Currently, there are many beauty-conscious girls who try to achieve a slimmer face by removing their wisdom teeth, not realizing that the removal of wisdom teeth does not have a slimming effect on the face. The shape of the human face is mainly supported by the upper and lower jaws, especially the shape of the mandibular angle part of the lower jaw, which directly affects the shape of the lower 1/3 of our face. To put it simply, the average jaw angle of an average person is about 120 degrees. The smaller the jaw angle is, the closer it is to a right angle, and the closer the face is to a “Chinese character face”; with a larger jaw angle, the more slender the face appears to be. Nowadays, a lot of so-called “face slimming surgery” is actually grinding the lower edge of the lower jaw angle to nearly 120 degrees. Wisdom teeth are erupted after the jawbone is fully formed, so the removal of wisdom teeth will not change the angle of the jaw, and it is not possible to achieve the effect of face slimming. Chen Guokun, Department of Oral and Maxillofacial Surgery, Stomatological Hospital of Shandong University Some people feel that their faces have become thinner after wisdom teeth removal, probably because the swelling and pain after extraction leads to a reduction in eating, when the swelling of the face subsides and after the diet control during the recovery period, it will give people the illusion that wisdom teeth removal is a slimming of the face. In reality, wisdom teeth are a biological trait that was abandoned during human evolution. Due to individual genetic differences, each person varies in the outward expression of this trait. In most people, the tooth germ of the wisdom teeth develops after tooth replacement, and in only a small percentage of people do the wisdom teeth erupt successfully and naturally. For those wisdom teeth that can erupt successfully, establish a good occlusal relationship and perform their functions, and are free of caries, periodontal lesions, and risk of infection, and do not interfere with other teeth, they can be retained completely. Wisdom teeth that do not erupt naturally in an orthodontically correct position and often cause peri-coronal inflammation or impact on neighboring teeth are recommended to be extracted as soon as possible. It should be noted that wisdom teeth extraction, like any tooth extraction, is an oral-alveolar surgical procedure with certain indications, contraindications and surgical risks. Patients with severe cardiovascular disease and high blood pressure above 180/100 mmHg, hyperthyroidism, diabetes, liver or kidney disease and acute infectious diseases, or women who are menstruating, pregnant or breastfeeding are not suitable for extraction. In addition, if the patient has any discomfort in the mouth, he/she must go to a regular hospital and choose to receive the appropriate treatment under the professional guidance of the doctor.
