There are certain types of orthodontic problems that are caused by the lack of enough bone growth across the upper jaw. A narrow or high-arched palate may benefit from widening with a Rapid Palatal Expander.

The upper jaw is composed of two pieces joined in the center by a suture, which allows it to be painlessly separated and spread. Once this has occurred, the two halves knit back together and new bone is laid down to make the jaw wider. This is permanent orthopedic change. The change is rapid and it won't hurt.

Activation is done with the key provided. Turn the key as instructed and return to the office at the end of 2 weeks for a check-up. Once the activation is complete, the expander must remain in place for 6 months before it can be removed.

A space will open between the two front teeth. It is desirable because it means the expander is working properly. It is only temporary and will close before the end of treatment.

Your mouth may be tender for the first few days after receiving you palatal expander. This is normal and should begin to disappear within a week. If it persists longer, please call our office. Rinsing with warm salt water will help take away the tenderness. Pain relievers may be given every 4-6 hours as directed for the first few days.

Reading out loud will help you get used to your new appliance. Speech will return to normal within a week to ten days.

Do not play with the appliance with your fingers or tongue. This can cause breakage. If a band comes loose or a wire gets bent, please call our office.

If you "cannot find the hole" when it is time for activation, it means you are in between turns. You must now find the hole towards the back of the appliance and complete the entire revolution to find the hole again. Now you will be able to make the activation correctly.
