The Aqualizer

The Doctor's Night Guard (Classic)
The AQUALIZER'S NEW TECHNOLOGY IS A MAJOR breakthrough in pain therapy. Over one million patients have used AQUALIZERS for headache, neck or shoulder pain and stiffness, facial pain, problems moving the jaw or clicking in the temporomandibular joint, stuffiness of the ears and increased sensitivity to light. Like a waterbed, the AQUALIZER has a built-in, miniature, fluid system which "floats" the jaw.
