Why Thousands of Adults Are Expanding Their Jaw Instead of Pulling Teeth! (MARPE - Palatal Expansion)

5 Things Everyone in Toronto & Guelph Should Know About MARPE

Most people think orthodontics is about straight teeth.

What if it could also influence how you breathe, sleep, and even how your jaw develops?

That's why more teens and adults are asking about MARPE (Mini-Screw Assisted Rapid Palatal Expansion)—an advanced orthodontic treatment that expands the upper jaw at the skeletal level instead of simply moving teeth.

At Westwood & Starwood Dental, we use airway-focused dentistry to help patients improve not only their smiles, but also healthy breathing and long-term oral function.

If you've been told you have crowded teeth, a narrow palate, mouth breathing, or snoring, here's what you should know.

What is MARPE?

MARPE (Mini-Screw Assisted Rapid Palatal Expansion) is an advanced orthodontic treatment that gently widens the upper jaw using small Temporary Anchorage Devices (TADs) rather than relying only on the teeth.

Unlike traditional expanders, MARPE creates skeletal expansion, helping increase space within the palate while supporting healthy jaw development.

Today, many providers—including our team—use slow expansion protocols, making treatment more comfortable while minimizing the large front-tooth gap often associated with older rapid expansion techniques.

Before and after orthodontic treatment: This transformation highlights how comprehensive orthodontic care can improve tooth alignment, spacing, and overall smile aesthetics.

1. MARPE Is About More Than Straight Teeth

A narrow upper jaw can affect far more than your smile.

By expanding the upper jaw, MARPE may help:

✔ Create additional space for crowded teeth by widening the upper dental arch and reducing the need for tooth extractions in some cases

✔ Support healthier jaw development by addressing underlying upper jaw width concerns during growth and adulthood

✔ Improve smile balance and facial harmony by creating a broader, more proportional dental arch

✔ Increase palatal width to support proper alignment of the upper teeth and improve arch form

✔ Create a stronger orthodontic foundation by improving the relationship between the upper and lower jaws

✔ Improve bite alignment by helping correct issues related to a narrow upper jaw, such as crossbites

✔ Support better tongue posture and oral function by providing more space within the palate for proper tongue positioning

✔ Enhance airway-focused orthodontic treatment planning by considering how jaw development, breathing, and oral function are connected

✔ Improve long-term orthodontic stability by creating a more balanced foundation for future tooth movement

For many patients, these benefits extend beyond appearance alone.

A smile transformation is about more than appearance. Comprehensive orthodontic care focuses on creating proper alignment, improved function, and a healthy, confident smile designed around each patient’s needs.

2. Your Airway Matters More Than You Think

Here's something many people don't realize...

The roof of your mouth is also the floor of your nose.

When the upper jaw is narrow, the nasal passages may also be narrower.

That's one reason patients seeking MARPE often experience:

• Mouth breathing

• Snoring

• Poor-quality sleep

• Narrow dental arches

• Dental crowding

  
  

While every patient is different, evaluating the airway has become an important part of comprehensive orthodontic care.

3. MARPE Has Changed

One of the biggest misconceptions about MARPE?

People expect a large gap between their front teeth.

Modern treatment has evolved.

Instead of rapid expansion, many orthodontists now use slower activation protocols that often provide:

✔ Greater comfort

✔ More controlled expansion

✔ Minimal spacing between the front teeth

✔ Predictable treatment progress

Patients are often surprised by how manageable treatment feels.

A smile transformation begins with understanding each patient’s unique needs. Orthodontic treatment can help create improved alignment, balance, and function.

4. Every Appliance Is Custom Made

There is no "one-size-fits-all" MARPE.

Before treatment begins, we create a personalized plan using:

• 3D CBCT imaging

• Digital intraoral scans

• Clinical photographs

  
  

These records allow us to design a custom appliance and accurately position the TADs (mini-implants) for optimal comfort and precision.

5. Adults Can Get MARPE Too

Many people assume jaw expansion only works in children.

That's no longer the case.

Because MARPE works at the skeletal level, it can be an effective option for many children, teens and adults, depending on their anatomy and treatment goals.

After placement, mild soreness is normal for a few days.

We'll monitor your progress with scheduled follow-up visits and imaging, guide you through activation, and leave the appliance in place for several months after expansion to allow the new bone to stabilize.

Our goal is to make treatment safe, comfortable, and predictable every step of the way.

From crowded teeth to a more confident smile — personalized orthodontic treatment helps patients achieve a smile that looks and feels better.

Is MARPE Right for You?

You may benefit from a MARPE consultation if you experience:

• Frequent mouth breathing

• Snoring or restless sleep

• Crowded teeth

• A narrow upper jaw

• Airway concerns

• Interest in non-extraction orthodontic treatment

At Westwood & Starwood Dental, we combine 3D imaging, advanced digital technology, and an airway-focused approach to create personalized treatment plans for teens and adults.

Every smile is unique. Through personalized orthodontic care, patients can achieve improved alignment, balanced function, and a smile that supports their overall oral health.

Frequently Asked Questions

What is MARPE in orthodontics?

MARPE (Mini-Screw Assisted Rapid Palatal Expansion) is an orthodontic treatment that uses small mini-screws placed in the palate to gently widen the upper jaw. It can help improve jaw width, create space for teeth, and support better oral function.

How does MARPE work?

MARPE uses a custom expander supported by mini-screws to apply gentle pressure to the upper jaw. This helps encourage skeletal expansion rather than relying only on tooth movement.

Is MARPE different from a traditional palate expander?

Yes. Traditional expanders are mainly supported by the teeth, while MARPE uses mini-screws to help target expansion of the upper jawbone. This makes it a potential option for older teens and adults.

Can adults get MARPE?

Yes. MARPE can be an effective treatment option for many adults with a narrow upper jaw, crowding, crossbite, or airway-related concerns. A consultation is needed to determine if MARPE is right for you.

Does MARPE hurt?

Most patients experience mild pressure, tightness, or soreness for a few days after placement and during expansion. Our team provides guidance to help make treatment as comfortable as possible.

How long does MARPE treatment take?

Active expansion typically takes several weeks. After expansion is complete, the appliance remains in place for a retention period to allow the new bone to stabilize.

Does MARPE create a gap between the front teeth?

Some patients may notice temporary spacing between the front teeth during expansion. With slower expansion protocols, this spacing is often minimal and varies from patient to patient.

Can MARPE help with breathing or airway health?

By widening the upper jaw, MARPE may increase nasal airway space and support improved breathing patterns in some patients. It is one component of a comprehensive airway-focused approach.

Who is a good candidate for MARPE?

MARPE may benefit patients with a narrow upper jaw, dental crowding, crossbite, or reduced palatal width. A detailed evaluation, including digital imaging, helps determine candidacy.

Is MARPE treatment safe?

When properly planned and monitored by an experienced dental team, MARPE is considered a safe orthodontic treatment option for appropriately selected patients.

Can MARPE be combined with Invisalign® or braces?

Yes. MARPE is often combined with orthodontic treatments such as Invisalign® or braces to help create a stable, functional, and balanced smile.

How do I know if MARPE is right for me?

A consultation with Westwood & Starwood Dental can help determine whether MARPE is the right solution based on your smile, bite, jaw development, and airway health goals.
