Quad Helix Expander

This appliance is used to expand the upper jaw. It attaches to the upper molar bands. It is also used to stop thumb and finger sucking.

Dr. Powell or Dr. Bre adjusts it at each appointment to continue the expansion.


Temporary soreness can be expected for 3-7 days after the initial appointment. Be sure to brush your tongue and rinse with salt water to help the tongue adapt to the Quad.

Speech can be difficult at first, but after a day or two, it will return to normal.

For the first few days some foods like pizza and peanut butter are difficult to eat. For the duration of treatment all sticky foods should be avoided.

You will notice an increase in saliva flow. This will slow down after a few days.

If the Quad should become loose or broken, please call our office so it can be fixed.

This appliance is usually in for 3-6 months.
