The Invisalign Palatal Expander System is a new, technology-driven option used to gently widen a child’s upper jaw. Using advanced digital imaging and 3D printing, these expanders are custom designed to fit your child’s mouth with exceptional accuracy, improving comfort and treatment precision.
Instead of relying on traditional molds, the Invisalign Palatal Expander System is created using iTero® digital scans of your child’s teeth and jaw. This allows your orthodontist to design appliances that fit precisely and function exactly as planned. The result is a more comfortable fit and predictable expansion.
Like Invisalign clear aligners, which use a series of aligners to encourage tooth movement, the Invisalign Palatal Expander System uses a series of 3D-printed expanders that gradually widen the upper jaw to create space for adult teeth. Each expander is worn for several weeks before being replaced by the next expander in the series.
Why would kids need palatal expander treatment?
Palatal expansion may be recommended when a child’s upper jaw is too narrow to allow the teeth and bite to develop properly. Because children are still growing, early treatment can:
- Create room for incoming permanent teeth
- Improve bite alignment
- Support healthy facial growth
- Reduce the need for tooth extractions or more extensive treatment later
Why are Invisalign expanders different?
Clinically proven to be safe and effective.
The Invisalign Palatal Expander System is the only FDA-cleared, removable palatal expander shown to be just as effective as traditional expanders, giving parents confidence in a modern approach to treatment.1
Removable for easier oral hygiene.
With no metal or wires, your child can simply remove the expander to brush and floss normally, helping keep teeth and gums clean throughout treatment.
Designed with comfort in mind.
Each expander is custom-fit to your child’s mouth and 3D printed for a smooth, low-profile design that feels more natural and comfortable to wear.
Kid-friendly and easy to use.
Most children are able to put the expander in and take it out on their own, making daily routines simpler and less stressful for the whole family.
No food restrictions.
Since the expander is removable, kids can enjoy their favorite foods without worry. Meals stay familiar, and cleaning the expander is quick and easy with a toothbrush.
Fewer unexpected visits.
Without metal or wires, there’s less risk of breakage, meaning fewer emergency appointments and more uninterrupted time for school, sports, and play.
The Invisalign Palatal Expander System combines proven orthodontic techniques with modern technology. For children who need jaw expansion, this approach allows your orthodontist to plan treatment carefully and deliver results that support healthy development, function, and long-term oral health.
