Wisdom teeth are not completely grown out and are still in the flesh. If they repeatedly cause pericoronitis, they can be removed. Wisdom teeth can be extracted if they are not fully grown. In general, wisdom teeth are prone to blockage due to the location and time of growth of wisdom teeth. If the wisdom tooth is completely buried in the alveolar bone, the growth position is normal, and the occlusal relationship of other teeth is normal, it can be recommended to keep it. If the tooth is partially erupted or has damaged the roots of the adjacent teeth, the obstructed wisdom tooth is more likely to form pericoronitis, causing tooth pain and even infection of the adjacent tissues, which affects normal life and work, and it is recommended to be extracted. The tooth can be extracted under local anesthesia, and according to the image, the tooth can be extracted by splitting the crown or splitting the root in pieces. Usually, the extraction requires incision and suturing, and the stitches are removed in a week or so. After extraction, it is necessary to pay attention to oral hygiene, avoid strenuous exercise, and avoid eating spicy and stimulating food to avoid infection of the wound.
