The Myo Munchee is a small chewing device made of soft, medical grade silicone. The appliance is shaped like a mouthguard, but with a handle attached.  The mouthpiece is soft, but durable, with several silicone prongs, that massage the teeth and gums. The original premise of the development of the Myo Munchee was for gum health and oral hygiene.  It became clear that there were many more benefits to be had from chewing a Myo Munchee.
