Wisdom tooth extractions can be somewhat painful, but because they are performed under anesthesia, patients generally feel less pain. If the patient has a deep wisdom tooth, he or she will feel more intense pain during the procedure. For patients who are under anesthesia, there are some patients who may feel discomfort during wisdom tooth extraction, probably because the periodontal membrane tears when the tooth is about to be dislocated from the socket, causing the patient to feel pain. However, since the pain is not very intense and can be tolerated by most patients, there is no need to be too nervous during the extraction process. After the wisdom tooth extraction procedure, the patient should first bite down on a cotton ball to achieve pressure to stop the bleeding. No food should be eaten for 2-3 hours after the procedure is completed, and no brushing of teeth should be allowed for 24 hours.
