Myo Munchee:

What is it, and How Does it Help with Mouth Breathing?

A Simple Oral Appliance with Big Benefits

Myo Munchee is a small but powerful oral device designed to improve oral health, jaw development, and breathing patterns — especially in children. If your child (or even you) are experiencing chronic mouth breathing, snoring, or issues with oral habits like thumb sucking, the Myo Munchee might be a helpful tool to support better function and long-term health.

What is a Myo Munchee?

The Myo Munchee is a soft, chewable silicone appliance developed by dentists to promote proper oral function. It looks a bit like a mouthguard, but it's designed specifically to be chewed on.

There are various sizes and types of Munchees for babies, children, and adults — each encouraging natural chewing, tongue posture, and lip closure. It’s used as part of a preventative and therapeutic approach in myofunctional coaching, orthodontics, and early childhood development.

How Myo Munchee Helps with Mouth Breathing

Mouth breathing is often a sign of poor oral habits or underdeveloped facial muscles. It can lead to problems like:

Poor sleep quality
Crooked teeth
Narrow palate
Enlarged tonsils/adenoids
Speech and swallowing issues

Myo Munchee helps combat mouth breathing in several ways:

Encourages Nasal Breathing

By promoting lip closure and correct tongue posture, the Munchee trains the body to breathe through the nose — the way we are naturally meant to breathe.

Strengthens Orofacial Muscles

Chewing on the Munchee helps build strength in the lips, cheeks, and jaw muscles. This makes it easier for children to keep their mouths closed while awake and asleep.

Supports Jaw and Facial Development

Using the Munchee early on can help widen the dental arches, improve facial symmetry, and create space for proper tooth alignment — all of which are linked to better breathing and airway health.

Breaks Harmful Habits

The device can help eliminate thumb sucking, tongue thrusting, and other habits that contribute to poor oral posture and breathing issues.

How is it Used?

Myo Munchee is typically used for a few minutes per day. Under the guidance of a dental, orthodontic, or myofunctional professional, the user chews the Munchee daily — often during routines like screen time, reading, or bath time. It’s non-invasive, easy to use, and often becomes part of a child’s daily wellness routine.

Who Can Benefit from Using a Myo Munchee?

Children with open-mouth posture or chronic mouth breathing
Kids showing signs of sleep-disordered breathing (e.g., snoring, restless sleep)
Toddlers who rely on pacifiers or have oral habits
Adults with mild breathing or TMJ concerns
Anyone undergoing myofunctional coaching

Benefits for Toddlers

Early intervention is key — and the toddler years are the perfect time to introduce Myo Munchee as part of daily oral care. Best when introduced as part of a daily routine (e.g., bath time or reading time). Supervised use is essential at this age.

Supports Facial & Jaw Development:

Chewing encourages proper development of the dental arches and facial muscles.

Promotes Nasal Breathing:

By improving muscle tone and encouraging lip closure, the Munchee helps reduce early mouth breathing habits.

Aids in Weaning from Pacifiers or Bottles:

It offers a healthier alternative to prolonged pacifier use, which can lead to bite and speech issues.

Helps Eliminate Oral Habits:

Useful in managing thumb sucking, tongue thrusting, or open-mouth posture.

Boosts Oral Motor Skills:

Strengthens the lips, tongue, and cheeks — essential for speech and swallowing development.

Benefits for Adolescents

This is a critical time for growth, alignment, and airway development. If mouth breathing, snoring, or misaligned teeth are present, the Munchee can support orthodontic and myofunctional goals. Ideal for use alongside professional care (myofunctional professional or orthodontic).

Improves Oral Posture:

Reinforces correct tongue position, closed lips, and nasal breathing.

Supports Orthodontic Treatment:

Often used in conjunction with braces or expanders to help guide natural development.

Enhances Muscle Tone:

Builds strength in facial muscles that influence bite, facial shape, and airway space.

Addresses Sleep Concerns:

May improve sleep quality and reduce snoring linked to mouth breathing or poor jaw posture.

Encourages Functional Habits:

Helps retrain the body to chew correctly, breathe nasally, and swallow properly.

Benefits for Adults

While the Munchee is often used in children, adults can also benefit — especially those with TMJ issues, poor oral habits, or breathing challenges. Adult use should be guided by a myofunctional professional or dental professional for best results.

Improves Orofacial Tone:

Helps activate underused muscles that support the jaw, lips, and cheeks.

Supports TMJ and Jaw Function:

May reduce strain and discomfort associated with weak jaw muscles or clenching.

Encourages Nasal Breathing:

Trains the mouth to stay closed and reinforces correct tongue posture — essential for healthy breathing during rest.

Aids in Myofunctional Coaching:

Commonly used in programs to correct dysfunctional breathing, swallowing, or speaking patterns.

Boosts Overall Wellness:

Improved oral function is linked to better digestion, sleep, and even posture.
