Palatal Expander

The palatal expander widens the upper jaw by putting consistent gentle pressure on the upper molars with each adjustment. Please follow the instructions below to adjust your expander. You will wear your appliance until the desired expansion is achieved, generally several months, so that regression does not occur if appliance is removed.
