ProviderWhat is Palatal Expansion?
Palatal expansion is an early orthodontic treatment that widens a narrow upper jaw, allowing more space for permanent teeth to erupt and helping support healthy bite development.
In children, the upper jaw is made up of two halves connected by a growth suture; because it has not yet fused, a palatal expander can help widen the upper jaw, helping overcome any concerns such as crowding, crossbites, and insufficient space for incoming teeth.
For some children, expanding the upper jaw may also improve oral function, making it easier to chew, speak, or breathe comfortably.
The Importance of Orthodontics for Kids
Children with developing orthodontic issues can often benefit from early orthodontic intervention to prevent or reduce the need for more extensive treatment later in life. Palatal expansion, braces, or clear aligners may be part of your child's early orthodontic treatment at Cory Liss Orthodontics.
How Palatal Expanders Work
Palatal bones continue to grow until children reach puberty, making the years between five and 11 the ideal time to detect and treat a narrow palate.
A palatal expander is a custom-made orthodontic appliance that is designed to gradually widen the upper jaw, creating additional space for permanent teeth and supporting healthy jaw development. It can help correct crossbites, reduce crowding and improve overall bite alignment.
For many patients, palatal expanders remain in position during Phase 1 treatment. To activate the appliance, parents are typically instructed to turn a small expansion key at specific intervals, allowing the upper jaw to widen gradually over the course of treatment. Your orthodontist will provide detailed instructions and monitor your child's progress to ensure treatment remains on track.
