Palatal Expanders
A palatal expander is a fitted appliance used to gradually widen a narrow upper jaw. As the expander is adjusted over time, it creates additional room for crowded teeth and can help correct a crossbite, guiding the upper and lower arches toward a better fit.
What Palatal Expanders Address
- Crowding — widening the upper arch can create space so teeth have room to align properly.
- Crossbite — expansion helps correct situations where the upper teeth sit inside the lower teeth when biting down.
- Narrow Upper Jaw — gradual widening addresses a palate that is too narrow to support the developing teeth.
How Treatment Comes Together
Dr. Aesha Chaudhry, an orthodontist and board-certified pediatric dentist, evaluates the jaw and bite to determine whether a palatal expander is an appropriate part of treatment. Planning may draw on other tools available on site.
- Digital Dental X-Rays — provide a detailed view of developing teeth, roots, and jaw structure.
- Digital Intraoral Scanning — captures a precise 3D model of the teeth without messy impression trays.
- Digital Treatment Planning — combines scans and X-rays into one plan so each stage of movement is mapped in advance.
Palatal expanders are often used alongside braces or other orthodontic appliances as part of a broader plan for straightening teeth and improving how the bite fits together.
