Convexity of the mouth can be improved by wearing braces, surgical correction and so on.
1. Wearing braces: Convexity of the mouth can be caused by buck teeth or misalignment of the teeth, which can be alleviated by wearing braces to correct the deformity of the teeth alignment, and you should pay attention to good oral care in normal times.
2. Surgical correction: Mouth protrusion can be caused by wide and extended maxilla, which requires jawbone resection or osteotomy to shorten the maxilla and recede inward to improve mouth protrusion.
When the mouth is protruding forward, consult a regular hospital, and make a reasonable treatment plan after the professional doctor evaluates the condition. It should be noted that the younger the age, the better the effect of the corrective surgery, and the lips should be avoided from opening the mouth too much or laughing within 1 week after the surgery.
