A simple deep dive into pediatric airway issues
By Dr. Jared Helfant
If you’ve ever looked over at your child sleeping and noticed their mouth hanging open, you’re not the only parent who has wondered if that’s normal. Mouth breathing once in a while (like during a cold) is common. But when it becomes the default—especially with snoring or restless sleep—it can be a sign your child’s airway isn’t working as smoothly as it should.
When people talk about “airway issues” in kids, they usually mean sleep-disordered breathing. The tricky part is that children don’t always look “sleepy” when they aren’t sleeping well. Instead, they can seem extra active, emotional, moody, or easily distracted. That’s one reason airway problems can hide in plain sight.
Where airway problems come from
Airway problems can come from a few places. Sometimes the nose stays blocked from allergies or chronic congestion. Sometimes enlarged tonsils and adenoids take up space and make breathing harder at night. And sometimes it’s related to growth and development—like a narrow upper jaw (palate), crowded teeth, or a tongue that rests low instead of up on the palate. When the tongue sits low and the lips stay open, mouth breathing becomes easier than nasal breathing, and that pattern can become a habit.
The signs parents notice first
Most parents notice the first clues at night. Common signs are snoring, grinding of their teeth, sweating in sleep, or moving around constantly like they can’t get comfortable. Some wake up often, have nightmares, or wet the bed longer than expected. If you ever see breathing pauses followed by a gasp, that’s a strong reason to get evaluated. Other signs to look out for are waking up with dry lips, dry mouth, or bad breath even when they brush well.
Many kids will act tired, which might look like irritability, low patience, big emotional reactions, or trouble focusing at school. It doesn’t mean every child with behavior or attention issues has an airway problem, but when sleep signs and daytime struggles show up together, it’s worth paying attention.
Why mouth breathing matters
So why does mouth breathing matter? First, it can affect sleep quality. Broken sleep can affect mood, learning, memory, and attention. Second, mouth breathing can influence facial and jaw development. Kids are still growing, and the body adapts to posture. When the mouth stays open and the tongue stays low, the upper jaw may not develop as wide as it should. That can lead to crowding, a narrow palate, and less room for the tongue—making mouth breathing even more likely. Finally, dry mouth matters for dental health: less saliva overnight can increase cavity risk and gum irritation.
What a good evaluation looks like
A good airway-focused evaluation usually looks beyond “just teeth” or “just tonsils.” Providers review sleep habits, snoring, and daytime behavior. They check nasal breathing, tongue posture, and jaw development. In some cases, a sleep study is recommended, and an ENT evaluation can be important when tonsils/adenoids or nasal obstruction are suspected.
Treatment is a combination, not one magic fix
Treatment is usually a combination, not one magic fix. Myofunctional therapy is often part of the plan—it’s like physical therapy for the mouth and face, helping a child learn nasal breathing, lips closed at rest, tongue up on the palate, and a healthier swallow pattern. Some children benefit from a tongue-tie release (frenectomy), but the main question is function: is the tongue truly restricted from lifting and resting comfortably on the palate? When it is, release plus therapy can help. Palatal expansion is another major tool when the upper jaw is narrow, creating more room for the tongue and supporting better nasal airflow during growth.
Many kids can also benefit from an airway-focused starter appliance like the Vivos vStarter, often called a “tooth pillow.” It’s designed to be gentle and kid-friendly, and the goal isn’t perfect teeth overnight. The goal is to support healthier growth patterns while your child is still developing. It can help encourage a natural lip seal and guide the tongue to rest on the palate instead of sitting low—two basics that often make nasal breathing and calmer sleep easier.
The takeaway is simple: if your child snores often, mouth breathes most nights, or has restless sleep with daytime behavior changes, don’t assume they’ll “just grow out of it.” Getting an airway-focused evaluation early can make a big difference.
