Orthodontic Expanders in Newport Beach, CA
Creating Room for a Healthy, Well-Aligned Smile
For younger patients or anyone with a narrow arch, an orthodontic expander can create more space in the mouth and help guide proper jaw development. Dr. Omid Haroonian evaluates your child’s teeth and bite and lets you know whether an expander belongs in their treatment plan.
What Is an Orthodontic Expander?
An orthodontic expander, often called a palatal expander, is a custom appliance that gradually widens the upper arch. It fits against the roof of the mouth and is anchored to the upper back teeth. A small adjustment mechanism in the center is turned on a set schedule, applying gentle, steady pressure that widens the arch a little at a time. Expanders are most often used for younger patients, whose jaws are still developing, and for patients with narrow arches. By creating more space, an expander can help the adult teeth come in with more room and reduce the need for extractions later in life.
How Expanders Help
- More space. Widening a narrow arch creates more room in the mouth for the teeth.
- Jaw development. An expander helps guide proper jaw development while the jaw is still growing.
- Fewer extractions. Making room early can reduce the need for extractions later in life.
Part of a Complete Orthodontic Plan

Frequently Asked Questions About Orthodontic Expanders
- What does an orthodontic expander do?
An orthodontic expander widens a narrow upper arch to create more space in the mouth. That extra room helps guide proper jaw development. It can also reduce the need for extractions later in life. Dr. Haroonian will explain what an expander would do for your child’s smile.
- Who needs an expander?
Expanders are most often recommended for younger patients or for patients with narrow arches. Whether one is needed depends on the shape of the arch, the bite and the space available for the teeth. Dr. Haroonian evaluates all of this at an orthodontic consultation. He will let you know whether an expander is part of the right plan.
- When should my child have an orthodontic screening?
Orthodontic screening is recommended around age 7. An early look lets us see how the jaw and teeth are developing. Treatment can begin at any age depending on need. A screening simply tells you where things stand.
- How does an expander work?
An expander fits against the roof of the mouth and is attached to the upper back teeth. A small mechanism in the center is adjusted on a set schedule. Each adjustment widens the arch a little at a time with gentle, steady pressure. We will show you exactly how and when to make adjustments.
- What happens after expansion?
After an expander has done its work, many patients move on to braces or clear aligners to straighten the teeth. Once treatment is complete, a retainer keeps the smile aligned and stable. Teeth can shift over time without retention. We will guide you through each phase of the plan.
