The bone spur found after tooth extraction may be due to the sharp and acute edges of the extraction sockets after the patient’s tooth extraction. The physician did not notice and did not remove the sharp edges of the extraction sockets in time, which led to the patient’s self-conscious growth of bone spurs and caused the patient pain and other discomfort. Patients are advised to go to the oral and maxillofacial surgery department promptly if they notice any discomfort after tooth extraction or if the edges of the extraction sockets are sharp and sharper when licked by the tongue. The physician can perform an incision and flap under local anesthesia to remove the sharp edges, and the bone spur can be removed. The precautions for the patient after removal of the bone spur are approximately the same as those after tooth extraction, two hours before eating and drinking, and do not brush or rinse your teeth on the same day. Stitches may be placed after cutting the gums. Patients are advised to remove the stitches and follow up in a week, and they will be cured if they do not have any symptoms.
