Some people change the problem of large cheeks by extracting teeth, hoping that the absorption of bone after extraction may improve the shape of the face. Pulling out wisdom teeth to improve the "big face" can be, but pulling out the function of the good teeth need to be careful, otherwise it will affect the future eating, but also speed up the aging.

　　In physiognomy, there is a saying that "if you see cheeks behind your ears, you will have no love for others", which means that the left and right side of the "cheekbones" (jaw angles) are very large and open horizontally. This kind of person is said to be "aggressive, confrontational with elders and superiors, and quarrelsome with peers and friends, easily turning against each other". For example, in the Romance of the Three Kingdoms, Zhuge Liang said, "Wei Yan has a rebel bone at the back of his head, and he will rebel in the future", meaning that the sharp angle of the cheekbone can be clearly seen from the back.

　　Cheek bone big "for the opposite" is no scientific basis of superstition, but long a cheeks big "big cake face" is obviously not beautiful, many young women are pursuing goose egg face and melon face. Therefore, people have moved to extract the teeth to rectify the face of the mind, because the teeth extraction will make the alveolar bone resorption, so that the cheeks become smaller. A dentist said that through the extraction of teeth to cosmetic surgery must be careful: if the wisdom teeth, may wish to remove wisdom teeth; if "to be beautiful, not to life," the extraction of functional teeth, not only affect the future of eating, but also may become more ugly.

　　The shape of one's face is related to one's living habits since childhood. For example, babies in the West sleep on their stomachs, which is more likely to produce a melon face. However, sleeping on one side all the time or sitting with one side of the face propped up may lead to asymmetry of the face. Stroking the chin, as suggested by the elderly, may also change the shape of the face when performed over a period of years. In addition to the cheekbones, a pretty face should also meet the basic requirements of the upper and lower golden ratio, left-right symmetry, as well as a number of aesthetic criteria, such as the chin protuberance (the tip of the chin), the lips and the tip of the nose determines whether the side of the head of the person is beautiful or not: if the three points into a line, or the upper and lower lips slightly inward a little bit, the better look.

　　The lower third of the face is determined by the lips, teeth and upper and lower jaws. In addition to the soft tissues such as lips and other factors, the number of teeth and the amount of bone is not coordinated to create a poor appearance, for example, if there are fewer teeth and more bone, the teeth will appear sparse; if there are more teeth and less bone, it will result in buck teeth, whistling teeth, and misalignment of the teeth. After a long period of human evolution, the amount of bone has gradually become relatively insufficient, making the wisdom teeth, the last teeth deep in the tooth row, redundant - they are easy to grow crooked because of the lack of space, and they are seldom used for chewing food, and they are easy to be decayed due to the lack of cleanliness because of the inaccessibility of the toothbrush when brushing.

　　Wisdom teeth also tend to pinch the walls of the cavity and the root of the tongue and cause infections, and in terms of their impact on appearance, they can also make a person's face longer. Therefore, if you have wisdom teeth in your face, you can safely remove them, as the cheekbone will shrink naturally. Next, you can consider extracting the bicuspids between the tiger teeth and the molars. They are small, thin and relatively limited in function, so if they are decayed, they can be safely extracted. Braces often take bicuspids, one at the top, one at the bottom, and one at the right.

　　The cheekbone doesn't shrink instantly after extraction - that can only be done by surgical cutting. According to Liu Bing, bone resorption and remodelling takes at least three to six months, and there will be some changes a year or two after the extraction. People before the age of 25 years old bones continue to rebuild, face shape is softer, suitable for tooth extraction cosmetic surgery; after 25 years old to do to be cautious, and more than 30 years old people's jawbone has been stereotyped, there will be little effect.
