Rapid Palatal Expanders in Wilmington, NC
Cape Fear Smiles offers rapid palatal expanders in Wilmington, NC as part of our airway-focused orthodontic approach. Dr. Norma Cortez and Dr. Adrian Soto use palatal expansion to widen narrow upper jaws, create space for proper tooth alignment, and improve nasal airway volume for better breathing.
Rapid Palatal Expanders Explained
A rapid palatal expander (RPE) is a fixed orthodontic appliance that gradually widens the upper jaw by applying gentle outward pressure. In growing children, the mid-palatal suture has not yet fused, allowing the jaw to be expanded naturally. This creates more room for teeth, improves the bite relationship, and increases the volume of the nasal airway.
Benefits of Rapid Palatal Expansion
- Widens the upper jaw to resolve crossbites and crowding.
- Increases nasal airway volume for improved breathing.
- May reduce mouth breathing, snoring, and sleep-disordered breathing.
- Creates space for erupting permanent teeth without extractions.
- Guides healthy facial development during growth years.
- Relatively short active treatment phase of two to four weeks.
The Treatment Process
After a thorough evaluation and imaging, the RPE is custom-fabricated and cemented to the upper molars. A small key is used to activate the device, typically once or twice daily. Each activation produces approximately 0.25mm of expansion. After the desired width is achieved, the device remains in place for several months while new bone fills in the expanded suture.
What to Expect
Children typically adapt to the expander within a few days. A temporary gap between the front teeth is normal and indicates the expansion is working—it closes naturally as treatment continues. Mild pressure after each activation is normal and brief. Parents receive detailed instructions on the activation schedule.
