Good Morning Snore Solution (GMSS) Single (1) Pack - a clinically proven anti-snoring solution that is cleared by the FDA for Over-The-Counter (OTC) use as an aid in the reduction of snoring in adults 18+ years. A simple one-piece, non-custom oral appliance that holds the tongue in a forward position - it is this forward retention of the tongue that helps keep the upper airways open, which in turn aids in the reduction of snoring. Soft, flexible resin, comfortably retained within the mouth while sleeping. Adult size. Respected Calgary dentist and sleep researcher Dr. Leslie Dort is the original developer of the Good Morning Snore Solution mouthpiece. As part of her clinical practice and research at the University of Calgary, Dr. Dort discovered an ingeniously simple and effective anti-snoring strategy — tongue stabilization – which is the central idea behind the GMSS. Good Morning Snore Solution was tested using a controlled clinical study and found to be a safe, effective non-invasive remedy for snoring. Results of the clinical study were published in the peer reviewed medical journal - sleep and breathing. GMSS is a simple one-piece oral appliance that does not require any custom fitting. GMSS mouthpiece can be comfortably retained within the mouth at night while sleeping. The device has a flange that fits between the lips and teeth and a bulb with an aperture (opening) that holds the tongue. Once the bulb is squeezed to reduce the air volume, a vacuum is formed which keeps the tongue comfortably retained within the bulb. It is this forward retention of the tongue that helps keep the upper airways open, which in turn reduces snoring. If your snoring is the result of your tongue falling back and blocking your airway during sleep, then GMSS may be the best stop snoring mouthpiece to help your snoring.
