Palatal Expansion Explained: Benefits for Adults and Children
Palatal expansion is a treatment used to widen the upper jaw (maxilla) by gradually separating the mid-palatal suture. This allows for better alignment of the teeth, improved breathing through the nose, and better tongue posture. While it's commonly used in children, new technology and protocols have made adult palatal expansion possible—with life-changing results.
Why Widen the Palate?
A narrow palate doesn't just cause dental crowding—it often contributes to mouth breathing, poor sleep, snoring, and even facial imbalance. Widening the palate can help restore natural oral and facial function.
Benefits of Palatal Expansion
-
Improved Nasal Breathing: Expanding the upper jaw also expands the nasal floor, increasing airflow and reducing nasal resistance.
-
Better Sleep and Airway Function: By creating more room for the tongue and improving airflow, palatal expansion can help reduce symptoms of UARS and mild obstructive sleep apnea.
-
Facial Development: In children, palatal expansion can improve midface growth and correct narrow or sunken facial features. In adults, it can improve cheek support and facial symmetry.
-
Dental and Orthodontic Benefits: It creates space in the arch, reducing the need for tooth extractions and helping align the bite properly.
-
Tongue Posture and Oral Function: A wider palate supports better tongue posture, which in turn supports healthy swallowing, speech, and facial tone.
Palatal Expansion in Children vs. Adults
| Aspect | Children | Adults |
|---|---|---|
| Growth Plate Open? | Yes (suture is flexible) | No (suture is fused) |
| Device Used | Rapid Palatal Expander (RPE) | MARPE, MSE, or bone-borne expanders |
| Timeline | 3-6 months | 6-12 months or longer |
| Goals | Guide facial growth | Correct structural issues |
| Surgical? | No | Sometimes, or advanced devices used |
Is Adult Palatal Expansion Really Possible?
Yes! With the advent of devices like the MSE (Maxillary Skeletal Expander) and FME (Facegenics Midface Expander), adults can now achieve true skeletal expansion. These use TADs (Temporary Anchorage Devices) anchored to the palate to widen the bone safely.
It's critical, however, to work with a trained airway orthodontist—not all providers understand how to safely perform adult expansion or monitor changes to breathing and function.
Conditions That May Improve with Palatal Expansion
- Mouth breathing
- Nasal congestion
- Snoring and mild sleep apnea
- High-arched palate
- Dental crowding
- Recessed midface
- Narrow smile or facial asymmetry
- Poor tongue posture and swallowing issues
How Long Does It Take?
- Children: Expansion usually occurs over 1-2 months, followed by several months of retention.
- Adults: Progress is slower—6 to 12 months or more, depending on the method and goals.
Retention appliances are worn afterward to maintain the expansion, and additional therapies like myofunctional therapy are often recommended for long-term success.
Frequently Asked Questions
Does palatal expansion hurt?
Most people report mild pressure but not sharp pain. Children typically adjust quickly. Adults may experience discomfort for a few days after each adjustment.
Is surgery required for adults?
Not always. Devices like MSE and FME can provide non-surgical expansion in many adult cases. In more complex cases, SARPE (Surgically Assisted Rapid Palatal Expansion) may be considered.
Can it change my face?
Yes. In both adults and children, expansion can enhance facial symmetry, widen the smile, and support the cheeks and eyes.
Is it permanent?
With proper retention and follow-up care, results can be long-lasting.
Conclusion: A Life-Changing Treatment at Any Age
Palatal expansion isn't just for crowded teeth—it's a foundational treatment that can impact breathing, posture, sleep, and appearance. Whether you're a parent considering early intervention or an adult seeking answers for your symptoms, expansion might be the missing piece.
