The hazards of wisdom teeth] Zhuo Shaoyang, Department of Oral and Maxillofacial Surgery, Shandong University Stomatological Hospital, Shandong, China I. Recurrent episodes of pericoronitis A blind pocket is formed between the soft tissue around the crown of the blocked wisdom tooth and the tooth, causing the accumulation of food and bacteria, and when resistance decreases, pericoronitis is inevitable. The general anti-inflammatory treatment can treat the symptoms but not the root cause, so pericoronitis will recur. Secondly, caries is easy to accumulate food residue between the wisdom tooth and the second molar in the wrong position, and it is not easy to clean, so it can form caries in several months and directly destroy the tooth tissue. (Thank you very much for the picture provided by Professor @ Microdentist! ) Third, jaw pain, grinding teeth obstructed wisdom teeth often can not establish a normal occlusal relationship with the teeth of the opposite jaw, which can lead to the temporomandibular joint popping, open mouth pain, night grinding teeth and other symptoms for a long time, which has a greater impact on the physical and mental health of young adults. There is evidence that some obstructed wisdom teeth are the foci of some trigeminal neuralgia. The jawbone that holds the teeth continues to degenerate and become smaller, so wisdom teeth obstruction is the inevitable result. Tip: Removal of blocked wisdom teeth does not have any adverse effect on the functions of chewing and speech, plus it is the most effective way to treat blockage, therefore, it is recommended to remove the blocked wisdom teeth that cause the above-mentioned harm as early and decisively as possible.
