How it works
How it works
A jaw expander gently widens the upper jaw to create room for teeth and correct a narrow bite.
Fitted to the roof of the mouth, an expander applies gentle, steady pressure that encourages the jaw to widen over a few months. It works best while the jaw is still growing, which is why it’s most common in children and younger teens.
Creating space early can reduce crowding and may mean simpler treatment — or none at all — later on.
