Sore throat after tooth extraction is also a common postoperative condition, which is usually seen in the extraction of the posterior jaw teeth, most commonly the wisdom teeth of the lower jaw that are buried and obstructed. Since wisdom teeth are located in the last part of the tooth row, and the extraction of wisdom teeth is relatively traumatic, the operation often involves the incision and flap of the gums, the removal of the alveolar bone, and the division of the teeth, for this case, the extraction is traumatic and takes a long time, and the chance of swelling and pain after the operation is much higher than that of normal teeth, and the swelling to the outside will cause swelling in the cheek, and to the inside is exactly the throat. It is normal to have a painful process in the throat for 2-3 days after the wisdom tooth extraction. However, clinically it is also necessary to note that if the pain in the throat is still severe and tends to increase gradually more than 3 days after the tooth extraction, it is necessary to visit the stomatology department again to check whether the pain in the throat is not a postoperative physiological pain, but an infection of the postoperative extraction wound, which causes pain in the throat.
