Nuca™ Decompression Device
Why it works?
Your jaw is not deciding to do this. It is following an order from a neck that has been compressed forward for years.
A locked neck needs four things at once. Nuca does all four in one session.
Do one without the other three and you are leaning on the door instead of opening it.
Will this work if my scans were normal, or I've never had any?
Yes. That is exactly who this is built for.
Imaging finds joint damage. When the problem is muscular, there is nothing on the scan to find, which is why clean results are so common with TMJ. And most women we hear from have never been imaged at all.
The tell is not on a screen. Worst in the mornings. Worse after a heavy week at a desk. A tight neck and shoulders alongside it. That is the muscular kind, and it is the more common one by far.
Is it safe? What does it feel like?
It is EMS, the same technology physical therapists have used for forty years. Aimed at the right spot for the first time.
The first session feels like a firm tingle, then a deep ache as the locked muscle starts to let go. Never sharp. You start on the lowest setting and work up until you feel a firm pulse, not a jolt. Most women settle in the middle and stay there.
Your crowns, fillings and dental work are not affected. The pulses work on muscle at the base of your skull, nowhere near your teeth.
How and when you use it?
Ten minutes, once a day. Most women do it in bed before sleep, because that is when it matters most. It switches the order off before you sleep on it.
Lie flat on your bed, on the floor, or on the couch with the TV on. The base is non-slip, so it stays where you put it. You do not hold anything and there is nothing to learn. You lie back and let it work.
The remote sits in your hand, so you are never reaching behind your own head to change a setting.
It packs flat into a weekend bag, so a trip does not cost you a week of progress.
What to expect?
The mornings unlock first. Then a few weeks in, most women stop counting bad days, because there are not enough of them left to count.
I will admit the electricity part scared me. I have three crowns and I pictured something zapping my head. It is nothing like that. It is a firm tingle and then a deep ache, like a knot being worked out. Two years of a night guard and I still woke up locked every morning. Now I open my mouth at the mirror and there is no crack. Just quiet.
Nine years of this and I have spent more on Botox than I want to say out loud. So no, I did not believe a $99 device was going to do anything. I lived on smoothies and soup because chewing set my jaw off. Two weeks in I ate a bagel. I stood in my kitchen and teared up over a bagel. Not one doctor ever checked my neck.
I kept waiting for it to wear off, because everything else did. My guard has been in the drawer since spring. At my checkup my dentist went over the wear chart twice and asked what I had changed. I used to wake at 3am with my jaw clamped shut and lie there until morning. I sleep through now and wake up loose instead of with a headache.
I have a drawer of things I used twice and gave up on, so I expected this to join them. It is ten minutes lying in bed with the TV on. That is the whole thing. On a bad morning I could not fit two fingers between my teeth. Last Friday I got four. I stood there at six in the morning with my eyes stinging.
Your jaw was never the problem. Your neck is.
Years of forward-head posture crush the top of your spine and lock the small, deep muscles at the base of your skull. Locked, they fire a low alarm that never switches off, and your body braces against it. The first thing it braces is your jaw. All night, every night.
That is why your scans kept coming back clean. Muscular TMJ never shows on a scan, the joint is fine, and the damage shows up wherever the clench comes out. That's your teeth.
A muscle locked this long strangles its own blood supply, so it can't let go on its own. Nuca does the four things it needs at once: 26° traction opens the compression, EMS moves the frozen muscle and quiets the signal, heat restores the blood supply, and massage loosens the armor on top.
Stop clenching at home in 3 simple steps
No mouth guards, no Botox, no expensive appointments. Ten minutes a night.
Place it and turn it on
Set Nuca on a firm surface and rest your neck in the cradle.
Let the 4-in-1 therapy work
EMS, heat, massage and 26° traction release the locked muscles and quiet the signal driving your clench.
Relax for 10 minutes
Use it nightly to stop the clench at its source. Most people feel a lighter jaw within the first week.
TMJ Sufferers who Stopped Clenching
My jaw finally unclenched
"Years of grinding, two cracked molars, a 300 dollar mouth guard that did nothing. Five nights with this and I woke up without jaw pain for the first time in months. I had no idea the spot it works on at the base of my neck was the actual problem."
Sarah M. · Verified buyer
Saved me thousands on Botox
"I was spending 1,200 dollars every three months on jaw Botox. The heat and EMS actually go after the knots at the base of my skull that were causing it. Two weeks in and I cancelled my next appointment."
Rachel T. · Verified buyer
No more 2pm headaches
"I clench all day without realizing it, and by 2pm the tension headaches were unbearable. Ten minutes a night on this and within a week they stopped. I almost did not buy it because I had tried everything."
Karen D. · Verified buyerWhat to expect as the tension releases
First release

Nuca vs everything you have already tried
Your jaw is the bulb. Your neck is the frayed wire behind the wall. Everything on this list was a new bulb. The wire kept shorting.
| Nuca | Night guard | Botox | Massage | Foam pad | |
|---|---|---|---|---|---|
| Opens the compression (26° traction) | ✓ | ✗ | ✗ | ✗ | ✗ |
| Moves the frozen muscle (EMS) | ✓ | ✗ | ✗ | ✗ | ✗ |
| Restores the blood supply (heat) | ✓ | ✗ | ✗ | ✗ | ✗ |
| Loosens the armor on top (massage) | ✓ | ✗ | ✗ | ✓ | ✗ |
| One-time cost | ✓ | ✗ | ✗ | ✗ | ✓ |
| 10 min a day at home | ✓ | ✓ | ✓ | ✗ | ✓ |
Anything that does one of these without the other three is leaning on the door instead of opening it.
What one year of "managing" this costs
Every treatment above manages the clench. None of them has a finish line.
DAY
Use it for 90 nights, risk-free
If your jaw, neck or sleep is not better, email us for a full refund, no questions asked, and you do not ship anything back.
It's 90 days for a reason. A neck that has been locked for years doesn't open in a week, and you should have enough time to actually feel it let go.
Every guard, every injection, every crown you have paid for was non-refundable. This is the first thing on that list where the risk sits with us, not you.
