I thought it was a scam
Honestly, I bought Nitey mostly to quiet my wife down. 'Another thing that won't work,' I thought. But after the first night I woke up without a sore throat, and my wife had actually slept through the night.
We're sleeping in the same bed again
After 3 years in separate bedrooms, our relationship was at a breaking point. Not because of arguments, but snoring. Nitey gave us our closeness back. We now fall asleep hand in hand again.
Saved our marriage
My wife was so sleep-deprived she was talking about moving to the guest room permanently. I felt like a burden. The first night with Nitey, she cried with relief. It sounds dramatic, but it's true.
The dentist suggested trying it first
My dentist said I could pay $1,200 for a custom-made mouthguard or try Nitey first. Same principle, she said. Nitey worked perfectly and saved me a lot of money.
First real sleep in years
I had forgotten what it feels like to wake up rested. No headache, no dry mouth, no angry partner. Nitey changed my mornings, and with that, my whole days.
From skeptic to repeat buyer
I ordered with low expectations and the guarantee as a safety net. Now I've bought three more: for my dad, my brother, and the coworker who's always complaining about being tired.

Quiet by the second night
The first night I woke up a couple of times because it felt new. By the second night I slept through, and my wife said she didn't hear a thing. Molding it took five minutes with a mug of hot water.

Bought it for him, I'm the one who sleeps now
I'd been sleeping on the couch two or three nights a week. He was skeptical but tried it for me. Three weeks in and I haven't used the couch once. The Duo was the right call, the spare lives in his travel bag.

Works, but give your jaw a week
It does what it says: the snoring is mostly gone according to my phone recordings. The first four or five mornings my jaw was tight, so I kept it on the neutral setting until that passed. Now I'm one step forward and fine.

Reply from Nitey
Thanks for the honest timeline, Tom. A week of mild tightness is normal, and starting at neutral is exactly right.

Half the price of the one my dentist offered
My dentist quoted me well over a thousand dollars for a custom device and said an adjustable one like this is the same principle. Same result for me, and I can re-mold it if my teeth shift.

Why you snore, and how Nitey stops it
1Your throat relaxes.
As you fall asleep, the muscles in your throat go slack. The soft palate and the base of your tongue sink back and the airway narrows.
2The tissue starts to vibrate.
Air has to squeeze through the gap. The soft tissue flutters with every breath, and that flutter is the snore your partner hears.
3Nitey holds your jaw forward.
A few millimeters is enough. Your lower jaw brings the tongue forward with it, the airway opens, and the room goes quiet.
Fitted at home in two minutes.
1Mold it
Warm Nitey in hot water for 30 seconds, place it in your mouth and bite down. It takes the shape of your teeth in about two minutes.
- 2
Set it
Start at the neutral setting. If you still snore, move the lower tray forward a little. It adjusts up to 8 mm.
3Sleep
Put it in before bed. With your jaw held slightly forward, your airway stays open and the snoring stops. Rinse it in the morning and keep it in the case.

What a sleep specialist says
“Mandibular advancement devices are one of the most effective non-invasive ways to reduce snoring. Holding the lower jaw forward keeps the airway open during sleep.”
The clinical practice guideline of the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine (2015) recommends oral appliances of this kind over no treatment for adults who want help with snoring.
Questions people ask
Most people notice less snoring from the very first night. In our customer survey, 94% reported a clear reduction within a week. It can take two or three nights to get used to wearing it.
Try Nitey for 60 nights, risk-free. If it doesn't stop your snoring, we refund you. How it works, step by step, is on the guarantee page.
Snoring happens when the airway narrows during sleep and the soft tissue in your throat vibrates. Nitey holds your lower jaw slightly forward, which keeps the airway open. It's the same principle dentists use in custom mouthguards that cost $1,000 or more.
Some people feel mild tightness in the jaw or teeth for the first few mornings. It usually fades within a week as you get used to it. Start at the neutral setting and only move it forward if you still snore. If discomfort doesn't go away, stop using it and talk to your dentist.
It's made of soft, medical-grade silicone and has a low profile. Most people stop noticing it after the first week. You can still breathe through your mouth while wearing it.
Warm it in hot water for about 30 seconds, place it in your mouth and bite down gently. It takes about two minutes, and you can re-mold it if the fit isn't right the first time.
Yes. Nitey adjusts up to 8 mm. Start at the neutral setting and move it forward a little at a time until the snoring stops and it still feels comfortable.
Yes. Nitey holds your jaw in position whatever position you sleep in.
If you have braces, dentures, loose teeth, ongoing dental work or jaw (TMJ) problems, talk to your dentist before using Nitey.
Nitey is designed to reduce snoring. Loud snoring with pauses in breathing or gasping can be a sign of sleep apnea, which needs a doctor's diagnosis. If that sounds like you, talk to your doctor before using Nitey.
Nitey is made of medical-grade silicone that is BPA-free, latex-free and hypoallergenic.
With nightly use and proper care, a mouthpiece lasts up to 6 months, often longer. Rinse it after each use and keep it in the storage case.
