Mouth breathing in children: how MyoTape can help prevent future problems

Parents may not always notice it right away, but the early habit of mouth breathing can shape much more than a child’s smile. How a child breathes—through nose or mouth—affects their facial structure, dental health, sleep, and even how well they pay attention in classrooms. While nose breathing feels instinctive for most, research shows a rising number of children are defaulting to open-mouth breathing patterns. Tackling this issue early helps lay the groundwork for healthier lives well into adulthood.

Mouth breathing is more than just an innocent quirk. Parents often see signs like dry lips, loud nighttime breathing, or restless sleep and brush them aside. Yet these are all clues, pointing to underlying challenges that, left unaddressed, can escalate into medical and developmental problems. Understanding why mouth breathing occurs, what it can lead to, and what interventions are available is the first step toward making informed, proactive choices.

The hidden impacts of mouth breathing

Mouth breathing alters the natural mechanics of the face and airway. Our faces are built to breathe comfortably through the nose, which filters, warms, and humidifies air. Persistent mouth breathing, even years before adult teeth appear, can change how a child’s face grows. This isn’t just cosmetic—changes in the jaws and palate affect how teeth align, and a poorly developed airway can contribute to lifelong sleep issues.

Here are several impacts of mouth breathing on a child’s development:

• Dental alignment problems: The tongue rests best on the roof of the mouth, supporting the shape of the palate. Mouth breathing moves the tongue out of position, leading to narrow dental arches, crowded teeth, and cross-bite.
• Facial structure changes: Chronic mouth breathers may develop longer faces, high palates, or even retruded chins because the muscles around the mouth work overtime holding the jaw open.
• Interrupted sleep and behaviour: Open-mouth breathing at night can result in lighter, fragmented sleep. This leaves children tired, moody, or struggling to focus.
• Speech difficulties: Children who mouth breathe often display speech problems, like unclear pronunciation or lisp.

A simple comparison highlights the broad impact:

Why children start mouth breathing in the first place

Mouth breathing may develop for a variety of reasons, and often, it’s a combination rather than a single cause:

• Nasal congestion: Allergies, enlarged adenoids or tonsils, or frequent colds may leave noses blocked, forcing a child to open their mouth to breathe.
• Habit formation: If nasal congestion persists, the child’s brain develops new breathing patterns that stick—even after the original issue has resolved.
• Physical developments: In some cases, structural differences in the nose or airway make mouth breathing easier than the nasal route.

Many parents might feel powerless about their child’s breathing habits, especially when the root cause isn’t immediately obvious. Fortunately, early observation, gentle reminders, seeking medical opinions, and specific interventions targeted at restoring nasal breathing can bring significant improvements.

The ripple effects: beyond teeth and jaws

Most initially worry about the visual aspects—crooked teeth or altered jaw shape. Yet the effects go deeper.

Children who breathe through their mouths are more likely to experience sleep-disordered breathing such as obstructive sleep apnea. Poor quality sleep can show up as hyperactivity, learning difficulties, or mood swings. Asthmatics or allergy sufferers may notice their symptoms flare up with regular mouth breathing. Constantly open mouths dry out teeth and gums, raising the risk of cavities and gum disease.

There are social impacts, too. A child who wakes up tired or struggles to communicate clearly can miss out on vital developmental experiences.

Recognising the signs early

Spotting mouth breathing patterns before permanent habits set in gives families the best chance of preventing issues. Watch for:

• An open mouth posture while at rest or during sleep
• Snoring or noisy nighttime breathing
• Dry, cracked lips
• Chronic bad breath
• Frequent waking during the night
• Speech or lisping issues
• Crowded or misaligned teeth, even before adult teeth arrive

Take note of these signs and consult with a healthcare provider or paediatric dentist if you notice several occurring consistently.

Intervening early: what works

As with many childhood habits, early intervention matters most. Children respond well to gentle, consistent reminders. Encouraging nose blowing for clear sinuses, allergy treatments, or consulting an ear, nose, and throat (ENT) specialist for anatomical concerns all play a role.

Yet, one innovation is gaining attention among dentists, orthodontists, and airway-focused health professionals: MyoTape.

Understanding MyoTape: a new tool in children’s airway health

MyoTape, developed with children in mind, gently surrounds the lips without obstructing them. Unlike standard mouth tape (often discouraged for children), MyoTape supports lips closed, encouraging nasal breathing, while still allowing the mouth to open if needed.

Its soft, elasticated tape sits comfortably on the skin, making it suitable for night-time use and safer than taping directly over the lips. MyoTape provides a tactile cue—reminding children to keep lips together. Over time, this helps retrain the muscles and nervous system to default to nasal breathing, even when the child is asleep.

Here’s how MyoTape stands apart:

MyoTape in practice: what parents are reporting

A growing number of parents are sharing positive experiences when trying MyoTape for their children. Reports commonly mention:

• Easier, quieter sleep with less mouth breathing and snoring
• Fewer awakenings, more refreshed mornings
• Reduced drool and dry mouth on waking
• An easier time during orthodontic treatments, thanks to better tongue posture

Parents especially value the fact that MyoTape doesn’t “force” the mouth closed or create a feeling of panic for the child. Instead, it sets up a gentle, comfortable boundary that encourages new patterns.

The science behind retraining breathing habits

Changing entrenched habits relies on repeat exposure and gentle cues, not force. While mouth breathing might begin as a necessity during a cold, it can turn into a subconscious pattern. MyoTape utilises the child’s innate drive for comfort: over days and weeks of use, the cues provided by the tape lead to improved nasal breathing even without the tape.

When children become comfortable with nose breathing at night, daily life often changes for the better. Teachers may comment on improved attention, energy levels stabilise, and some families even see improvements in allergy symptoms and immune health.

Next steps for concerned families

Reminding children to breathe through the nose is only part of the solution. Tackling underlying causes—be it allergies, enlarged tonsils, or frequent colds—might require professional help. Dental professionals and airway-focused therapists can play an important part, especially if orthodontic issues have already developed.

If you decide to try a support tool like MyoTape, be sure to:

• Introduce the product during quiet, supervised periods before sleep
• Explain its purpose in simple, reassuring language
• Observe your child’s reaction and remove it immediately if they feel distressed or panicked
• Combine its use with other strategies, such as nasal saline sprays or allergy management, where appropriate

Parents who see early positive changes are often motivated to continue with the new routine, especially when feedback comes not only from home, but from teachers and healthcare practitioners too.

Creating an environment that supports healthy breathing

Children rarely adopt habits in isolation. Their bedroom environment, routines, and even the culture at school can influence how they breathe. Simple changes can create favourable conditions for nasal breathing:

• Encourage regular hand-washing and good hygiene to reduce nasal blockages
• Consider air purifiers in bedrooms for children with allergy issues
• Maintain good humidity in sleeping areas
• Lead by example: parents who model nose breathing help reinforce the standard

Being proactive does not require perfection. Early, gentle interventions, supported by informed tools like MyoTape, tip the scales in favour of positive habits that benefit children well into their teenage years and beyond.

The quiet act of keeping lips together at night and letting the nose do its job is one of those subtle changes that can set off a cascade of lifelong health. As awareness grows and smart solutions become more widely available, there’s every reason to be confident that a new generation can grow up breathing—and thriving—just as nature intended.
