A 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.

In a well-lit area, tip the patient's head back.
Place the key in the hole until it is firmly in place.
Push the key toward the back of the mouth. You will notice the fender will rotate and the new hole will appear. The rotation stops when the key meets the back of the expander.
Press back and down toward the tongue to remove the key. The next hole for insertion of the key should now be visible.
