Good Morning Snore Solution® (GMSS®) is a tongue stabilization mouthpiece that has been clinically tested and proven to be safe and effective. It is FDA cleared for the reduction of snoring.

Respected Calgary dentist and sleep researcher Dr. Leslie Dort (MSc, DDS, Dip ABDSM) 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 saw potential for an alternative to the complex, uncomfortable and often expensive snoring solutions on the market. Looking at the mechanics of snoring holistically, she discovered an ingeniously simple but effective anti-snoring strategy — tongue stabilization – which is the central idea behind the GMSS®. Dr. Dort’s original mouthpiece prototypes were put through clinical safety and performance trials, and published in the peer review medical journal providing independent third party validation of the strength of the design.
