The Myo Munchee is a versatile oral device designed for adults, promoting jaw health, enhancing muscle tone, and improving breathing through the natural action of chewing.
Product Summary
Myo Munchee Adult
Myo Munchee Adult: for 14 years and over
The full-size device. Adult oral muscles lose tone the same way any other muscle does, and a few minutes of gentle chewing a day rebuilds the lip, cheek and tongue strength behind nasal breathing, quieter sleep and a more comfortable jaw.
The Science
Why chewing training changes oral health
Most of us underuse the muscles that shape how we breathe, swallow and rest the jaw. Gentle, rhythmic chewing retrains these patterns, strengthening the lips, tongue, cheeks and jaw through simple daily movement.
Stronger oral muscles
Targets lips, cheeks, tongue and jaw at the same time, building the functional tone behind better swallowing, posture and breathing.
Encourages nasal breathing
Closed-lip chewing trains a tongue-up, lips-sealed posture. Over time this repatterns the default from mouth breathing to calm, efficient nasal breathing.
Gum massage and saliva flow
Gentle chewing stimulates gum tissue and promotes natural salivary cleansing, supporting oral hygiene without chemicals.
Reduces grinding and clenching
Builds balanced jaw muscle coordination rather than raw strength, helping ease the tension patterns behind bruxism and TMJ discomfort.
Better sleep quality
Stronger oral muscles during the day mean a more stable airway at night, reducing mouth breathing, snoring intensity and interrupted sleep.
Effortless daily routine
No batteries, no app, no complex setup. Just gentle chewing during a morning routine, a commute or before bed.
Is the Adult the right size?
This listing is the Adult, for 14 years and over. Size is the biggest lever on whether the Munchee works, so start with the age guide and confirm with the inter-canine width.
| Size | Age guide | Inter-canine width |
|---|---|---|
| Mini | 18 months to 4 years | Use age guide |
| Junior | 4 to 8 years | 30 to 35 mm |
| Tween | 8 to 14 years | 33 to 37 mm |
| Adult this size | 14 years and over | 35 to 40 mm |
How to measure: take the straight-line distance between the tips of the two upper canine (pointy) teeth.
Fit check: Adult fits an inter-canine width of 35 to 40 mm. If you measure 35 to 37 mm you sit in the overlap with Tween, so choose Adult if you are over 14.
Who the Adult is for
Mouth breathers
Most common
Trains the lips-closed, tongue-up posture that shifts your default breathing toward the nose, day and night.
Snorers and poor sleepers
Sleep
Strengthens the oral muscles that help keep the airway open at night. Many users notice reduced snoring within weeks.
Grinders and clenchers
TMJ
Builds balanced jaw coordination rather than raw force, easing the tension patterns behind bruxism and TMJ discomfort.
Gum health
Oral hygiene
Stimulates saliva flow and massages gum tissue as part of a simple, non-invasive daily routine.

The Myo Munchee is one of the simplest tools I recommend to my patients. Whether it is a child who needs to build better oral habits or an adult struggling with snoring and mouth breathing, gentle daily chewing builds the muscle tone that underpins everything. I use it personally and with my own family.

❓ Adult FAQs
Is the Myo Munchee Adult safe for everyone?
It suits most people aged 14 and over. If you have significant jaw pain, a diagnosed TMJ disorder, extensive dental work, implants, or you wear braces, check with your dentist or therapist first.
Should it feel like hard work?
No. Light muscle engagement, not fatigue. If you are tensing your neck or jaw, reduce the intensity and keep it soft.
Can it help with grinding or clenching?
Yes. By strengthening and balancing the jaw muscles, regular use can reduce clenching and grinding habits over time.
How long before I notice results?
Many people notice improved muscle tone, better breathing habits and fresher oral hygiene within 2 to 4 weeks of consistent daily use.
