Orthodontics does change the face shape, but the change varies from person to person and from patient's age. For example, in the process of children's growth and development, the appliance can change the occlusal relationship of teeth, the development trend of dental arch and jaw, and can make use of children's productive potential to change and improve children's face shape.

But for adults, braces can also change the face shape to some extent. For example, some patients put on braces, so that the teeth that were originally protruding outward are retracted, and the oral cavity is retracted with the retracted teeth, so that the outline of the mandible is more obvious than before, thus improving the appearance of the convex surface, but this face change is mainly reflected in the front and back direction of the side.

Other patients have a tight bite and a short ratio of 1/3. By lengthening the teeth and rotating the mandible, the ratio of 1/3 under the face can also be changed to some extent, making the facial ratio more harmonious. Therefore, we can change the adult's face to a certain extent, but we should realize that orthodontics has limited changes to the adult's face. For example, it is impossible to change a Chinese character face into an inverted triangle face only through orthodontics.

Extended data

1, pain and discomfort for the first time.

Discomfort may occur three days before wearing the appliance, and the tissues around the teeth will be activated under the guidance of strength, so some patients will have tooth weakness and no strength to chew food. It usually takes about a week to get used to the intensity of eating and restore normal chewing function, so they must be patient.

2. Treatment of ulcer

Because the oral mucosa is repeatedly rubbed by instruments, oral ulcers may occur. At this time, you can choose drugs for ulcers, or use special mucosa for protection, which can effectively relieve pain. Generally about a week, the ulcer can heal itself. If the sharp part of the steel wire irritates the mucosa, contact the doctor in time.

3. Do a good job in diet care

In fact, the appliance can be removed, but it will lose its corrective function. Avoid eating foods that are too hard and too big, such as nuts and ribs. When eating fruit, you can cut it into small pieces before eating. If you are subjected to excessive force, it will hit the appliance and cause it to loosen.
