Yang Mi, who holds up half the sky, has a beautiful thin face and has become the envy of many girls. Recently, when Yang Mi appeared on the TV program "Pretty Woman", he revealed that his little face was not born, but it became smaller after pulling out his teeth. Can tooth extraction really face-lift? This aroused the interest of girls who love beauty. Liu Jianyang, director of the Oral Beauty Department of Changzhou Shuguang Medical Beauty Hospital, said: From a medical point of view, tooth extraction and face-lifting are not scientifically justified! Tooth extraction can't change the bone width, pancake face, Chinese character face ... ugly face makes many girls who love beauty unhappy. How can they have beautiful and tight faces? It's too painful to grind your cheeks and cut your bones. Pulling out a tooth can achieve the effect of face-lifting, which is really exciting. Does tooth extraction really make your face smaller? Director Liu disagreed. "From a medical point of view, there is no scientific reason for tooth extraction and face-lifting!" He further explained that some people are overweight, so there will be more fat on their cheeks, or some people have more developed occlusal muscles, which will make their faces look wider, but people's faces are mainly determined by their bones. To put it bluntly, it is mainly because teeth grow on bones. Director Liu said: "For a simple example, when people get old, all their teeth will fall out, and the alveolar bone may shrink. The face looks flat, especially the cheeks. Visually, the face becomes thinner, but even when young, the alveolar bone will not shrink. In other words, when people are young, tooth extraction can't change the bone width. It doesn't matter if your wisdom teeth are pulled out and your face is thin. In response to Yang Mi's statement that "little face is not born, but becomes smaller after tooth extraction", some people say that Yang Mi may have pulled out his wisdom teeth. Wisdom teeth are located in the innermost position of oral teeth, which visually seems to really determine the face shape. In this regard, Director Liu said that the average person has four wisdom teeth, up and down or so, but some people are not long and the number of wisdom teeth is inconsistent. " According to statistics, 62% of people in China have wisdom teeth that are not straight, that is, they are inclined. Such wisdom teeth can lead to inflammation, damage to adjacent teeth and other problems, and need to be removed. But like the previous point of view, wisdom tooth extraction will not have the effect of face-lifting. "Director Liu said that even if someone really feels that his face is getting smaller because he has pulled out his wisdom teeth, it can only be said that it is a personal experience and feeling, which is not established in medicine and should not be promoted. Moreover, wisdom tooth extraction is a complicated operation, which requires qualified doctors in specialized hospitals to decide according to the condition. There are certain risks, such as damaging clinical teeth. Some people even need general anesthesia or hospitalization to extract wisdom teeth, and some wisdom teeth still have the value of preservation. Generally speaking, the extraction of wisdom teeth needs to be carried out by a specialist according to the condition, not that it can be pulled out. There will be wrinkles on your lips when you pull out tiger teeth. Many girls have tiger teeth, which outsiders will find very cute. But for women who love beauty, tiger teeth affect their image and make their faces and mouths bigger. They always want to pull out tiger teeth to make themselves more beautiful. Director Liu said that the scientific name of tiger tooth is tusk, which is located at the position of the third tooth on the alveolar bone. This tooth grows easily, because people grow teeth not according to the position of the first tooth, the position of the second tooth, the position of the third tooth and so on. Instead, it grows the first tooth, then the second tooth, then the fourth tooth, and then the third tooth, that is, it is easy. Director Liu said that doctors usually pull out the fourth tooth in order to help tiger teeth find a suitable position. There is only one tiger tooth, and pulling it out will affect the appearance of the face. The facial muscles attached to the root of tiger teeth are very important. Once removed, wrinkles will appear on the lips. Moreover, tiger teeth are sharp and can tear food, which is not recommended. Director Liu reminds everyone that teeth are our important partners. Normal arrangement of teeth has the function of chewing food and assisting pronunciation. Unreasonable tooth extraction can lead to air leakage and nerve damage. Tooth extraction is a surgical operation, involving many things. I suggest that there are many ways to pursue beauty, and don't do anything to your teeth for beauty's sake.
