If you get dry socket after wisdom tooth extraction, you should immediately visit the hospital for systematic treatment. First of all, the extraction wound should be scratched under local anesthesia to scrape away the infected material and inflammation in the extraction wound. Then the extraction wound should be irrigated, alternating between hydrogen peroxide and saline, until there is no more putrid smell in the extraction wound and a fresh and clean bone surface is revealed. Finally, the extraction wound should be filled with iodoform oil gauze or iodoform sponge to promote the growth of granulation tissue and to provide anti-inflammatory drugs to relieve pain. In general, the oil gauze is extracted from the extraction wound in 5-7 days, by which time the wound is basically healed.
