Excellent brushing is the most important thing to keep the expansion appliance clean and in good working order. The main area to concentrate on when brushing is the margin of gum tissue above the bands.

There are certain foods which are not suitable for eating while wearing an expansion appliance. Chewy foods like toffee and bubble gum can get caught in the expansion device and pull the bands out of place. Also crunchy foods like ice and nuts can damage the appliance.
