You can take pain medication for tooth extraction, but patients need to distinguish whether the pain is physiological or pathological. In general, when extracting more traumatic teeth, for example, buried and obstructed wisdom teeth, the operation involves the incision and flap of the gums, involving debridement and division of the teeth, there will be physiological pain after the operation, and this pain may be more intense. In this case, you can take pain medication as appropriate, commonly used as the first step of pain relief and analgesic drugs, such as ibuprofen, acetaminophen, aspirin, celecoxib and so on. If it is not this kind of pain, it is the sudden appearance of extraction trauma pain more than 3 days after the extraction. At this time, we must pay attention to check whether there is redness, swelling and pus spillage in the extraction wound and whether there is any odor in the mouth, because it is possible that the pain is not just postoperative, but there is a pathological postoperative infection, and taking pain medication cannot cure the infection, so we must go to a professional dentistry department to check again.
