There is no 1 definitive answer to the question of how many days after wisdom tooth extraction without pain. Just as an example of normal physiological pain after extraction, from not much pain after extraction itself, to having pain a week after extraction are normal post-operative conditions that would be seen in clinical practice. In general, the pain after wisdom tooth extraction is mainly related to the size of the extraction trauma. In the case of wisdom tooth extraction, it is relatively simple to remove the wisdom tooth by means of dental jaws and dental forceps. It is normal for a large proportion of patients to feel no significant pain after the anesthetic has passed. However, in the case of more complex wisdom teeth, such as those that are buried and obstructed, the extraction process involves gingival incision, flap and bone removal, which is more traumatic and takes longer, and there will definitely be a swelling and pain process after the operation. The swelling does not reach a peak just after the tooth is extracted, but has a process of development. The swelling and pain will reach a relative peak in about 2 to 3 days after the extraction and will be gradually relieved afterwards, and the swelling and pain will be relieved in about a week.
