During a root canal treatment, the dentist will numb the tooth or area using local or injectable anesthetic, depending on the anxiety level as well as pain tolerance of the patient. A piece of rubber is slipped over the tooth to isolate it from neighboring teeth. The tooth is then drilled and a hole created through which the dentist will be able to remove infected or decayed material from inside the tooth. The tooth is then flushed with antiseptic solution.

The tooth will be refilled with a sealer paste or rubber compound, and the original drill hole is filled using typical dental filler materials. At this time, additional restoration of the tooth may be initiated, or a crown fitted to help protect the tooth as well as preventing it from breaking and help restore full function.

If you experience these things then your dentist did the root canal treatment.
