Mouth curvature caused by convex teeth can be improved by orthodontic treatment, and orthognathic surgery should be carried out if there is a bony problem at the same time. 1. If the teeth are bulging and causing the mouth to turn up, the teeth can be straightened by wearing metal braces or invisible braces. If there is overcrowding of the teeth, some of the teeth need to be extracted to provide space before orthodontic treatment. 2. If there is convexity of the teeth and bony anterior convexity at the same time, the effect of simple orthodontic treatment is poor, and it is necessary to carry out surgical treatment at the same time, such as orthognathic surgery, etc., which can improve the phenomenon of mouth cocking. If you have convex teeth and a protruding mouth, go to the appropriate hospital in time and choose the appropriate treatment to improve the situation as soon as possible.
