Can Adults Get Palate Expanders?
April 25, 2025
Palate expanders have long been associated with orthodontic treatment in children and adolescents. Traditionally, these devices are used during the early stages of development to gently widen the upper jaw, correcting bite alignment issues and creating space for proper tooth eruption. Because a child’s jaw is still growing and more malleable, this type of intervention is typically straightforward and highly effective.
However, the need for palatal expansion doesn't disappear with age. Many adults experience dental and orthodontic concerns that stem from a narrow upper jaw, such as crossbites, overcrowded teeth, and even breathing issues related to restricted nasal airflow. Fortunately, advancements in modern orthodontics have made it possible for adults to benefit from palatal expanders as well—albeit through different techniques and tailored approaches.
At Parsons Orthodontics, we specialize in comprehensive, patient-focused care that includes evaluating whether adult palatal expansion may be the right solution for improving both dental health and overall quality of life.
Understanding Palatal Expansion
What is a Palate Expander? A palate expander is a custom-made orthodontic device designed to gradually widen the upper jaw, also known as the maxilla. It typically fits in the roof of the mouth and applies gentle pressure on the upper molars through a central screw mechanism or other force-delivery systems. By turning the device incrementally—usually daily—the bone and surrounding tissue in the palate begin to shift and adapt, expanding the arch over time.
In younger patients, the expansion process takes advantage of the fact that the palatal suture (the seam where the two halves of the upper jaw meet) has not yet fused, allowing for relatively quick and straightforward adjustments. In adults, where the suture is fully formed, specialized expanders or surgical support may be required to achieve similar results.
Why Consider Palatal Expansion? A narrow upper jaw can contribute to a variety of dental and health-related issues. Some of the most common reasons to consider palatal expansion include:
- Crossbites – When the upper teeth bite inside the lower teeth rather than outside, causing uneven wear and potential jaw pain.
- Overcrowding – Limited space in the upper arch can lead to overlapping or crooked teeth, making oral hygiene more difficult and increasing the risk of cavities or gum disease.
- Breathing Difficulties – A constricted palate can affect the nasal passages, potentially contributing to mouth breathing, snoring, or even sleep apnea in some cases.
Addressing these issues through palate expansion can lead to improved bite alignment, enhanced facial symmetry, and even better airway function. Whether you're seeking cosmetic improvement or relief from functional problems, understanding your options is the first step toward a healthier, more confident smile.
Palate Expanders for Adults
If you're an adult wondering whether it's too late for a palate expander to help with your smile or bite, the good news is—it’s not. While it's true that palatal expanders are most commonly used in children and teens, adults can absolutely benefit from them too. The process just looks a little different.
As we age, the bones in our face become more set, including the upper jaw. In children, the two halves of the palate haven’t fully fused yet, which makes it easier to guide growth with a standard expander. In adults, that natural flexibility is gone, but that doesn’t mean expansion is off the table—it just means orthodontists take a more customized approach.
Depending on your needs, your orthodontist might recommend one of a few different solutions:
- Surgically Assisted Rapid Palatal Expansion (SARPE): This is a combination of orthodontic treatment and minor oral surgery. It’s a good option for adults with more significant crowding or bite issues. After the surgical step, a special type of expander is used to widen the palate gradually.
- Mini-Implant Assisted Rapid Palatal Expansion (MARPE): Think of this as a more modern, non-surgical option for some adults. Small temporary implants help anchor the expander directly to the bone, applying precise pressure where it’s needed.
- Mild Expansion with Traditional Devices: In cases where only a small adjustment is needed, your orthodontist might still be able to use a traditional expander—especially if your jaw still has a little natural flexibility.
Each option comes with its own pros and cons, and the best approach really depends on your unique dental anatomy and goals. That’s why an in-person consultation is so important. At Parsons Orthodontics, we take the time to evaluate your situation in detail and guide you toward the right treatment plan for long-term success.
Benefits of Adult Palatal Expansion
You might be wondering—if I’ve made it this far in life without expanding my palate, is it really worth doing now? The answer often surprises people. Expanding the upper jaw isn’t just about making room for straighter teeth. It can have a real impact on your comfort, confidence, and even your health.
Here are some of the key benefits adults can experience from palate expansion:
- Better Bite Alignment
A narrow upper jaw can throw your bite off, leading to uneven wear on your teeth or discomfort when chewing. Expansion helps create a more balanced bite, reducing stress on your jaw joints and making eating feel more natural. - More Room, Less Crowding
When teeth are competing for space, they tend to overlap or shift out of place. By widening the upper arch, an expander creates more room, which can make straightening your teeth more effective and often shorten the time you’ll need braces or aligners. - Easier Breathing
This one surprises people the most. A narrow palate can actually contribute to breathing problems, especially during sleep. Expanding the palate may help open up the nasal passages, leading to improved airflow and, in some cases, relief from snoring or mild sleep apnea symptoms. - Improved Facial Balance
Though it’s not the main goal, widening the palate can subtly enhance facial symmetry and structure—something patients often appreciate once treatment is complete.
Whether your motivation is functional or cosmetic—or a bit of both—palatal expansion can be a powerful step toward a healthier smile and better quality of life. And when it’s done by a team that truly understands adult orthodontics, like the specialists at Parsons Orthodontics, you’re in the best possible hands.
Considerations and Risks of Palatal Expansion in Adults
While adult palate expansion can offer some amazing benefits, it's important to understand that the process isn’t without its challenges. Like any orthodontic treatment, it comes with a few key considerations—and knowing what to expect can help you feel more confident about your decision.
Longer Treatment Time
Because adult bones are fully developed and less flexible than a child’s, the expansion process can take a bit longer. This doesn’t mean it’s less effective—just that it requires a little more patience. The timeline varies from person to person, especially if your treatment includes surgical assistance or other orthodontic work alongside the expander.
Possible Discomfort
As with any orthodontic appliance, you may experience some pressure or soreness, especially in the early days of wearing your expander. Most people describe it as more of an adjustment than a pain, and it usually subsides as your mouth adapts. If surgery is part of your plan, mild post-operative discomfort is also normal and manageable with your care team’s guidance.
Surgical Support May Be Needed
In many adult cases, expanding the palate without surgery isn’t always possible. Your orthodontist might recommend SARPE (Surgically Assisted Rapid Palatal Expansion) or another method that involves minor oral surgery to help make room for the expansion. While the word "surgery" can sound intimidating, it's typically a straightforward, well-planned procedure with predictable outcomes and a smooth recovery when done by experienced professionals.
Temporary Changes in Speech or Eating
Some patients notice slight changes in the way they speak or chew while adjusting to their expander. These effects are temporary and usually resolve quickly as you get used to the device.
A Commitment to Oral Hygiene
Because expanders sit in the roof of your mouth, they create extra surfaces that need to be cleaned daily. Good brushing and rinsing habits become even more important during treatment to prevent plaque buildup or gum irritation.
