It is possible to take pain medication if you have just had a tooth extraction that hurts a lot. Generally, for some more traumatic extractions, such as the extraction of ambiguous obstructive teeth, it is normal to have more severe pain after the operation because the extraction process often involves flap and bone removal, which is more traumatic and takes longer. You can take some analgesic medications for the symptoms, generally common are aspirin, ibuprofen, acetaminophen and so on. This kind of pain relief and analgesic drugs of the 1st stage have relatively good analgesic effect with less side effects, and can be used for post-operative pain. However, patients should also note that if the pain in the wound area is still more intense and significantly aggravated after more than 3 days of tooth extraction, then it is necessary to go to a professional dentistry department for a second look to rule out post-extraction infection. Because the post-extraction infection cannot be treated by the application of analgesic drugs alone, it must be combined with the application of anti-inflammatory drugs and, if necessary, secondary treatment for the extraction wound.
