The correct term for an end tooth is a third molar, also known as a wisdom tooth. Third molar pain is usually caused by pericoronitis, pulpitis, apical periodontitis, and the methods to relieve pain quickly are rinsing and anti-inflammatory, opening and draining the pulp, incision and drainage, and extracting the tooth, etc., as follows. 1. Rinsing and anti-inflammatory: For third molar pain caused by pericoronitis, you can use saline to rinse the blind pocket until the overflow liquid is clear, and then apply iodized glycerin into the gingival pocket, which can be anti-inflammatory and analgesic. 2. Pulp opening and drainage: For third molar pain caused by acute pulpitis, the pain can be relieved by opening and draining the pulp to relieve the high pressure in the pulp cavity, but wisdom teeth with no retention value can be extracted directly. 3. Incision and drainage: For third molar pain caused by acute periapical periodontitis, the abscess can be incised to drain the pus and relieve the pain. 4. Extraction: Wisdom teeth are generally not very useful, when the growth is not in the right position, there is no opposing teeth, you can consider direct removal of wisdom teeth, but wisdom teeth pericoronitis need to wait for the inflammation to be controlled before extraction. There may be other reasons for third molar pain, so it is recommended to go to the hospital in time.
