The reality is cruel. Some people do have a complete tooth, but there is no doubt that there is a gap in her inner cheek. If you have a big face and a big mandibular angle, even if you pull out four teeth, you are just a girl with a big face with four fewer teeth than normal people.
However, orthodontic tooth extraction does have an impact on the face shape, which is described in detail below.
The mandible accounts for one-third of the whole face, and the mandible+gums+mandibular muscles basically determine your face. Among the three, orthodontics is nothing more than the most unnecessary gum adjustment. Buck teeth, opening and closing or covering the sky will all affect the aesthetic feeling of the five senses. For example, the protruding upper teeth will press on the lips, resulting in a visual sense of lip valgus. . For example, many legendary big chins (Zhao Benshan and Xue Cun) are actually not the fault of the chin at all, but the lower gums are outward, covering the upper gums and visually stretching the whole chin outward.
However, the above injuries are the five senses. In terms of face shape, if the front contour has little effect, it is that the contour of the lower half of the face is beautiful, which depends largely on the gums.
The best example of adjusting face shape through orthodontics is AB. Regardless of plastic surgery or not, from the same point of view, the one on the left is wearing braces during orthodontics (aggravating the lordosis effect), and the one on the right is after orthodontics. Obviously, after orthodontic treatment, the jaw is adducted, the lips are not pushed out by the teeth, and the face seems to be smaller visually.
