Orthodontics not only corrects teeth, but also corrects soft tissues of mandible and face. Want to improve, basically choose orthodontics or orthognathic surgery. For example, if a person's teeth are aligned but he thinks his face wants to be smaller, then his face will be smaller if his teeth are pulled out and he is orthodontically treated. Of course, you are only 15 years old, and you will grow and develop, and there will be changes in the future.
