A protruding mouth can be improved with braces. A protruding mouth is usually characterized by a protrusion of the upper and lower teeth, or the upper and lower jaws, resulting in a raised lip. A protruding mouth can be improved by wearing orthodontic appliances, also known as braces. However, the effect of wearing braces to improve the protruding mouth varies from person to person. If the protruding mouth is caused by uneven alignment of teeth, wearing braces can shrink the teeth back, which can effectively improve the protruding mouth problem. If the protruding mouth is caused by abnormal jaw development, it is generally difficult to achieve good results simply by wearing braces, and generally need to be combined with orthodontic treatment. Orthodontics can restore the patient’s normal tooth alignment, followed by orthognathic surgery, which can effectively improve the protruding mouth. If you have a protruding mouth, you should go to the hospital in time and choose a suitable treatment plan under the doctor’s guidance.
