Palatal Expander

The Palatal Expander is typically used during early interceptive orthodontic treatment, but it can also be used in conjunction with comprehensive orthodontic treatment. Attached to the upper molars by cemented bands, the Palatal Expander is an orthodontic device used to create a wider space in the upper jaw.

It is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.

When patients are still growing, their bone and connective tissue between the left and right halves of their upper jaw are very responsive to expansion. By simply activating the expander through turning a screw in the center of the palatal expander with a special key we provide, gradual outward pressure is placed on the left and right halves of the upper jaw.

This pressure causes an increased amount of bone to grow between the right and left halves of the jaw, ultimately resulting in an increased width.

When you brush your teeth, it is important to remember to use a Proxabrush (which we provide in the office) in addition to your regular toothbrush. Brush as usual and use warm water to flush under the expander.
