Palatal Expanders: A Parent’s Guide

What is a palatal expander?
A palatal expander is a small appliance that fits along the roof of the mouth and attaches to the back teeth. A tiny screw in the center is turned on a set schedule, gently widening the upper jaw at its natural growth seam.
Why it’s recommended
A narrow upper jaw can cause crossbites, crowding and even contribute to breathing issues. Expanding while a child is young creates room for permanent teeth and helps the upper and lower teeth fit together properly.
How it feels
Kids typically feel pressure across the nose and cheeks for a few minutes after each turn. Speech and eating may feel different for a few days, but most children adapt quickly. A small gap between the front teeth often appears — a normal sign the expander is working that usually closes on its own.
Timeline
Active turning usually lasts a few weeks, followed by a few months of the expander staying in place while new bone fills in. We’ll give you a simple calendar and check progress at each visit. Invisalign First is another option for some children.
