Maxillary Expansion

The appliance given to you will widen (expand) your upper jaw. The key that we gave you fits into the appliance. The key is put into the appliance and pushed backwards to turn the expansion screw. Push the key backward as far as it will go. Then remove the key in this position so that it can be put into the next hole for the next turn. If the key is pulled forward again, even a little, the next hole will not be accessible. Either you or your parent can turn the expansion screw with the key.

Please follow your suggested schedule. Too many turns may cause discomfort. Too few turns will not produce the desired results.

If you feel discomfort, pain or dizziness, stop turning the appliance and call the office.

A space will open between the upper front teeth as the appliance widens the arch. Do not be alarmed, this is an expected change. The space will disappear as the front teeth come back together after the desired expansion has occurred.

Please use your toothbrush to clean the teeth and the appliance. With good oral hygiene, you will be protected against cavities and gum disease.

If you have any questions about the appliance, please contact the office.
