For root canal treatment and wisdom tooth extraction, both operations are performed under anesthesia in current oral medical practice, so neither operation is painful at present. It should be noted that the extraction of wisdom teeth is relatively traumatic, and the pain will generally occur about an hour after the extraction of wisdom teeth, because the anesthetic injected during the extraction is gradually losing its effect, and the physiological pain occurs due to the trauma of the extraction, which can be tolerated by most patients. If you cannot tolerate it, you can consider applying relatively basic pain relief and analgesic drugs to control the pain, such as ibuprofen, aspirin, etc. On the contrary, root canal treatment, except for the application of anesthetics during the operation, generally does not have obvious pain after the operation.
