How do palatal expanders work?
Working with your child’s natural growth and development, palatal expanders use gentle pressure to widen the upper jaw in a pain-free way. These custom-made appliances fit comfortably over several upper teeth in the back of the mouth. Every day, parents gradually turn the expander with a specialized key. This activates the appliance and applies pressure that gradually expands the jaw.
Once the jaw has expanded to the ideal size, patients continue to wear these devices for a few months while new bone forms. This bone stabilizes the newly expanded jaw for permanent results.
