Is your child experiencing crowded teeth, breathing difficulties, or a crossbite? These common issues often stem from a narrow upper jaw that requires specialized orthodontic attention. At Park Smiles NYC, our board-certified orthodontist, Dr. Helen Choi, provides expert rapid palatal expander treatment in a comfortable, child-friendly environment on Manhattan’s Upper East Side.
A rapid palatal expander (RPE) is a specialized orthodontic appliance designed to widen a narrow upper jaw in growing children. This custom-made device works with your child’s natural growth patterns to gently separate the two halves of the palate along the midline suture, creating additional space for proper teeth alignment and improved airway function.
Unlike traditional braces that primarily move teeth, an RPE actually modifies the bone structure of the upper jaw. This orthopedic approach addresses underlying skeletal issues rather than simply shifting teeth’s position. By expanding the palate during childhood when growth is most adaptable, we can often prevent more complex orthodontic issues later, potentially reducing the need for extractions or extensive treatment during adolescence. The palate expander helps create more space for permanent teeth and addresses severe crowding before it becomes problematic.
Give your child the foundation for a healthy, beautiful smile with expert palatal expansion. Early intervention can prevent more complex issues later.
Palatal expansion treatment offers numerous advantages beyond simply creating space for crowded teeth. By widening the upper jaw during childhood development, we establish a proper foundation for oral health and function that benefits patients for life.
The most immediate benefit is creating adequate space for permanent teeth to emerge properly aligned, potentially reducing or eliminating the need for extractions later and preventing impacted teeth. Many parents notice improved breathing in their children following expansion, as the widened palate creates more space in the nasal airway—particularly beneficial for children who experience mouth breathing or sleep-disordered breathing, including sleep apnea and snoring.
Palatal expansion often corrects crossbites, where upper teeth sit inside lower teeth, preventing uneven jaw growth and asymmetrical facial development. The treatment may also improve speech articulation for some children and create better arch form for a more aesthetic smile.
When performed at the optimal age while the midpalatal suture remains flexible, expansion treatment is generally comfortable and efficient, avoiding more invasive treatments and surgery that might be necessary if these issues remain untreated into adulthood.
Crossbite correction: In a young patient with a narrow palate, the upper teeth can bite inside the lower teeth on one side or both, which may cause eventual lower-jaw displacement and/or unfavorable jaw growth. The expander helps to correct this problem by expanding the upper jaw as an early intervention, achieving the desired width needed for proper alignment.
Eliminates or reduces overcrowding: Palatal expansion enables your child’s upper teeth to erupt in their correct positions, providing adequate room for developing teeth.
Improves breathing: A narrow or deep jaw makes it difficult for a child to breathe through his or her nose. This can result in continuous mouth breathing, known to be detrimental to dental health and create sleep disorders. The expander helps provide easier breathing due to the expansion of the palate and nasal passages. In most cases, improved airway function is noticed within the first few weeks of treatment.
The RPE is custom-made to fit exactly for each patient’s mouth and teeth. It is a non-removable appliance fixed onto the first molars (or upper molars) of the upper arch and covering over most of the palate. An RPE can also be removable depending on the treatment plan. The appliance consists of two halves connected in the middle with a screw. Using a special key, turning the screw will induce controlled tension at the intersection of the two palatal bones.
This tension will gradually move the two bones apart, expanding the palate to the desired width. At the time of the desired expansion, your orthodontist will leave the expander in for a couple more months to give your child’s bones time to adapt and stabilize the new expansion. During this phase, new bone forms in the palatal suture area, permanently maintaining the increased width.
The rapid palate expander works efficiently, typically achieving the desired expansion in a relatively short time compared to other orthodontic treatments. Several different types of palate expanders are available, and Dr. Choi will determine which option is best for your child based on their specific needs.
The palatal expander features a metal framework that sits comfortably against the roof of the mouth. Parents are provided with a special key used to activate the expander according to a precise schedule. Each turn of the key creates controlled pressure that gently separates the palatal suture, allowing the jaw bones to gradually widen. This procedure is straightforward, and most children adapt quickly to the activation routine. We provide detailed instructions and support throughout the expansion phase to ensure parents feel confident managing their child’s treatment.
Our Upper East Side practice specializes in creating positive dental experiences for children of all ages. We understand that young patients have unique needs and concerns, which is why we take extra time to explain procedures in age-appropriate language, demonstrate tools, and address any anxiety. Our team has extensive experience working with children, creating a warm, welcoming environment that turns dental visits into positive experiences.
Unlike practices offering only orthodontic services, Park Smiles NYC provides truly integrated care through our team of specialists.

This comprehensive approach ensures all aspects of your child’s oral development are considered, creating harmony between orthodontic treatment and overall dental health.

Your child’s treatment benefits from our investment in cutting-edge diagnostic and treatment technology. Digital imaging provides detailed visualization of palatal development with minimal radiation exposure, while our custom fabrication ensures appliances fit comfortably and function efficiently. These technological advantages translate to more predictable outcomes and a more comfortable experience throughout the expansion process.
At Park Smiles NYC, we’ve refined our palatal expansion process to ensure effectiveness and comfort for our young Manhattan patients.
The journey begins with a comprehensive evaluation where Dr. Choi assesses your child’s palate width, dental development, and breathing patterns using digital imaging and clinical examination. Based on these findings, she creates a customized treatment plan tailored to your child’s specific needs and growth patterns.
Next, we take precise impressions or digital scans to create a custom-fitted expander. When the appliance is ready, Dr. Choi carefully places it, providing detailed instructions for activation and care. The active expansion phase typically lasts 2-4 weeks (or a few weeks), during which parents turn the expander’s key according to our specific schedule.
After achieving the desired expansion, the appliance remains in place for several months while new bone forms in the expanded space. Throughout treatment, we schedule regular monitoring appointments to ensure optimal progress and make any necessary adjustments.
Once stabilization is complete, we remove the expander and evaluate whether additional orthodontic treatment is needed or if retainer wear is sufficient to maintain the results.
Your child will likely experience mild discomfort during the beginning of the treatment period, probably more so due to the actual presence of the appliance inside the mouth than expansion, but this is a normal sign that the expander is working as intended. It’s important to remember that the uncomfortable experiences are only temporary and will lessen as your child’s body adapts to the appliance. Some of the issues your child may expect could include:
Soreness
A feeling of pressure
Speaking and eating feel a bit awkward at first
A slight gap between the front teeth
These symptoms typically resolve within the first few days as your child adjusts to the appliance. The procedure is designed to be as comfortable as possible, and any discomfort is temporary and manageable.
Palatal expansion is most effective when performed before the midpalatal suture fuses, typically before puberty. For most children, the ideal window is between ages 7-14, though individual development varies. Earlier intervention generally allows for more efficient expansion with less discomfort. During your consultation at our Manhattan office, Dr. Choi will evaluate your child’s specific development to determine optimal timing for maximum effectiveness and comfort. In most cases, treating developing jaws during the growth phase yields the best long-term results and may prevent the need for more invasive treatments or surgery later.
While some patients may experience mild pressure and soreness, especially during the first few days, palatal expansion is generally well-tolerated by children. The sensation is often described as feeling pressure rather than pain. Most children adapt quickly to the appliance and the activation process. Any discomfort typically subsides within a short time as the mouth adjusts. We provide detailed care instructions and are always available to address concerns throughout the treatment phase. The benefits of early intervention far outweigh the temporary adjustment period.
The active expansion phase with the rapid palatal expander typically lasts 2-4 weeks, during which the key is turned according to a specific schedule to gradually widen the palate. However, the expander remains in place for several additional months (usually 3-6 months) to allow new bone to form and stabilize the expansion. The total treatment time varies based on each child’s individual needs and growth patterns. Dr. Choi will provide a detailed timeline during your consultation and monitor progress throughout the procedure to ensure optimal results. The halves of the palate gradually separate and stabilize, creating permanent width that accommodates proper teeth alignment and improved breathing.
