Key Takeaway: Myofunctional therapy retrains the muscles of the tongue, lips, and face through targeted exercises. When these muscles don’t function correctly, pediatric dentists call it an orofacial myofunctional disorder (OMD). OMDs show up as mouth breathing, tongue thrusting, and improper swallowing patterns, and over time they can affect jaw development, the position of teeth,, and how well a child sleeps. A pediatric dentist is often the first clinician to spot the signs during a routine exam. Most children aged four and older can participate in myofunctional therapy, with many families noticing real improvement within six to twelve months. At Little Pearls Pediatric Dentistry in North York, Toronto, a certified myofunctional therapist works with the practice’s pediatric dentists to catch and correct these patterns before they create bigger orthodontic or airway issues down the road.
Your child’s tongue is doing a lot more than tasting food. Where it rests, how it moves when swallowing, whether your child breathes through their nose or mouth: all of that shapes jaw growth, tooth alignment, and sleep. Most parents haven’t heard of myofunctional therapy until a dentist brings it up.
What Does “Myofunctional” Mean?
“Myo” means muscle. So myofunctional therapy is really just physical therapy for the mouth and face. The tongue, lips, cheeks, jaw: these are all muscles, and like any muscles, they can develop bad habits.
Clinically, the term is orofacial myofunctional disorder, or OMD. What does that look like in a kid? Maybe the tongue pushes forward against the front teeth every time they swallow (dentists call this tongue thrusting). Maybe they breathe through their mouth all day because their tongue sits low on the floor of the mouth instead of up against the palate where it belongs. These aren’t random quirks. Left alone, they can change the shape of a child’s face and the way their airway develops.
How Would I Know If My Child Needs It?
You probably wouldn’t, on your own. A pediatric dentist is often the first person to pick up on the signs because we’re already watching for them during a routine recall exam. We check teeth and bite, yes, but we’re also paying attention to how your child breathes, where their tongue sits, whether their lips close naturally.
Mouth breathers develop a recognizable look over time. The face gets longer. The upper jaw stays narrow. Dark circles show up under the eyes, and parents often assume it’s allergies. Open-mouth posture also dries out the mouth, which can increase risk of cavities and gingivitis.
Then there’s tongue thrusting. Every time your child swallows, the tongue pushes forward against the front teeth instead of pressing up against the palate. That happens thousands of times a day. Over months and years, it can open up a gap between the top and bottom front teeth or flare the upper ones forward. Snoring, teeth grinding at night, and trouble with certain speech sounds can all tie back to these muscle patterns too.
What Does Myofunctional Therapy Actually Involve?
No devices. No appliances, usually. It’s exercise-based. Think of it as teaching the tongue where to live and how to move correctly.
A typical programme has a few components: tongue strengthening exercises so it can hold position against the roof of the mouth, lip seal work to get your child breathing through their nose instead of their mouth, and swallowing retraining. That last one is the big one. The tongue needs to learn to press up and back when swallowing, not forward into the teeth.
Kids practise these at home for a few minutes a day. They’re not complicated, but they require consistency, and that’s where families hit a wall. The therapy works best when parents stay involved and when the child is old enough to self-correct. The American Speech-Language-Hearing Association notes that kids under four often can’t self-monitor well enough for the exercises to stick. We’ve found the same at Little Pearls. Four and up is the sweet spot, though some younger kids manage simpler versions.
Why Does a Pediatric Dentist Care About Tongue Posture?
Form follows function. That phrase gets thrown around a lot, but in a kid’s mouth it’s literally true.
The tongue is supposed to rest against the palate all day long. That constant, gentle pressure acts like a natural expander, widening the upper jaw as the child grows. Take that pressure away and the jaw stays narrow. Narrow jaw, crowded teeth, smaller nasal airway. It all connects.
This is also why myofunctional therapy keeps coming up in conversations about tongue and lip ties. If a tight frenulum is physically tethering the tongue down, it can’t reach the palate no matter how many exercises a child does. Sometimes a tongue tie release is needed in combination with myofunctional therapy. If this is the case, we recommend therapy both before and after: before, to strengthen the muscles, and after, to train the tongue into its new range of motion.
The AAPD now includes airway assessment and screening for orofacial myofunctional disorders in its clinical guidance for monitoring children’s growth. Ten years ago, that wasn’t on most pediatric dentists’ radar. It is now.
Can It Actually Improve My Child’s Sleep?
More kids than you’d expect have some form of sleep-disordered breathing. If your child snores, sleeps restlessly, breathes through their mouth at night, or still wets the bed past the expected age, those can all be connected.
Peer-reviewed research supports the idea that myofunctional therapy can reduce sleep-disordered breathing in children by improving muscle tone in the tongue and throat. That doesn’t replace a sleep medicine evaluation for a child with suspected obstructive sleep apnea. But as one piece of a bigger picture, training these muscles can change how well a child breathes overnight. And a child who breathes better sleeps better, focuses better at school, and is generally easier to live with in the morning.
Who Provides Myofunctional Therapy at Little Pearls?
Our dental hygienist Drashti. She completed dental school before moving to Canada, earned her Dental Hygiene credentials, and then went on to get her Myofunctional Therapy certification on top of that. Myofunctional therapy at Little Pearls is her area, and she coordinates directly with our pediatric dentists on every treatment plan.
How long does it take? That depends on the child. Families who stay consistent with the home exercises typically see real progress within six to twelve months.
What If My Child Already Has Braces?
It actually complements orthodontic treatment. Here’s the issue: if your child’s tongue keeps pushing forward against the teeth after braces come off, those teeth are more likely to shift back. Training proper tongue posture and swallowing habits while the braces are still on, or right after, helps lock in the results.
Noticed your child mouth breathing, snoring, or pushing their tongue forward when they swallow? Worth mentioning at your next visit with a dentist for children Toronto families trust.
