A palatal expander is a custom orthodontic device designed to gradually widen the upper jaw. This treatment is often recommended for patients whose upper jaw is too narrow to accommodate all of the permanent teeth or to align properly with the lower jaw. Expansion can also help correct crossbites and create the necessary space to reduce crowding, often preventing the need for future tooth extractions. By addressing jaw width at the right stage of development, expanders can promote long-term oral health and improved function.
How Palatal Expansion Works
A palatal expander applies gentle, consistent pressure to the two halves of the upper jaw, which are connected by a growth plate. This plate is still pliable in children and young teens, making it possible to guide the jaw into a wider shape before it fuses in adulthood. Once the device is placed in your mouth, it is typically activated by turning a small key at the center of the expander at regular intervals. Each turn slightly increases the tension, which in turn promotes gradual bone movement and new bone growth.
Types of Palatal Expanders
Depending on your needs and the stage of treatment, our orthodontist, Dr. Wire, may recommend a fixed or removable expander in Liberty Lake and Spokane, Washington. Fixed expanders are bonded to the teeth and remain in place for several months. These are commonly used in younger patients. Removable expanders, on the other hand, may be used in teens or adults for more mild expansion needs. We will walk you through the options during your consultation and help you understand what to expect at each step.
What to Expect During Treatment
Most patients adjust to their palatal expander within a few days. Some may feel pressure or tightness in the upper jaw, nose or teeth, especially right after the appliance is activated. These sensations typically subside quickly. Over time, you may notice a gap developing between your front teeth — this is a normal part of the process and often closes as treatment progresses. Oral hygiene and dietary instructions will be provided to help keep your appliance and teeth clean.
Benefits of Expansion
Orthodontic expansion can improve your bite, breathing and appearance. It is especially valuable in young patients, as it can reduce the need for future orthodontic interventions. Expansion may also aid in airway development, particularly for children who experience mouth breathing or snoring. Creating proper jaw alignment early supports better long-term results and helps ensure that your teeth have the space they need to function and look their best.
