What Is a Palatal Expander?

A palatal expander is a custom-fitted orthodontic appliance used to widen the upper jaw (also known as the maxilla). It’s commonly used in growing children whose jaws are still developing and is often part of a two-phase orthodontic treatment plan. By addressing jaw size and structure early, we can make room for adult teeth and create better overall alignment.

How Does a Palatal Expander Work?

The expander fits snugly on the upper molars and uses a small central screw that is gently turned at home, usually once or twice a day. This activates a gradual widening of the upper jaw by applying light, consistent pressure to the palatal bones. Since children’s bones are still flexible, this process is safe, effective, and typically painless, with most kids adapting quickly.

The expansion process usually takes a few weeks, but the appliance remains in place for several months to allow the new bone to stabilize and set.
