The root canal treatment includes the dentist drilling a hole through the chewing surface of the tooth to achieve the nerve in the tooth that's known as the pulp. The pulp extends down the tooth's root and has to be removed so that disease can be prevented or treated. 

Thin metal wires are placed into the tooth down to the bottom of the main root canal and the pulp is extracted. This keeps it from becoming irritated in the long run and causing pain which could result from an illness, chewing gum or sensitivity to hot and cold meals and beverages.

This measure will prevent germs from making it back into the cavity and causing potential problems for the individual. The gum is then replaced with a temporary filling that remains for at least fourteen days prior to a permanent filling or a crown is placed in.

What is the process like?

When you sit down in the seat for the process, the dentist will typically give you a brief summary of what the method consists of. Then, the regions where the Novocain is going to be injected are rubbed with topical gel that gently numbs the area where the need is going to be injected. 

Then the shots are given, usually between 2-4 injections, and you will be left to wait for a couple of minutes while the anesthetic works its magic. After about 15 minutes, the physician will return and start working.
