Palatal Expander in West Hills

A palatal expander in West Hills is a common orthodontic appliance for children that gently widens the upper jaw (the palate). Because a child's jaw is still growing, a small, gradual expansion can create room for crowded teeth and correct a narrow bite, often making later treatment simpler.

What a palatal expander fixes

• A crossbite caused by a narrow upper jaw.
• Severe crowding, by creating space for adult teeth.
• A narrow smile or limited room in the arch.

How it works

The expander is fixed to the upper back teeth. Using a small key, you make tiny daily adjustments at home for a few weeks, which we will show you exactly how to do. The jaw widens gradually and comfortably, then the appliance stays in place a while longer to hold the new width.

Timing matters

Palatal expansion works best while a child is still growing, which is one reason the American Association of Orthodontists recommends a first check-up by around age 7. At a consultation we will tell you whether an expander is needed now or whether it is better to wait.
