An orthodontic expander is a device that gently widens the upper jaw to create space, improve bite alignment, and support airway health. At Miles of Smiles, we provide expanders for children, teens, and even adults, including advanced orthodontic palatal expanders. Expanders are often used in conjunction with additional orthodontic treatment.

Where Do Orthodontic Expanders Fit In?
What Dental Expanders Do
Expanders are commonly used for:
- Widening narrow upper jaws
- Creating room for permanent teeth
- Supporting cross-bite treatment options
- Improving breathing and airway function
This makes orthodontic palatal expanders especially effective for early malocclusion treatments.

How Orthodontic Expanders Work
- Placement – A custom expander is attached to the upper molars.
- Active Treatment – A small key is used to gradually widen the appliance over time.
- Growth Guidance – We will monitor expansion and adjust as needed to ensure proper jaw growth
- Completion – Expansion is usually complete in 3–6 months and may be the first step in further orthodontic treatment
Adults may also benefit from orthodontic expander for adults, though treatment may take longer.
