How sleepGUARD™ 3 Works While You Sleep
The sleepGUARD™ 3 is a soft, custom-fitted oral device made from medical-grade silicone. By gently holding your tongue in a forward position, it prevents airway collapse, a common cause of snoring and mild sleep apnea. Unlike bulky masks or invasive surgeries, this simple solution improves sleep quality from night one. Engineered from patient insights and clinically validated published studies, sleepGUARD™ 3 comfortably repositions your tongue during sleep, ensuring an open airway and promoting uninterrupted breathing.
How it works:
The sleepGUARD™ 3 gently holds your tongue in a slightly forward position, preventing the airway from collapsing during sleep. This simple yet effective mechanism reduces or eliminates snoring and allows for uninterrupted breathing, leading to significant improvements in sleep quality and overall health.

from 16 reviewsI tried one, the sleepGUARD 3. I used it for about a month and it really helped with my sleep. I didn't have any discomfort

I have recently discovered this sleepGUARD 3 and it works for sleep apnea. Is it effective? Very. I feel better than I ever did with CPAP.

This sleepGUARD 3 is freakin amazing. For me it eliminated both snoring and apnea, it takes a week to get used to. And expect drooling if you don't sleep on your back. My wife says I've never been this quiet while sleeping, so I am very happy with it!

I find that sleepGUARD 3 is helpful with my particular snoring because my tongue collapses.

I do not have apnea but I am a nasal snorer and the sleepGUARD 3, when it stays on, eliminates my snoring entirely.

I've started treating my mild apnea a couple of weeks ago with a sleepGUARD 3. The first 3-4 nights of sleep were amazing, I woke up all by myself at 7:00 am feeling energized and was able to endure a lot of physical activity without feeling dead tired. I was in a good mood, my headaches were practically gone.
Mid week I almost started crying because I hadn't felt that good in years... and for fear of going back to my old feelings.

Undiagnosed OSA massively improved with tongue retainer. I was getting ready to drop a load of money on a sleep study and CPAP but the sleepGUARD 3 seems to have made a huge difference, to the point that it may be all I need.

As an anesthetist, I sedate people daily and watch them obstruct (snore) and have various techniques to relieve obstruction. One such technique is the sleepGUARD 3 which essentially lifts the tongue out of the way. This is genius!

I'm a heavy snorer who snores around 75% of the time while asleep. What worked for me is the sleepGUARD 3. They hold your tongue in place, which prevents it from obstructing your breathing and thus prevents snoring.

I was prescribed a mandibular advancement device and I found the sleepGUARD 3 worked even better. My girlfriend at the time couldn't stand it whenever I went without it.

That amazing feeling you felt the first few days is your body rejoicing in FINALLY getting some good quality deep sleep and finally being able to catch up on the deprivation it's probably been under for years. You felt awful before, so once on treatment you felt awesome in comparison.

I bought one of those sleepGUARD 3's to try it, and to my surprise it completely eliminates my snoring. It's a good price and fairly non-invasive method that I would recommend others try as well.

I had a lot of success with this. You will wake up with a weird and numb sensation in your tongue at first, but this passes. Definitely stick with it for a couple of weeks, and make sure you record yourself at night to verify the impact it's having.

I've tried several different things. Mouthguards like the SnoreRX that push my lower jaw forward which didnt help. I found the sleepGUARD 3 and have used it several times and it is very effective and eliminates nearly all of my snoring.

my wife did say that while the sleepGUARD 3 was in, I didn't snore.
