When the upper arch is too narrow to properly accommodate all of the permanent teeth, our orthodontic may recommend a palatal expander to gently widen the upper jaw. Dr. Erik TinHan will demonstrate how to adjust the expander to keep pressure on the jaw so that it continues to widen during treatment. For more information, and to learn if you would benefit from receiving a palatal expander in Pearl City, Hawaii, call 808-485-2444 to speak with our team at TinHan Orthodontics.
