Orthodontics can change some mouth shapes. However, there are differences between correction and plastic surgery. After the correction is neat, a good occlusion is achieved, or after the tooth extraction reduces the number of teeth, that's it, and it is impossible to further change the mouth shape. Plastic surgery can continue to be adjusted according to the needs of guests.

Some face shapes (mouth shapes) that can be changed by braces;

(1), use braces to correct irregular teeth. Irregular teeth generally cause mouth protrusion, which will return to normal after correction.

(2) For buck teeth with more teeth than bones, reducing the number of teeth after tooth extraction and correcting adduction with braces will improve the protrusion of the mouth to some extent, but it may not fully meet the requirements of patients, because excessive tooth extraction cannot be carried out.

(3), anti-jaw: also known as Tiandou, generally it will appear that the chin is long and the upper teeth are concave. After the teeth are corrected with braces, the bite is normal, the upper lip is full, the mouth is raised, and the chin is correspondingly improved, which is not so prominent.

(4) There are other quite minor or negligible changes.

In short, psychological preparation should be made before orthodontic treatment. Orthodontic treatment can only be improved, but not perfect. Correcting teeth can only change the face shape (protruding mouth) in a limited way. Those with bone eruption, bone overgrowth and skeletal hypoplasia need orthognathic surgery.
