Palatal Expander
A palatal expander is an orthodontic appliance commonly used in children to widen the upper jaw and improve bite alignment. At Dr. Doug Orthodontics, palatal expansion is carefully planned to support healthy jaw development, reduce crowding, and correct crossbites during growth.
What Is a Palatal Expander?
A palatal expander is a custom appliance that gently widens the upper jaw, also called the maxilla. It works through small daily activations that gradually create more space in the upper arch. Palatal expanders are most effective in younger patients because the upper jaw is still developing and responds more easily to expansion.
Why Is a Palatal Expander Recommended?
A palatal expander may be recommended when the upper jaw is narrower than the lower jaw. This imbalance can lead to bite problems and crowding if left untreated.
Palatal expansion can help:
- Correct posterior crossbites
- Create space for erupting permanent teeth
- Reduce dental crowding
- Improve overall bite alignment
- Support proper jaw development
In some cases, widening the upper jaw may also help reduce symptoms associated with a narrow airway, such as mouth breathing or snoring.
How Does a Palatal Expander Work?
The expander is activated with a small key that is turned daily according to Dr. Doug’s instructions. Each turn applies gentle pressure to widen the upper jaw over time. Once the desired expansion is achieved, the appliance remains in place for an average of six months to allow the bone to stabilize and maintain the new width.
How Do I Activate the Palatal Expander?
The visuals and video provided on this page are designed to guide you through the activation process. Follow these steps carefully each day.
Step 1
In a well-lit area, tip the patient’s head back.
Step 2
Place the key in the hole until it is firmly in place.
Step 3
Push the key toward the back of the mouth. You will notice the fender will rotate and the new hole will appear. The rotation stops when the key meets the back of the expander.
Step 4
Press back and down toward the tongue to remove the key. The next hole for insertion of the key should now be visible.
How Long Does a Palatal Expander Stay In?
The active expansion phase typically lasts a few weeks, depending on the amount of widening needed. After expansion is complete, the appliance stays in place for several additional months to stabilize the results before it is removed.
Schedule a Consultation
If your child has a crossbite, crowding, or jaw alignment concerns, a palatal expander may be an important part of early orthodontic care.
Contact Dr. Doug Orthodontics to schedule a consultation and learn whether palatal expansion is right for your child’s smile.
Frequently Asked Questions
Parents often have questions about palatal expanders and what to expect during treatment. These answers provide helpful guidance.
Does Activating the Expander Hurt?
Most patients feel pressure rather than pain. Any discomfort is usually mild and temporary, especially during the first few days of activation.
Will There Be a Gap Between the Front Teeth?
Yes. A temporary space between the upper front teeth is normal and expected during expansion. This gap typically closes on its own or is addressed with orthodontic treatment.
How Old Does My Child Need to Be for a Palatal Expander?
Palatal expanders are most effective in younger children, but Dr. Doug will determine the appropriate timing based on growth and development.
Will My Child Have Trouble Speaking or Eating?
There may be a short adjustment period, but most children adapt quickly to the appliance within a few days.
