When conducted by a professional orthodontist, orthodontic treatment itself is not harmful to your teeth. Patient behaviors during treatment, however, can cause harm or damage. Poor dental hygiene—like not brushing or flossing regularly—a diet heavy in sugary, chewy, or crunchy foods or beverages that can damage the orthodontic appliance, and avoiding dental cleanings or orthodontic treatment appointments and adjustments can cause long-term damage to your teeth. Your unique orthodontic treatment has been carefully designed to guide your jaw into its proper alignment; without proper care or timely and necessary adjustments, your mouth and teeth are at risk for developing cavities and will not function the way they should. To further ensure your orthodontic treatment does not harm your teeth, be sure to choose an orthodontist who has been certified by the American Board of Orthodontics and/or is a member of the American Association of Orthodontists (AAO). Certified orthodontists have extensive experience in planning, administering, and monitoring orthodontic treatments, including the safe application and removal of devices as well as the physiological movements needed for proper alignment.
