Root canal treatment can be very painful

The root canal treatment is usually done without significant pain. If the tooth is suffering from acute or chronic pulpitis, the first visit to the root canal will be under local anesthesia. The local anesthesia will take effect and the patient will not feel pain. We will open the pulp again and then release nerve killing drugs to kill the nerve. Normally, there will be no significant pain response. Root canal preparation, root canal irrigation, root canal dressing, root canal filling after nerve killing will not show pain reaction. If root canal treatment is done because of acute or chronic periapical periodontitis, there will be no obvious pain reaction during the whole treatment process. Moreover, root canal treatment is actually done to relieve the pain reaction of acute inflammation, so it will not cause obvious pain, but will obviously reduce pain.
