A palatal expander is an orthodontic appliance that gradually widens the upper jaw to correct narrow palates, crossbites, and crowding. It works by applying gentle, steady pressure across the midpalatal suture, the natural growth seam in the roof of the mouth. At Wire Orthodontics in
Spokane, WA, we use palatal
expanders to guide healthy jaw development in growing children.
What Is a Palatal Expander?
At Wire Orthodontics, a palatal expander is a custom orthodontic device that widens the upper jaw by gently separating the midpalatal suture, the cartilage seam between the two halves of the palate. Over several weeks, small daily adjustments create new bone in this space, expanding the arch to correct crossbites, relieve crowding, and improve overall alignment.
There are three common types of expanders Dr. Wire may recommend based on each child’s needs:
- Rapid Palatal Expander (RPE): Fixed to the upper molars and adjusted daily with a small key.
- Removable Expander: A retainer-style appliance used for milder cases.
- Surgically-Assisted Expander: Reserved for older teens and adults whose palatal suture has fused.
This appliance works best during childhood, while the bones of the upper jaw are still developing and easier to guide. That’s why palatal expanders are a key part of phase one treatment at Wire Orthodontics. Catching narrow-arch issues early often means a shorter, simpler treatment plan during the teen years and a more stable result long-term.
Benefits of Palatal Expanders
Palatal expanders correct crossbites, create room for crowded teeth, and often reduce the need for extractions later. Used at the right age, they can improve breathing in children who mouth-breathe, guide healthy jaw and facial development, and simplify future orthodontic care. One small appliance can shape the foundation for a healthier bite for years to come.
Here are the most common benefits of palatal expander treatment:
- Corrects crossbites by aligning the upper and lower arches properly.
- Creates room for crowded teeth, which often reduces the need for extractions later.
- Improves airway and breathing in some children, particularly those who mouth-breathe or snore.
- Simplifies future orthodontic care, often shortening time in traditional braces or Invisalign.
- Guides jaw and facial development during the critical growth years.
The American Association of Orthodontists notes that addressing skeletal issues like a narrow upper jaw early can prevent more complex problems from developing in adolescence. For many of our Spokane families, this means smoother treatment down the road and results that last long-term.
How Palatal Expander Treatment Works in Spokane
Palatal expander treatment begins with a free consultation and digital imaging, followed by fitting a custom appliance to the upper molars. Parents then turn a small key daily at home for two to four weeks to widen the jaw. A retention period of several months lets new bone stabilize before removal.
Treatment at Wire Orthodontics follows a clear, predictable process. From your first visit to your final reveal, Dr. Wire personally guides each step so you always know what to expect. Most children adapt to their expander within a few days, and the active phase is shorter than many parents anticipate.

Step-by-Step Breakdown
- Consultation and imaging. Dr. Wire evaluates your child’s bite, palate width, and developmental stage using 3D digital scans.
- Custom fitting. The expander is built to fit your child’s mouth precisely and attached to the upper back teeth.
- Daily activation. You’ll turn a small key in the center of the appliance once or twice a day, following Dr. Wire’s exact instructions.
- Active expansion phase. Lasting about 2-4 weeks, this stage may produce a small gap between the front teeth. That’s a good sign that the expander is working.
- Retention period. For several more months, the expander stays in place while new bone fills the expanded space.
Total wear time usually falls between 6 and 9 months. Because we’re a family-owned practice, you’ll see Dr. Wire at every visit, so the same familiar face greets you at every check-in.
Who Is a Good Candidate for a Palatal Expander?
The best candidates for a palatal expander are children between the ages of 7 and 12, when the upper jaw is still developing and the palatal suture has not yet fused. Early intervention during this window allows Dr. Wire to guide bone growth gently and effectively, often preventing more invasive treatment later.
A palatal expander may be the right choice if your child has:
- A crossbite, where the upper teeth fit inside the lower teeth when biting down.
- Trouble with a narrow upper palate that doesn’t match the width of the lower jaw.
- Dental crowding with not enough room for permanent teeth to come in straight.
- Signs of impacted teeth that need additional space to erupt properly.
- Breathing concerns related to a constricted upper arch.
Teens and adults can still benefit from expansion, though the process often requires surgically-assisted techniques because the palatal bones have fused. The American Association of Orthodontists recommends that every child have an orthodontic evaluation by age 7, which is exactly when many palatal issues can be identified and addressed with phase one treatment.

Palatal Expander FAQs
Do palatal expanders hurt?
Most children feel mild pressure or fullness for a few minutes after each turn, but it isn’t sharp pain. The sensation typically fades within 5-10 minutes. After the first few days, most kids forget the expander is even there.
How long do you wear a palatal expander?
Total wear time is usually 6-9 months. The active expansion phase lasts about 2-4 weeks, followed by a longer retention period of several months while new bone forms and stabilizes in the expanded area.
Can adults get palatal expanders?
Yes, but the process is different. Because the palatal suture fuses in early adulthood, adults usually need a surgically-assisted rapid palatal expander (SARPE) to achieve true skeletal expansion. Dr. Wire can discuss whether this is the right option during your free consultation.
Will my child have a lisp or trouble eating?
A short adjustment period is normal. Most children adapt their speech within a week and find a comfortable rhythm with eating shortly after. Sticking to soft foods for the first day or two helps a lot.
How much does a palatal expander cost in Spokane?
Costs vary depending on the type of expander and overall treatment plan. We’ll provide a clear, written estimate at your free consultation and review any insurance benefits and financing options that may apply.
How do I clean and maintain the expander?
Brush around the appliance carefully after meals and use a water flosser to rinse out food particles. Avoid sticky, hard, or chewy foods that could loosen the expander. Dr. Wire will walk you and your child through care instructions step by step at the fitting appointment.
