Palatal Expander

palatal expander modelA palatal expander "expands" (or widens) the upper jaw by putting gentle pressure on the teeth each time the expander is activated. See below to learn how to activate your child's expander. Once the desired amount of expansion is achieved, the expander will remain in the mouth for several months afterwards to allow the bone to settle and to prevent relapse.  Be sure to check with Dr. DeCamps on your activation schedule.
