Improvement of lip protrusion needs to be selected according to the degree of protrusion, dental protrusion can be treated with orthodontic treatment, and bony protrusion needs to be treated with combined orthodontic and orthomandibular treatment. 1. Orthodontic treatment: If the degree of protrusion of both jaws is mild and caused by protruding teeth, you can choose invisible braces or traditional steel braces for orthodontic treatment, and you should change the bad habit of open-mouth breathing in your daily life, which can improve the problem of protruding lips. 2. Orthodontic orthognathic joint treatment: due to genetic or developmental factors, the upper and lower jaws develop abnormally and protrude forward compared with normal people. When it is difficult to achieve good results with orthodontic treatment alone, you can consider orthodontic orthognathic treatment, which is a combination of surgical movement of the jaws and orthodontics. If you need to improve the protruding lips, it is recommended that you visit a regular hospital and have your lips treated by a professional doctor.
