~**ATTENTION TO ALL CUSTOMERS // NOT SUITABLE FOR SMALL MOUTHS**~ Our Tranquility PRO 2.0 Professional Bruxism Night Guard is the most advanced and effective product on the market. With a smaller overall size than the competing brand. Tranquility PRO 2.0 Professional Bruxism Night Guard works well because it re-positions the mouth which in turn opens the airway that gets restricted by the soft pallet when sleeping. OUR SOLUTION TO YOU: The problem with mouthpieces on the market today is that they have only one setting to re-position your mouth and they are one solid piece that can usually mold to your mouth, but they can not adjust for your personal requirements. HERE IS THE DIFFERENCE: The Tranquility Professional Bruxism Night Guard has 10 incremental, 1 millimeter, possible adjustments. Some people will need to increase incremental adjustments over time, which just isn't possible with any other mouthpiece on the market. OUR PROMISE TO YOU: The Tranquility Professional Bruxism Night Guard has great functionality with the critical added feature of being able to adjust the mouthpiece according to your personal requirement. Please confirm that this product will fit prior to purchasing.
