Does Your Child Need a Palatal Expander?
If your child’s upper jaw seems too narrow or if their teeth are overcrowded, they might benefit from a palatal expander. These orthodontic devices are commonly used to widen the upper jaw and are especially effective when used at a young age—typically between ages 6 and 12. At MacKenzie Orthodontics in Saint John, we often recommend expanders to correct crossbites, create space for erupting teeth, and support proper jaw growth.
What Exactly Is a Palatal Expander?
A palate expander works by gently pushing the two halves of the upper jaw apart at the midpalatal suture, allowing the body to fill in the space with new bone. This process, known as skeletal expansion, is usually well-tolerated by children and feels more like pressure than pain. Most kids adjust within a few days and don’t even notice it after a few weeks.
When and Why It’s Used
Expanders are most effective before puberty, when the bones are still growing and the upper jaw is flexible. They’re used to treat crossbites, overcrowding, and narrow arches. By widening the jaw early, we can often avoid the need for tooth extractions or more invasive treatments later on. We tailor the expansion rate based on your child’s age and growth stage, often turning the expander daily for younger kids or slowing down as they enter puberty.
What to Expect from the Process
Expanders can be banded or bonded to the back teeth and have a small screw in the center that’s turned with a special key. Some parents are surprised when a gap forms between the front teeth—but don’t worry, it usually closes on its own. Mild discomfort is common at first, but cold foods and reassurance help, and most kids adapt quickly.
