Many times in orthodontics, doctors will improve the arrangement of teeth, add appropriate designs according to the different conditions of each patient from an aesthetic point of view, adjust the positions of teeth, lips and jaws of patients, and naturally change the face shape, so as to achieve the effect of changing the face shape to a certain extent.

In most orthodontic cases, the moving direction of teeth is the front-back direction, so the appearance of facial side changes the most. For example, in patients with buck teeth, because the front teeth move backwards through the teeth, the lips will become easier to close, so the face shape will be more harmonious and beautiful from both the side and the front. Because it involves the problem of future stability, the width of dental arch does not change much during general orthodontics. Even in some adolescent cases, rapid maxillary expansion may be used to correct maxillary arch stenosis, but it will not have much impact on facial width. Resources come from: www.361kq.com.

In fact, after orthodontics, the face of teenagers will change more than that of adults, but the main reason is the influence of growth and development. Even if a teenager does not receive orthodontics, his face will change because of the growth and development of bones and soft tissues. However, during this period, functional appliances or extraoral instruments can be used in orthodontics to change the direction and degree of jaw growth, so as to change the face shape and make it more beautiful.
