Palatine expanders: what are they used for and when to use them?

A small device… for big changes!

In orthodontics, some treatments begin with a step that is often unknown… but nevertheless essential: palatal expansion. The device used? The Palatine Expander. Discreet, but frighteningly effective, this small device can transform a smile into a soft one.

At Amortho, we like to make orthodontics more accessible, by simply explaining what happens behind each appliance. So, what is a palatal expander used for? And in what cases is it used?

 

WHAT IS A PALATAL EXPANDER?

The palatal expander is an orthodontic appliance that is installed on the palate, often attached to the molars. His mission? Gradually widen the upper jaw.

It is activated with a small key, according to a precise protocol given by the orthodontist. The movement is very gentle, but as the days go by, it helps create more space in the mouth.

Why use it? To correct a lack of space, prevent or treat crowded teeth, or to improve occlusion (the way the upper and lower teeth fit together). This is often a first step before a more complete treatment with braces or other devices.

Why enlarge the palate?

In some children, the palate is too narrow. As a result, teeth can grow crooked, lack space, or lead to a crossbite (when the upper teeth bite into the inside of the lower ones).

Palatal expansion corrects this imbalance by changing the width of the palate while the bones are still malleable. We therefore often act before adolescence, in a period when development is still very active.

 

At what age do you use a palatal expander?

In general, palatal expansion is recommended between the ages of 7 and 12, before the closure of the bony sutures of the palate. That’s why a first orthodontic appointment is often suggested around the age of 7 — even if no treatment is started right away.

That said, every child is unique! The orthodontist assesses the situation with X-rays, 3D scans and a detailed clinical examination.

Is it painful?

The expansion can cause slight discomfort in the first few days: feeling of pressure in the nose, palate or between the teeth. But it’s the feeling is usually painless and quick to fade.

After a few activations, the device quickly becomes a daily companion, and young patients adapt to it very well. Promised!

 

And after the expansion?

Once the desired enlargement has been achieved, the device often remains in place for a few months to stabilize the results. Afterwards, the orthodontist will be able to plan the rest of the treatment (braces, aligners, etc.) with a well-prepared jaw.

It’s a bit like creating the foundation before building the house: a solid foundation allows for a more stable result… and a lasting smile!

Halloween 2025 at Archambault Morton

Halloween 2025 Halloween like no other at the clinic! 🐾 This year, the Archambault & Morton team has transformed itself into a team of... pack of Dalmatians! 🐶 That's right, for Halloween, we've put on our best costumes inspired by the movie 101 Dalmatians – and...

Living with braces: what you are not told (but that you will quickly understand)

Living with braces: what you are not told (but that you will quickly understand)

Living with braces: what you are not told (but that you will quickly understand)

Starting orthodontic treatment is a bit like starting a new relationship: you have to tame yourself, adapt, and accept a few small discomforts for a big better future.

Whether you wear classic braces, transparent braces or invisible aligners, one thing is certain: your everyday life will change… but not always in the way you imagine.

Here is a realistic, but reassuring, overview of what you will experience once the device is installed.

The first few days: welcome to your new mouth

Let’s be honest: the first few days can be a little confusing.

What you might feel:

  • Tension in the teeth (it moves, it’s normal)

  • A slight pain when biting (until it stabilizes)

  • Temporary lisping (especially with the gutters)

  • Small irritations on the tongue or cheeks (long live orthodontic wax!)

Tip : Eat soft foods (purees, compote, smoothies) for 2-3 days. And keep paracetamol on hand if needed.

The good news is that the body adapts quickly. After a week, most patients find their rhythm.

Eating with a Device: The Art of Reinventing Your Meals

It’s not that you can’t eat anything anymore. But you have to learn to eat differently.

To avoid (or adapt):

  • Bite into a whole apple: prefer slices

  • Popcorn, caramels, nuts: too risky

  • Sandwiches that are too crusty: cut, chew gently

Your new allies:

  • Rice, pasta, banana, cooked vegetables and more…

  • A pocket toothbrush (essential after each meal)

  • Containers for your gutters if you remove them

Interestingly, many patients are rediscovering a healthier diet (less snacking, more food awareness).

Talking, laughing, socialising: should we be ashamed of our brooches?

Absolutely not. But it takes a little time to adapt.

With visible pins :

  • You can feel observed… at first.

  • But a lot of people find it cool or “brave”.

  • Self-mockery is a powerful weapon: “Yes, I’m in a construction site version, but it’s temporary!”

With invisible aligners :

  • Almost no one notices.

  • Be careful, however, to articulate well for a few days.

“I made my first customer pitch with my aligners. No one noticed anything. It’s more in the head than anything else.”

Oral hygiene: we go up a level

With a device, the hygiene routine becomes non-negotiable :

  • Brush after each meal (at least morning and evening)

  • Use interdental brushes or a dental spray

  • Avoid sugary sodas or juices that are too acidic

Pro tip: Keep a hygiene kit in your bag, car, or desk drawer.

Yes, it requires a little more discipline. But after a few weeks, it becomes automatic and your teeth will thank you!!

In short: it’s a small “sacrifice” for a big change

Living with braces is not always comfortable. There are adjustments, small pains, moments when you doubt.

But it’s a parenthesis in your life… for a smile that will last a lifetime.

What we don’t tell you enough: the pride that comes with it

There’s something rewarding about seeing your teeth move. Every visit to the orthodontist, every before/after photo, every remark from a loved one becomes a motivation boost.

“It’s crazy how your smile has changed.”

“You did this for yourself, and it shows.”

Orthodontic treatment is also a process of self-care. And as the months go by, confidence grows.

And then? The stabilization phase (and the small fear of relapse)

Once the appliance is removed, it’s time for the restraint (night aligners, glued retention wire, etc.). This step is essential to maintain results.

A word of advice : don’t skip this phase. Otherwise, the teeth can move again, and everything would have to start over.

Orthodontics, sleep and posture

Orthodontics, sleep and posture

Orthodontics, sleep and posture

Orthodontics is often thought to be reserved for the aesthetic alignment of the teeth. But what few people know is that poor jaw positioning can disrupt much more than just your smile.

Unexplained neck pain? Short breathing during the day? Declining sports performance? Non-restorative sleep despite 8 hours in bed?

What if it all started… in your mouth?

Breathing and jawline: an inseparable duo

We don’t talk about it enough, but chronic mouth breathing can have dramatic consequences:

  • less oxygen absorbed,

  • increased fatigue,

  • chronic inflammation,

  • and in children, attention or developmental disorders.

When the dental arches are too narrow, the air circulates poorly, the tongue rests in a low position, and the nose becomes underused. This imbalance can travel up to the cervical muscles and cause a postural hypercompensation.

Orthodontic appliances such as palatal expanders or functional aligners can improve this situation within a few months.

Orthodontics and sleep: the war against apnea

Sleep apnea is not just a snoring problem. It reduces quality of life, increases cardiovascular risks… and also affects young, slim and athletic people.

Some apneas are caused by:

  • a receding jaw,

  • a narrow palace,

  • a tongue that is too low during sleep.

Orthodontists trained in dentofacial orthopedics can prescribe advanced appliances that reposition the jaw or widen the palate, radically improving sleep quality.

And yes, sleeping better also means thinking better, performing better, and living better.

And for athletes? A smile that boosts performance

High-level athletes are now integrating orthodontics into their performance strategy. What for? Because a misalignment of the jaw:

  • unbalances the neck and back,

  • reduces respiratory quality during exercise,

  • Disrupts concentration and proprioception.

Recent studies have shown that better oral-maxillary alignment can:

  • a more stable posture,

  • Improved recovery,

  • and increased coordination.

Even disciplines like yoga or running can benefit from these adjustments.

Functional orthodontics: a comprehensive and preventive approach

More and more practitioners are taking a holistic approach to orthodontics, in collaboration with:

  • physiotherapists,

  • posturologists,

  • osteopaths,

  • or even sports coaches.

The goal: to rebalance the body at the source, not just straighten the teeth.

In children, this approach can prevent chronic disorders in adulthood. In adults, it can release tension that has been building up for years.

Remember: Your teeth influence much more than your smile

Too often, we think that orthodontics is “just” a question of straight teeth. But in reality, Your mouth is a postural, respiratory, and muscular command center.

An orthodontic check-up, even in adulthood, can reveal subtle but crucial imbalances. And in many cases, an appropriate treatment allows:

  • better posture,

  • more fluid breathing,

  • restful sleep,

  • and a real feeling of global alignment… from head to toe.

What if your performance, posture, and energy depended on what you don’t see in the mirror?

Maybe it’s time to see a doctor, not for your teeth… but for everything they influence.

INTERNSHIP IN ORTHODONTICS: an enriching immersion at ARCHAMBAULT & MORTON ORTHODONTISTES

The next generation is curious, passionate… and full of promise!
On the occasion of their end-of-year observation internship, five high school students came to experience an Orthodontic Internship Day at our Archambault & Morton clinic in Vaudreuil. A moment rich in discoveries, learning… and smiles!

A first day of orthodontic internship

Alana, Emma, Sophie, Amélie and Alissa were welcomed by our team for a full day exploring the different essential roles of an orthodontic clinic. From the laboratory to the sterilization room, including reception, assistance and the installation of elastic bands on training dentures with braces, our trainees were able to see how each gesture contributes to creating healthy smiles.

Concrete gestures, real learning in orthodontics

Supervised by our passionate professionals, the interns have:

  • Performed orthodontic elastics on dental models,

  • observed the sterilization methods in our workshop with Karen,

  • visited each station of the clinic to better understand the role of each worker.

A great way to demystify the profession of orthodontist, hygienist and dental assistant, while allowing young people to explore their professional future.

National Dental Hygienists Week: Keep Your Smile Healthy!

Research has shown that conditions like gingivitis and periodontitis can promote the circulation of bacteria in the blood, increasing the risk of heart disease, stroke, and diabetes-related complications. The mouth is a true gateway to the body. Taking care of your teeth also means taking care of your heart, lungs, and immune system.

Why oral health is essential to overall health.

Every April, National Dental Hygienists Week (April 4-10 in 2025) is the perfect opportunity to recognize the fundamental role dental hygienists play in promoting oral health. Whether in clinics, schools, or with vulnerable populations, these professionals are quiet but powerful pillars of our healthcare system. Their mission goes far beyond cleaning teeth: they educate, prevent, and actively contribute to our overall well-being—one smile at a time.

Let’s demystify Orthodontics for Adults…

Orthodontics is no longer just for young people. According to recent studies, one in five orthodontic patients is an adult. This increase is partly due to technological innovations such as discreet braces like Invisalign, which offer an aesthetically pleasing alternative to traditional metal braces. These less visible options make adults more comfortable with the idea of starting orthodontic treatment at an older age.

Additionally, advances in orthodontics have also improved the effectiveness of treatments, allowing for faster and less painful adjustments than in the past. Today’s adults therefore have tailor-made solutions that respect both their aesthetics and their busy schedules, making orthodontic treatment not only acceptable but desirable at any age.

Dental hygienists: pillars of our health system

With over 34,000 hygienists licensed to provide care in nearly every Canadian province without direct supervision, these professionals play a key role in preventing oral disease. They are also often the first to detect signs of general illness and actively contribute to access to healthcare.

Caring for the elderly and children: an intergenerational issue

Seniors are at greater risk of cavities, dry mouth, and tooth loss. Appropriate techniques exist to provide them with comfort and dignity. For children, sealants and early screening can prevent future complications. Investing in their oral health means giving them a healthier future.

A beautiful smile changes everything: why your teeth influence your health, your happiness… and your trust!

A beautiful smile changes everything: why your teeth influence your health, your happiness… and your trust!

A beautiful smile changes everything: why your teeth influence your health, your happiness… and your trust!

The powerful link between teeth, health and happiness

We often underestimate the impact of our oral health on our overall well-being. However, several studies confirm it: poorly maintained teeth can affect the heart, joints, digestion… and even self-esteem.

A beautiful smile is a virtuous circle. When your teeth are aligned, white and healthy:

  • You tend to smile more often.

  • Your posture naturally improves (yes, confidence changes posture).

  • Others perceive you as more open, credible, and warm.

  • And, unintended consequence: you are perceived as more competent, according to a study published in the Journal of Orthodontics.

In short: good tooth alignment influences the perception you have of yourself… and that which others have of you.

Dental braces: more than a BASIC tool

We all have the classic image of the teenager with metal brooches, avoiding Halloween candy. However, orthodontics has changed a lot. Today, invisible braces and transparent braces make the experience much more pleasant, discreet and… adult.

What are the types of modern braces?

  • Transparent ceramic pins : virtually invisible, but just as effective as metallics.

  • Removable aligners (Invisalign type): perfect for adults, they can be removed to eat and brush their teeth.

  • Lingual braces : placed at the back of the teeth, they are completely invisible from the front.

These alternatives make it possible to correct:

  • teeth that are overlapped or spaced out,

  • malocclusions (misalignment of the jaw)

  • Jaw pain or chronic migraines related to poor positioning.

Pros and Cons: Should You Really Correct Your Smile as an Adult?

Benefits:

  • Aesthetics : the most obvious. But this is only the tip of the iceberg.

  • Health : Proper alignment makes brushing easier, reduces the risk of cavities, tartar, and gum disease.

  • Trust : Many patients report that their social and professional lives changed after their treatment.

  • Prevention : correcting now means avoiding heavier (and more expensive) treatments later.

Disadvantages:

  • Cost : Orthodontic treatments can cost between $3,000 and $8,000 depending on the type of appliance.

  • Duration : it takes 12 to 24 months on average.

  • Discipline : For aligners, they should be worn for at least 20 hours a day for effective results.

But many professionals offer financing plans, and dental insurance sometimes covers a part. Some orthodontists also offer free consultations to evaluate your options.

Psychological impact: what your smile says about you (and how you feel)

A smile is like a personal logo. He speaks of you, even before you have opened your mouth. And when you have a complex about your teeth, you unconsciously learn to hide your smile, to hold back laughing, or to look away from photos.

To deprive yourself of smiling is to deprive yourself of moments.

According to the Harvard School of Public Health, smiling regularly reduces stress, improves mood, and even immunity. However, we smile less when we don’t like our teeth.

Many patients testify to a significant before/after: “I have changed my energy”, “I finally feel like myself”, “I am no longer afraid to speak in public”. Orthodontics, for some, has been a real trigger for personal transformation.

What if you finally dared to smile without holding back?

Correcting your teeth is not just a matter of beauty. It is a decision of health, trust, and sometimes even personal liberation. Thanks to new technology and more accessible options, it’s never been easier to improve your smile without compromising your lifestyle.

If you’re still hesitating, ask yourself: what would my life be like if I smiled unreservedly? What would it change in my posture, my relationships, my energy?

A beautiful smile is not a luxury. It’s a lever. To live better, to look better, to love yourself better.

So, are you ready to reveal your best smile? 🙂
