Palatal Expander

Using the palatal expander, you gently push on your upper teeth each time an adjustment is made. This makes your upper jaw bigger. Here is a video that will show you when and how to change your expander. Make sure the expansion is safe by wearing the appliance for a few months to make sure it isn’t going to fall off or fall off again.

HOW TO ADJUST A PALATAL EXPANDER

These instructions are also available in a printable   PDF document.

Step 1

Tip the patient’s head back in a well-lit location.

Step 2

Insert the key into the hole until it is securely fastened.

Step 3

The key should be pushed toward the rear of the mouth. You’ll see that the fender rotates and a new hole appears. When the key comes into contact with the expander’s rear, the rotation comes to a halt.

Step 4

Remove the key by pressing back and down toward the tongue. The next keyhole should now be visible.
