Palatal Expander
A dental device that widens the upper jaw to create space for properly aligned teeth and improved bite function.
An orthodontic appliance fixed to the upper molars that applies gentle outward pressure on the palate over several months to gradually widen the upper jaw and create space for properly aligned teeth.
The expander is bonded to the upper molars, and a key is used to turn a central screw a small amount each day, gradually applying outward pressure that slowly widens the palate over several months.
Creates the space needed for proper tooth alignment while the jaw is still developing, often reducing the need for extractions or more extensive orthodontic work later.
