How Your Child’s Tongue Shapes Their Face — and Their Future Airway
What every parent should know about orthodontic expansion, airway health, and proper tongue posture
If your child is snoring, mouth breathing, grinding their teeth at night, or already being evaluated for braces — this post is for you.
As a parent, you may not have been told that your child’s tongue plays a huge role in how their jaw develops, how well they breathe, and whether their orthodontic treatment will actually last.
Let’s break it all down — so you can make the most informed decisions for your child’s health.
👅 The Tongue: Nature’s Orthodontic Expander
When your child’s tongue is resting at the roof of their mouth (where it should be!), it acts like a natural palate expander. It applies gentle, consistent pressure that encourages the upper jaw to grow wide and forward — which supports:
Proper nasal breathing
A wider, healthier airway
Space for all their permanent teeth
Better facial symmetry
Lower risk of orthodontic relapse
🧠 Think of it like this: the tongue is meant to be the “scaffolding” that helps build your child’s midface and airway. But if it’s hanging low, resting on the floor of the mouth, or not moving properly due to a tongue tie, the jaw may develop too narrow — leaving little room to breathe or grow.
👃 Narrow Jaws = Narrow Airways
Children with narrow palates and underdeveloped jaws often present with the following signs:
Snoring or noisy breathing at night
Teeth grinding
Chronic mouth breathing
Allergies or “stuffy nose” appearance
Forward head posture
Crowded teeth or crossbites
Dark circles under the eyes (“allergic shiners”)
Behavioral signs like poor focus or restlessness
These aren’t just cosmetic concerns — they’re often signs of airway restriction, which can impact sleep, growth, attention, and even mood.
And that’s why airway-focused orthodontic expansion — combined with myofunctional therapy — is one of the most powerful things you can do to support your child’s development.
🦷 What is Orthodontic Expansion — and How Can It Help?
Orthodontic expansion uses a device (like a palate expander) to widen the upper jaw. This creates more room for teeth and — most importantly — improves space in the nasal and oral airway.
But here’s the catch: expansion alone isn’t always enough. If the tongue continues to rest low or the child is still mouth breathing, the jaw may collapse again over time… leading to orthodontic relapse and continued breathing problems.
That’s where myofunctional therapy comes in.
💪 Myofunctional Therapy: The Missing Link in Lasting Expansion
As a dental hygienist and certified myofunctional therapist, I help children:
Learn proper tongue posture (resting on the palate)
Develop nasal breathing habits
Strengthen the muscles that support jaw growth
Retrain oral habits like thumb sucking or open-mouth rest
Prepare for or recover from a tongue tie release (if needed)
When done in tandem with orthodontic expansion, myofunctional therapy ensures your child’s facial structure is supported by proper function — not just hardware.
This is about more than straight teeth. This is about helping your child breathe, sleep, and thrive.
💬 Real Talk from a “Dental Doula”
You might be thinking:
“But my child’s teeth look fine…”
“They’re just a mouth breather because they’re stuffy all the time…”
I hear this every day — and it’s completely normal to not know what to look for. That’s why I offer gentle evaluations and education for families.
My role isn’t just to provide exercises — it’s to guide you through the entire process with care, clarity, and collaboration. I often work closely with your child’s orthodontist, ENT, or pediatric dentist to create the most effective care plan possible.
🔍 Signs Your Child May Benefit From a Consultation:
Snoring or teeth grinding
Mouth always open, even at rest
Crowded baby or adult teeth
History of tongue tie or tight upper lip
Frequent congestion or allergies
Difficulty keeping lips closed
Tongue sticking out between the teeth
Diagnosed with sleep-disordered breathing or OSA
If your child checks more than one of these boxes — now is the time to schedule a consultation.
✅ Take the First Step
🌟 The earlier we address airway and jaw development, the better. Myofunctional therapy works best before or during orthodontic expansion, and the results can be life-changing.
