Palatal expander

Palatal expander

Some orthodontic problems can be the result of a narrow jaw. At Dr. Paul J. Styrt, Specialists in Orthodontics & Pediatric Dentistry, we can plan treatment that widens your jaw prior to embarking on orthodontic treatment to straighten your teeth. To achieve this we use the palatal expander.


What is a palatal expander?

The palatal expander "expands" (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent regression.
