Orthodontic treatment often includes a palatal expander, but many parents don’t know much about them! At Atlanta Orthodontic Specialists, we understand that every parent wants to be fully informed about every aspect of their child’s orthodontic care.
So, we put this page together to answer all your questions about palatal expanders so you can make the right choices for your child’s orthodontic health.
A palatal expander has either two or four rings or “bands” that are wrapped around a tooth on either side of your child’s mouth. In the middle of the expander is a small gear. With your help, your child will insert and turn a key in the gear every so often (according to the doctor’s advice) to slightly increase the outward tension of the expander. With each turn, the increased tension gradually spreads the palate apart to create more space for incoming teeth.
Instead of a “gear” that is turned every night, the quad helix has four loops (or helices) that essentially make this type of expander a large spring. When inserted, the orthodontist takes the appliance and widens these loops. That way, once the appliance is in place, it will provide a constant and gentle pressure to widen the palate and teeth. Unlike a “Hyrax” expander, this appliance is adjusted only by the orthodontist at regular visits.
Timing expander treatment is very important. Palatal expanders should ideally be used before the two separate plates of the palate fuse together in puberty (around age 14-16). Because of this, expanders may be recommended as early as 6-10 years old, as they typically work best on younger children. Expansion on younger patients is easier, and there are more options in terms of the type of expanders that we use. If done early, expansion can be simpler and more effective. Sometimes, expansion may be delayed until more permanent teeth erupt (12-14 years old), but it is important to begin treatment with an expander prior the fusion of the upper palate bones.
Our doctors will examine your child’s mouth, x-rays and development before recommending an expander. Not every child needs one to have straight teeth!
Invisalign’s convenient tooth-straightening process is only three steps.
How long will my child wear an expander?
Every child is different, but on average, you can expect your child to wear an expander for 6 to 8 months. Braces may be used during this time as needed to help straighten the teeth.
Is wearing an expander uncomfortable?
As the expander widens, your child will feel pressure and possibly mild discomfort in their mouth initially. That discomfort dissipates with each day as the bones and cartilage of the palate move into place. If necessary, OTC pain relievers can help with any discomfort that comes from wearing the expander.
