Rapid Palatal Expander (RPE)

How does it work?

Turning the miniature screw applies pressure through the teeth to expand the jaw bone. The screw is in the center of the palate.

How long will the expander be needed?

Upper expansion is generally completed within 3 months while lower expansion requires approximately 6 months. Expansion must be retained, often with the same expansion appliance, for a minimum of 6 months post expansion. Most expanders are left in place 9-12 months.

How does it feel?

You may experience excess saliva until your mouth adjusts to your appliance. You will feel pressure on the teeth or roof of the mouth after turning the screw. The pressure lasts 1-5 minutes. There should be no discomfort after the first week. Ibuprofen may be beneficial during this initial phase. During this phase of treatment, will be monitoring your child’s treatment very closely. Therefore, we recommend you DO NOT SKIP APPOINTMENTS!

Tips!

• Count every turn. Never turn more than the recommended turns.
• Always turn in the direction of the arrow until the next hole appears, then remove the turning lever.
• If the expander is loose, stop turning this screw. Call for an appointment so we can re-cement it back in.
• A space may open between the front teeth. This space will reduce on its' own once the turns are stopped.
• If the screw resists turning, offers no resistance, or pulls apart, stop the turns and call our office for an adjustment.
• Be sure to brush around the appliance very thoroughly, check for plaque and use fluoride toothpaste daily.
• Speech will be slurred and swallowing difficult at first until the tongue adjusts to the appliance. Practice reading out loud.
