A palatal expander is a device used to widen the upper jaw so that the upper and lower teeth will fit together better. It is often used to create room in the mouth prior to braces. A space may, but will not always, open between the upper two front teeth during the first few weeks as the appliance widens the upper arch. The space will disappear in the following weeks once the turning has stopped and braces are placed.
Palatal Expander Instructions
- In a well-lit area, tilt the patient’s head back.
- Place the key in the hole until it is firmly in place.
- Push the key towards the back of the mouth. You will notice the fender will rotate and a new hole will appear. The rotation stops when the key meets the back of the expander.
- By pushing back and down (toward the tongue), remove the key. The next hole for the key should now be visible.
