Your Airway Blocks. You Snore. Nobody Sleeps Deeply.
Snoring is not just noise. It happens when air is struggling to move freely while you sleep and the tissues around your airway are vibrating because something is partially blocking the flow.
Snoring is not just noise. It happens when air is struggling to move freely while you sleep and the tissues around your airway are vibrating because something is partially blocking the flow.
When you fall asleep, your tongue and throat muscles relax and can fall back, narrowing your airway and causing the sound known as snoring. Blocked nose, extra weight around the neck, alcohol, aging, or even the shape of your throat can all make it worse.

On a flight, at a family visit, sharing a hotel room, snoring turns simple nights stressful. You start worrying about disturbing others, feeling self-conscious, and avoiding situations that should feel relaxed.

No complicated setup. No machines. No medications. Just a simple, non-invasive way that works with your body to stop snoring and sleep deeper.
Place sleepGUARD™ 3 in your mouth before bed. It gently supports your tongue in a slightly forward position, preventing it from collapsing back and restricting your airway while you sleep.
With your tongue better supported, your airway opens up. Snoring caused by restricted airflow reduces, and your body can breathe more freely and more consistently throughout the night.
You enjoy quieter nights and the kind of deep uninterrupted sleep your body needs to restore itself. Wake up feeling sharper, rested, and ready for whatever the day brings.
Enjoy quieter nights and wake up feeling like you actually slept.

Marcus T.
I started using Sleep GUARD about a month ago after my wife kept bringing up my snoring. The first few nights felt a little unusual, but after that I adjusted pretty fast. Biggest difference is we both stay asleep now instead of waking each other up through the night. I also feel less exhausted in the mornings.
Tom B.
I almost didn't order because spending $199 on a snoring device felt expensive to me. But after trying other options that did nothing, I finally decided to try it anyway. Glad I did. My sleep feels deeper now and my wife says the snoring has reduced a lot. It ended up being worth it for us.
Deborah K.
I had already tried nose strips and another mouthpiece before this and neither really helped. Before ordering I emailed support because I was worried about having the same issues I had with other products. They explained how the tongue positioning works and answered everything clearly. Took me about a week before sleeping with it started feeling normal.
Sandra W.
I bought this for my husband after years of broken sleep because of his snoring. By the third night I could already tell the difference. He said it took about two weeks before it felt fully comfortable, but now it is just part of his routine. Easy to clean with warm water too. Ours arrived quicker than expected and after five months still looks almost new because we took care of it.
James R.
My snoring had become a real issue at home and I was running out of ideas. I bought this expecting maybe a small improvement at best, but within the first week my children said our room were noticeably quieter at night. It is easy to clean, simple to travel with, and honestly worked better than the other things I had already tried.
Aaron F.
I travel a lot for work and wanted something small and easy to carry around. This fits easily in my bag and only takes a few seconds to put in before sleeping. Since using it I wake up feeling better when traveling. A couple coworkers I usually travel with even mentioned I seem to sleep much more quietly now.
Linda C.
I was diagnosed with mild sleep apnea and could not get comfortable using a CPAP machine. My GP suggested I try a tongue stabilizing device instead. The first several nights felt strange and I almost returned it, but support helped me adjust the positioning and suction properly. Really glad I stuck with it because after a few weeks I was sleeping much better.
Priya N.
Works well overall and definitely reduced my snoring, but I would not say it felt natural immediately. For me it took close to three weeks before I stopped noticing it during the night. Once I adjusted though, the improvement was worth it. Delivery also took about 5 days which felt a little slower than expected.
Chris M.
Good device. The support team was helpful when I had questions initially. The first couple nights felt a bit strange, so I gave it some time before deciding how well it worked. My snoring has definitely improved since then. I also track my sleep with an app sometimes and the number are noticeably much better now than before.
Michelle O.
My niece stays with us and we both snore, so I ordered a bundle of two. It was straightforward to use and the instructions were easy to follow. One thing we got comment about from my husband is how much silent the bedroom is now at night. We both seem to sleep more deeply and wake up less during the night. She noticed a difference quickly too.
Be informed. Feel confident about sleepGUARD™ 3 before your first night.
sleepGUARD™ 3 is designed to address one of the most common causes of snoring by helping keep the airway open during sleep. Many customers notice a reduction in snoring within the first few nights, and our 30-Day Sleep Better or We Make It Right Guarantee lets you try it in real sleeping conditions with confidence. Individual results may vary.
Most mouthguards work by pushing the jaw forward. sleepGUARD™ 3 works differently. It gently holds the tongue forward instead. This means no jaw soreness, no bite shifting, and no waking up with your teeth feeling out of place. It addresses the airway directly without moving your jaw at all.
sleepGUARD™ 3 is made for nightly use with soft, medical-grade materials designed to fit naturally in your mouth. Most people adjust quickly, but it can take up to two weeks for it to feel completely natural. If you are new to oral sleep devices, wearing it for a short time before bed during the first few nights can help make the adjustment easier.
Most people notice a reduction in snoring from the very first night and report sleeping more deeply as a result. For best results, use sleepGUARD™ 3 consistently each night. If you need help along the way, our support team is here to assist.
sleepGUARD™ 3 is suitable for most adults who snore and want a simple, non-invasive solution. However, if you have significant dental issues, severe jaw pain or TMJ, or are currently undergoing dental treatment, check with your dentist before use. If you have moderate to severe sleep apnea, consult a doctor before use. Discontinue use if you experience persistent discomfort beyond the initial adjustment period.
You are covered by our 30-Day Guarantee. Most customers notice an improvement within the first few nights, while it can take up to two weeks for sleepGUARD™ 3 to feel completely natural. If you are struggling with fit, comfort, or results, contact our support team first; many customers achieve the result they came for with a small adjustment. If it is still not the right fit for you, you can request a return within 30 days of delivery.
Rinse sleepGUARD™ 3 after each use and clean it daily with mild soap and warm water. Allow it to fully air-dry before storing. With proper care, sleepGUARD™ 3 is designed to provide months of regular nightly use. Replace it if you notice wear, changes in fit, or reduced comfort.
Our team is happy to help. Contact support at customer@synbulsleeping.com, and we'll get back to you within one business day.
