Why does wisdom tooth extraction hurt?

There is a normal physiological pain process after wisdom tooth extraction, just as there is a pain process after a bump or cut, and the pain will gradually ease. In general, there is no pain during wisdom tooth extraction because of the presence of anesthetics, and the pain gradually starts about an hour after the extraction because the effect of anesthetics wears off, and most patients can tolerate the pain at this time. If the pain is not tolerated, you can consider applying more basic analgesic drugs, such as fenbendazole and ibuprofen. If the pain is more than 3-4 days old and there are signs of persistent aggravation, it is recommended to visit a specialized dentist again to rule out whether the pain is caused by infection after the extraction.
