What is the Myo Munchee chewing device?

The Myo Munchee is a small chewing device for children and adults, designed to help improve the tone and strength of the muscles in the lips, face, and jaws. Made from flexible, medical-grade silicone, it has a handle for easy gripping and lots of silicone prongs to massage the teeth and gums.

What chewing a Myo Munchee can do for you

It may look like a mouthguard but chewing on a Myo Munchee does so much more than protect your teeth. Just like any part of the body, the jaw and facial muscles need the right kind of exercise to stay healthy.

But as our modern diet of soft, processed foods requires less chewing, the lower third of our face isn’t getting the movement it needs. That’s where the Myo Munchee comes in.

Chewing: small act – big impact

The simple act of chewing helps support jaw alignment and development, promotes nasal breathing, and encourages correct swallow patterns. It can also help reduce open bite and tongue-thrust tendencies. Chewing can improve sleep and speech patterns, maintain oral tone and function, and naturally clean teeth and gums.

"It's encouraging normal function of the tongue and the swallow... that's a really important adjunct."

Invented by a renowned Australian dentist

In 1967, Australian dentist Dr Kevin Bourke pioneered a new approach to oral health when he invented the chewing device that was to become the Myo Munchee.

He spent the next 50 years researching, refining, and promoting the benefits of chewing a Myo Munchee for optimal oral health. News of his reputation spread until his dental practice became the largest in NSW outside metropolitan Sydney. Upon retirement, Dr Bourke passed the torch to the next generation. His daughter, Dr Mary Bourke, has evolved Myo Munchee into a global movement to improve oral health and development.

FAQs

  • Why chew a Myo Munchee?

    With just 10 minutes of daily chewing exercise, children and adults can improve the tone and function of muscles of the lips, face, and jaws and ensure they’re working at their best.

    Chewing on a Myo Munchee encourages lip closure, correct resting tongue placement, and swallow pattern, helping to promote nasal breathing, bone integrity and improve teeth and gum health.

  • How do I use a Myo Munchee?

    Always rinse the Myo Munchee before use. It can be submerged in freshly boiled water for 60 seconds to sterilise. Just be sure it has cooled down before use!

    Once clean, place the device in the mouth with the ‘lips’ indent at the top. Make sure the lips close around the Myo Munchee while chewing. This not only strengthens the muscles but also prevents excessive wear on the device.

    Keep chewing evenly on both sides; chewing excessively or exclusively on one side may damage or weaken the Myo Munchee. Aim for 5 minutes of active chewing twice a day as an ideal protocol.

  • How do I know what size to get?

    There are many things to think about when deciding on the right Myo Munchee for you or your child. Factors like age and stage of development will play a big part in the decision.

    Each Myo Munchee is recommended for a specific distance between the pointy (canine) teeth and comes with a general age guideline. Please use the Sizing Guide to double-check sizes before purchasing.

    If you’re still unsure, it may be best to check in with a practitioner to determine the best size Myo Munchee. Please take a look at our Practitioner Directory to find someone in your area.

  • How often do I need to use a Myo Munchee?

    We find that the optimal routine for general oral health and to keep the muscles strong is to chew a Myo Munchee for 5 minutes twice a day.

  • How do I clean the Myo Munchee?

    It’s just like a toothbrush. After chewing, simply rinse with cold running water and dry thoroughly. Once dry, please store your Myo Munchee out of UV light, in a place that allows air circulation around the device.
