If your child has a narrow upper jaw, crowding, or bite misalignment, an orthodontic palatal expander may be the solution. At Gellerman Orthodontics in Huntington, NY, we specialize in early interceptive treatments — like palatal expansion — to help guide proper jaw development and create the space needed for a healthy, functional smile.
A palatal expander gently and gradually widens the upper jaw to create the space your child needs for a healthy, aligned smile. Early expansion can help avoid the need for tooth extractions, guide permanent teeth into better positions, and correct crossbites. It also improves facial symmetry and, most importantly, can open the nasal airway, making it easier for your child to breathe through their nose.
By using this appliance during your child’s growth phase, we’re setting the foundation for better oral health, improved breathing, and long-term bite stability.
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.
Benefits of Incorporating a Palatal Expander into Orthodontic Treatment
Using a palatal expander as part of early orthodontic care offers multiple long-term benefits:
- Creates space for permanent teeth to erupt naturally
- Prevents crowding and reduces the need for extractions
- Improves bite alignment, correcting crossbites and narrow arches
- Enhances facial symmetry for balanced growth
- Opens the airway, supporting healthy nasal breathing and reducing the risk of sleep-disordered breathing
Early intervention with a palatal expander can make future orthodontic treatment shorter and less complicated, helping your child achieve a confident, healthy smile that lasts a lifetime.
