Palatal Expanders & Orthodontic Appliances in Mililani
Reviewed by Dr. David Dung, board-certified orthodontist
Orthodontic treatment isn’t only about braces. Especially in early (Phase I) treatment, our board-certified orthodontists use specialized appliances to guide a child’s growth, create space, and set up the best possible result. Here’s a plain-language guide to the appliances we use at Mililani Orthodontics, what each one does and why it might be part of your child’s plan.
Rapid Palatal Expander (RPE)
A rapid palatal expander, or RPE, gently widens the upper jaw in a growing child. It’s used to correct a crossbite (when upper teeth bite inside the lower teeth) or a narrow upper arch, and to create room for permanent teeth, which can reduce crowding later. An RPE is typically worn for about six to nine months.
How an RPE is adjusted: the expander is widened a tiny amount at a time using a small key. Your orthodontist will demonstrate the exact technique and how often to turn the key for your child’s specific appliance, and send you home with clear written instructions. Never adjust the expander more often than your orthodontist directs.
RPE With Reverse-Pull Facemask
For children with an underbite or an underdeveloped upper jaw, an RPE can be paired with a reverse-pull facemask. Worn mostly at home and overnight during early treatment, it gently encourages the upper jaw to grow forward at the ideal age, often reducing the need for more involved treatment later.
Space Maintainer
When a baby tooth is lost too early, neighboring teeth can drift into the gap and block the permanent tooth. A space maintainer holds that space open so the adult tooth can come in properly, a simple step that can prevent bigger problems down the road.
Forsus Appliance
The Forsus appliance is a fixed device that helps correct bite problems (often an overbite) by gently guiding the jaw into better alignment. It works alongside braces and is a comfortable, lower-profile alternative to traditional headgear.
Temporary Anchorage Device (TAD)
A TAD is a small, temporary anchor that gives the orthodontist a fixed point to move specific teeth precisely, making certain corrections faster and more predictable. TADs are placed gently and removed when their job is done.
Retainers
After treatment, a Hawley retainer (a custom acrylic-and-wire retainer) or a clear Essix retainer keeps your new smile in place. Retention is essential. Learn more on our retainers page.
Do You Need an Orthodontist for a Palatal Expander?
Yes, appliances like expanders involve careful diagnosis and timing, which is the training of an orthodontic specialist. Every doctor at Mililani Orthodontics is a Diplomate of the American Board of Orthodontics, and we plan appliance treatment using comfortable iTero® digital scans. Costs vary by appliance and are often covered in part by orthodontic insurance. We’ll review your specifics and file your claim.
Frequently Asked Questions
At what age does a child get a palatal expander?
Expanders work best while a child is still growing, often between ages 7 and 11. The American Association of Orthodontists recommends a first orthodontic check by age 7 so we can catch issues like a narrow arch or crossbite at the ideal time.
How do you adjust a rapid palatal expander?
Using a small key, you turn the expander a tiny amount on the schedule your orthodontist gives you, usually once or twice a day for a set period. We show every family exactly how, and we’re a phone call away if you have questions.
