If the protruding mouth is caused by teeth, it can be improved by orthodontic treatment, and if it is caused by bony problems, it can be treated with orthodontic and orthognathic treatment.
The protruding mouth can be caused by dental problems, the teeth grow outward which can cause the lips to protrude outward, at this time, orthodontic treatment can be carried out to retract the teeth inward, which can improve the effect of protruding mouth.
In addition, protruding lips can also be caused by bony problems that cannot be restored by straightening the teeth alone. In this case, combined orthodontic and orthognathic treatment can be performed to adjust the bony relationship to improve the protruding mouth.
Both orthodontics and orthognathic surgery have certain risks, so you need to go to a regular hospital for an interview, and the doctor will decide on the appropriate treatment after a comprehensive judgment.
