During a root canal, a dentist may have two options that you will need to settle before the procedure. You will either be given anesthesia or sedated for the root canal. The area is prepared, and the dentist takes an X-ray of the infected tooth to see how deep the cavity is. After that, the tooth is scrapped, and the decayed part is removed. Dentist use needles of various lengths and thicknesses to extract the pulp that contains nerves.
If conscious then you can feel the needles scrap against the structure of the tooth. Then another X-ray is taken to see whether the pulp has been completely removed from the tooth. The dentist may need to extract if the tooth is still vital. Generally, the patients do not feel any pain during the procedure.
After that, the dentists place the filling in the space. A temporary filling is placed for a few days before a more permanent filling in place in the treated tooth.
