If the wisdom tooth is in normal position and can erupt completely, the blind pocket can be eliminated by itself. If the wisdom tooth is in abnormal position or cannot erupt completely, the blind pocket cannot be eliminated by itself, and the gingival flap around the crown needs to be removed, as follows. 1. Wisdom teeth in normal position and can fully erupt: the gingival flap formed by the blind pocket can be gradually eliminated with the eruption of wisdom teeth, without special treatment. 2. Wisdom tooth position is abnormal, or can’t erupt normally: the blind pocket formed by the gingival flap usually can’t be eliminated by itself, and it is necessary to carry out pericoronary gingival flap excision under local anesthesia to prevent recurrence of pericoronitis of the wisdom tooth, and it can be extracted if there is no retention value of the wisdom tooth. It is recommended to go to a regular medical institution to receive professional treatment with the help of a doctor.
