Teeth protrusion can not be improved on its own, you need to go to the hospital according to the cause of protrusion, targeted orthodontic or orthognathic treatment. 1. Orthodontic treatment. If the protrusion of teeth is caused by malocclusion, orthodontic treatment is needed to improve it, which can be done by expanding the dental arch, extracting the teeth or aligning the teeth with the orthodontic appliances, retracting the front teeth, and arranging the teeth neatly in the dental arch. 2. Orthognathic treatment. If the protrusion of teeth is caused by overgrowth or deformity of the jawbone and cannot be improved by orthodontics, orthognathic surgery is needed to trim the protruding jawbone in order to retract the front teeth. When teeth protrusion occurs, it is recommended to go to the hospital for examination and treatment in a timely manner to avoid aggravating the change of face shape and affecting the aesthetics.
