Wisdom tooth pericoronitis is a condition in which the wisdom tooth is blocked due to insufficient eruption position, and a blind pocket is formed between the crown portion of the tooth and the gums, causing inflammation when food bacteria become embedded. During the evolution of the human jawbone, as the food becomes finer and the jawbone is less stimulated, the space in the jawbone cannot accommodate the growth of wisdom teeth, and wisdom teeth are often blocked in the jawbone. Therefore, during the eruption process of wisdom teeth, the crowns of the wisdom teeth are partially or completely covered by the upper gingiva, and the food and bacteria embedded in the blind pockets enter into the fermentation and stimulation triggering inflammation. At the same time, because the upper and lower occlusal gums are often damaged by chewing food, the formation of ulcers, when the body’s resistance to decline in bacterial virulence enhanced, can cause wisdom teeth pericoronitis attack.
