Good Morning Snore Solution

The Good Morning Snore Solution (GMSS) is a tongue stabilizing device that was designed by Dr. Leslie Dort. This mouthpiece has been scientifically proven to stop snoring.
Because it sits outside of the mouth, some people prefer it over traditional mouthpieces which sit entirely inside of the mouth. Unfortunately, one of the downsides of this product is that you must be able to breathe through your mouth in order to use it.
Compact Design
Made from a very thin silicone material that slips over the tip of the tongue and rests outside of the mouth.
UNIVERSAL FIT
Unlike traditional mouthpieces, the GMSS does not require any fitting. It's one-size-fits-all, so it's ready to use out of the package.
SCIENTIFICALLY PROVEN
A 2008 randomized, controlled, crossover study proved that the GMSS significantly reduces respiratory disturbances and snoring.
VitalSleep

For years, VitalSleep has been the leader in the adjustable MAD category.
VitalSleep contains a screw adjustment on either side of the mouthpiece which can be turned using the provided hex key.
It’s the only mouthpiece available with a 1-year guarantee – If it breaks, they will replace it for free.
ADJUSTABLE
Unique micro-adjustment feature which allows you to fine-tune the lower tray until your snoring stops.
CUSTOM FIT
The new and improved design features a soft plastic tray lining which can be heated in warm water to create a custom fit.
2 SIZES AVAILABLE
Offered in 2 sizes - Small for women and Regular for men.
