Palatal expander model demonstrating orthodontic device used to widen the upper jaw during treatment at Jacklyn Kurth Orthodontics.The palatal expander “expands” (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. The animation below will instruct you about when and how to adjust your expander. When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent regression.
