Many patients are very worried about whether they have dry socket after wisdom tooth extraction, and they feel like talking about it. First of all, what is dry socket? At present, dry socket is considered to be a limited osteitis that occurs locally in the extraction socket after wisdom tooth extraction. Normal extraction socket healing is the result of a high quality filling formed after the tooth extraction procedure when the blood clot fills the extraction socket, which coagulates and protects the socket and promotes wound healing. During the healing process, however, if the clot is shed quickly or becomes infected, it may lead to dry socket syndrome. What are the signs of dry socket? The typical manifestation is a severe pain involving the extraction socket and the ipsilateral ear and temple that occurs 3 or 4 days after the extraction, and the effect of oral pain medication is not obvious, or the existing pain is significantly aggravated. Therefore, if you have the above symptoms two days before the extraction of wisdom teeth, you do not have to be too nervous and can try pain medication because the diagnosis is not clear at this time and blind treatment may interfere with the normal healing of the wound instead. The second is the extent of pain involvement, especially in the ear and temple. If it is limited to the extraction socket, there is a higher possibility of postoperative reaction. The third is the ineffectiveness of general painkillers, for example, if the pain is not effective at all with drugs like Fenbendazole, you may have to come to the hospital for examination. Is dry socket that bad? The occurrence of dry socket does increase the pain of the patient, but there is no need to be overly nervous. As long as the extraction sockets are rinsed and wiped with hydrogen peroxide and saline under local anesthesia, and medication to stop the bleeding and pain is put on, most patients will have significant relief within a day or two after treatment, and the medication can be removed in about a week.
