Endodontics (Root Canal)

What is a root canal treatment (endodontics)?

Back in the day, when the nerve of a tooth gets damaged or infected, the only treatment was to extract the tooth. However, by performing a root canal procedure, the damaged / infected pulp (shown in red in the following picture) is removed. By not removing the infected tooth, it prevents your other teeth from drifting out of line and causing jaw problems.

How is a root canal performed?

First, your tooth will be isolated by a rubber dam. After being numbed, an opening extending down into the pulp is made in the crown of the tooth. The pulp is removed and the root canal cleaned and shaped to hold the filling. At this point, the canal may either be permanently filled and sealed, or filled with a medication to reduce infection. The tooth may be placed with a temporary filling or left open to drain.

THe damaged pulp is removed.

 

At your next appointment, the interior of the canal is sterilized and then permanently filled and sealed. X-rays will be taken throughout this procedure to ensure the canal is smooth and free of infected pulp. Dr. Jaleel may recommend placing a crown on your teeth to help strengthen it.
