How Toothpillow is helping parents catch jaw issues before they come bigger problems
Table of Contents
You’ve probably been told not to worry. That the snoring is normal. That the open mouth during sleep is “just how some kids breathe.” That the crowded teeth will sort themselves out eventually. But something in your gut keeps nudging you—and it turns out, that instinct might be worth listening to.
A growing body of research is revealing that the way your child breathes—especially during sleep—plays a significant role in how their jaw, face, and airway develop. And for many families, catching the signs early and seeking the right kind of support is making a meaningful difference.
Why breathing matters more than you might think
Here’s something that surprised us: approximately 60% of a child’s facial growth is complete by age 4, and 90% by age 12. That means the window for supporting healthy development is narrower than most parents realize—and the way a child breathes during those critical years can literally shape their face.
A systematic review published in BMC Oral Health found that children who breathe primarily through their mouths tend to develop longer, narrower faces, steeper jaw angles, and crowded teeth. The reason comes down to tongue position: when a child breathes through their nose, the tongue rests against the palate, providing gentle pressure that helps the upper jaw develop properly. When they mouth-breathe, the tongue drops, and that natural support disappears.
Research published in Frontiers in Public Health echoes these findings, noting that mouth breathing during critical growth periods can lead to a narrower palate, misaligned bite, and—perhaps most importantly—a smaller airway. In other words, the way your child breathes today can affect how well they breathe for the rest of their life.
Signs that something deeper might be going on
If you’re a parent who has noticed any of the following in your child, you’re not imagining things—and you’re not overreacting. These are some of the signs that pediatric airway specialists say are worth investigating:
- Mouth breathing during the day or while sleeping
- Snoring, restless sleep, or pauses in breathing at night
- Crowded or crooked teeth coming in
- Dark circles under the eyes or chronic congestion
- Difficulty focusing, hyperactivity, or mood swings (sometimes misattributed to behavioral issues)
- Bedwetting beyond the expected age
- A narrow or elongated facial shape
According to the American Academy of Pediatrics, sleep-disordered breathing affects an estimated 1–6% of children, though many experts believe the true prevalence is higher because the symptoms are so often attributed to other causes. As Motherly has previously explored in our guide to pediatric sleep apnea, children with obstructive sleep apnea often present with behavioral symptoms—hyperactivity, impulsivity, difficulty regulating mood—that can look a lot like other conditions.
A new approach: catching it early, from home
This is where things get empowering. A growing number of families are discovering that you don’t have to wait until your child’s permanent teeth are in—or until a problem becomes severe—to take action.
Toothpillow is a virtual, doctor-guided program designed to evaluate and support children’s jaw growth, breathing, and facial development—all starting from home. Founded by Dr. Ben Miraglia, the program pairs every family with a licensed airway dentist who reviews uploaded photos and health history to assess whether a child’s development is on track.
What makes the program stand out is its accessibility. The process starts with a free virtual assessment—parents answer a few questions, snap some photos, and receive a personalized evaluation without ever leaving the house. If the dentist identifies areas of concern, families receive a customized treatment plan that may include guidance appliance therapy (a device worn at night and briefly during the day to encourage proper tongue positioning and jaw alignment) and myofunctional therapy (targeted exercises that strengthen the muscles involved in breathing, swallowing, and jaw movement).
The science behind the approach
If the concept of “mouth exercises” sounds unfamiliar, the research may reassure you. Myofunctional therapy has been gaining significant attention in the pediatric dental and sleep medicine world. A 2024 review in pediatric dentistry literature highlighted its role in addressing sleep-disordered breathing and supporting healthy craniofacial development in children. Multiple peer-reviewed studies have found that these interventions can improve airway function, reduce snoring, and support better sleep quality—all of which contribute to a child’s overall growth and wellbeing.
A systematic review published in MDPI Children examining the effects of orofacial myofunctional therapy on children with obstructive sleep apnea found promising results for craniofacial growth and airway improvement. And a 2025 network meta-analysis further supported myofunctional therapy as a beneficial approach, particularly when combined with consistent daily practice.
The idea behind programs like Toothpillow is that by guiding jaw growth and encouraging proper muscle function early—while the face is still developing—you can create the space teeth need to come in naturally, potentially reduce the need for braces later, and support healthier breathing patterns that affect everything from sleep to focus to mood.
What the program actually looks like for families
One of the things we appreciate about Toothpillow’s model is that it’s designed to fit into real family life. After the initial assessment, families who are approved for treatment receive their guidance appliance at home. Children wear it each night during sleep and for one to two hours during the day—often while doing homework or watching a show.
The myofunctional therapy exercises are quick daily routines that most kids can do independently after a bit of practice. Think of them as a workout for the muscles that help your child breathe, swallow, and hold their jaw in the right position. Virtual check-ins with the care team keep everything on track without constant trips to a clinic.
With consistent daily use, families typically begin to see visible changes in teeth and bite within three to six months, with improvements in breathing and sleep quality starting around six to nine months. The suggested treatment duration is about two years.
You know your child best
Here’s the thing we keep coming back to at Motherly: nobody knows your child the way you do. If their sleep has never quite felt right, if their breathing worries you, if you’ve wondered whether those crowded teeth mean something more—those observations matter. The research is clear that early intervention during the years when the face is still growing can make a real difference.
As we’ve shared in our guide to recognizing when your child’s sleep needs a reset, heavy breathing and loud snoring are always worth discussing with your pediatrician. And if you’re looking for a proactive, research-backed approach that meets you where you are—at home, on your schedule—programs like Toothpillow are making that more accessible than ever.
