What is a Palatal Expander?
Attaching to the roof of the mouth (also known as the palate) the palatal expander is an orthodontic appliance that “expands” (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. By widening the roof of the mouth, the palatal expander makes room for crowded teeth. After the expansion has occurred it is required that patients continue to wear their palatal expander for several months to solidify the expansion and prevent regression.
Below we highlight all the steps necessary for adjusting the palatal expander.
How to adjust a palate expander
Adjusting your palatal expander is a simple process that can be done in four easy steps.
Step 1: Locate the Palatal Expander
In a well-lit area, tip the patient’s head back to reveal the palatal expander on the roof of their mouth.
Step 2: Place the Key Into the Expander
Place the key in the hole of the palatal expander until it is firmly in place.
Step 3: Turn the Key in the Palatal Expander
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.
Step 4: Remove the Key
Press back and down toward the tongue to remove the key. The next hole for insertion of the key should now be visible.
