It is very likely to suffer from dry socket on the tenth day of tooth extraction. There will be some initial symptoms of dry socket around 3-4 days, manifested as no significant improvement in the extraction wound, no relief of pain, and gradually increasing pain, which may become more and more intense in about a week. At this time, if no treatment is carried out, there will be a putrid odor in the mouth, and by about the tenth day if the patient still does not receive treatment, it will aggravate the severe pain. The reason why dry socket is developed is because the clot has been dislodged and the extraction socket is not protected.
