Hello, under normal circumstances, the orthodontic cycle is generally 2 years. It has been six years since you corrected it. You haven't corrected it. It's not normal. It is recommended to go to the orthodontics department for examination. Bad dentition can be divided into dentition and bone dentition. Orthodontics generally takes 2 years, so it is recommended to choose a doctor with rich experience in orthodontics. In addition, the bone needs corrective surgery.
