Wisdom tooth pain may be caused by pericoronitis, caries, endodontitis, periapical periodontitis, etc. It can be relieved by pericoronitis rinsing, filling, pulpotomy, root canal treatment and extraction. 1. Peri-coronary flushing: Wisdom tooth pain may be caused by peri-coronary inflammation, mainly due to the position of the wisdom teeth backward, cleaning difficulty, resulting in food debris embedded in the gums of the blind pocket formation of inflammation, resulting in the wisdom teeth, peri-coronary gingival redness, swelling, pain, pus overflow and other phenomena, you can go to the hospital to use hydrogen peroxide and saline alternately rinse, and on the composite iodized glycerine to carry out the anti-inflammatory. If wisdom teeth repeatedly cause pericoronitis and other indications for extraction, wisdom teeth can be excluded. 2. Fillings: If the wisdom tooth is decayed to the extent that deep caries causes pain, and there is a good occlusal relationship with the opposite jaw teeth, the decayed tooth tissue can be cleaned up and then fillings can be made to alleviate the pain. 3. Pulp Drainage: Wisdom tooth decay reaches the pulp cavity and causes pulpitis, etc. By removing the decayed material and uncovering the top of the pulp chamber to achieve drainage, it can improve the congestion of the pulp and thus relieve pain. 4. Root canal therapy: When wisdom teeth have periapical inflammation that causes pain, root canal therapy can be performed on the wisdom teeth to relieve the pain caused by inflammation of the periapical tissues. 5. Extraction: In case of acute pulpitis or residual root causing pain, wisdom teeth can be extracted after taking panoramic radiographs to relieve the pain completely.
