Palatal Expander Instructions

palatal expander modelThe palatal expander “expands” (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. Dr. Gellerman 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.

What To Expect:

  • A temporary lisp and/ or change in speech
  • Excess saliva for a few days
  • Difficulties swallowing at first
  • You may develop a slight headache
  • Some pressure in the back molars, on the roof of the mouth, and nose area might be felt during activation
  • Space opening between front teeth is the indication that the expantion is working. Your teeth will shift later to fill the gap.
  • The bite may feel off

How To Care For Your Expander:

  • Rinse/ swish with water or Waterpik to flush out food between the expander and the roof of your mouth
  • Brush with a toothbrush around the entire expander (including all metal parts and screw)
  • Maintain soft diet for the first few days
  • Avoid any sticky and hard foods that can dislodge the expander
