is the stage of the procedure that can take the most time.

This may take several hours or if it cannot be done in a day, there will be several days of filling the cavity. You will have to visit the dentist several times for this procedure. The length of the procedure depends on the number of roots that the tooth has. The canines and the incisors only have a single root canal but the molars and premolars have two or three roots that contain one or two root canals. So the latter will require more time for the procedure.

When the treatment is done over several visits, between each visit medicine will be put in the cleaned canal to remove any bacteria. A temporary filling will be used to seal the tooth. Some patients will receive antibiotics if there is swelling or fever as a result of the procedure. The temporary filling will be removed and the root canal filling will be inserted in the final stage of the procedure. The tooth will be sealed to prevent any infection from occurring again. You can place a crown on top of the tooth to ensure that it will not break.
