How it works
Turn it on, lie back and rest your neck on it for ten minutes, ideally before bed. The device works on four levels at once: a 26° arch tractions and decompresses the base of your neck, gentle EMS pulses contract and release the locked muscles while interrupting the signal driving your clench, soothing heat opens up the blood flow, and massage works the surface tension loose. Active relief, not just pressure.
What to expect
Day 1The first session feels intense, a light tingling from the EMS as the locked muscles start to release.
Day 3–5Most people notice their jaw is not clenched when they wake up.
Week 2Tension headaches and neck stiffness start dropping.
Week 4Grinding typically stops or reduces significantly.

Your partner may notice before you do.

I wore a night guard for two years and still woke up with my jaw locked every morning. Nobody told me it was coming from my neck. I started using this for ten minutes before bed, the heat and the pulses feel incredible, and after a week I stopped waking up with a headache and have so much more energy during the day. My husband says he cannot hear me grinding anymore.

TMJ Sufferers who Stopped Clenching

Sarah M.
★★★★★

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."

Saved me hundreds on Botox

"I was spending 450 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."

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."

How it works

Stop clenching at home in 3 simple steps

No mouth guards, no Botox, no expensive appointments. Ten minutes a night.

Place Nuca under your neck
1

Place it and turn it on

Set Nuca on a firm surface and rest your neck in the cradle.

The 4-in-1 therapy goes to work
2

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
3

Relax for 10 minutes

Use it nightly to stop the clench at its source. Most people feel a lighter jaw within the first week.

The root cause

Your jaw was never the problem. Your neck is.

You spend your day looking down, phone, laptop, repeat. Years of it. That forward-head position quietly crushes the top of your spine and locks the small, deep muscles at the base of your skull.

Those muscles are some of the most nerve-dense tissue in your body. Kept locked, they fire a low alarm that never fully switches off, and your body answers it the only way it can: it braces. The first thing it braces is your jaw. All night, every night.

That is the locked jaw in the morning, the headaches, the ear pressure, the teeth that keep cracking. Not stress. A neck that has been crushed forward for years, ordering your jaw to brace every single night.

Here is the part nobody explains: a muscle locked this long strangles its own blood supply, so it can't heal itself. It doesn't need to be pressed. It needs to be moved.
How neck tension drives the nightly jaw clench

Tension before and after using Nuca
The solution

Move the muscle. Restore the blood flow. Quiet the signal.

A muscle frozen this deep won't let go from pressure alone. It has to be forced to move, contract, pump, and release, so blood floods back in and the nerve signal driving your clench finally shuts off.

That is why Nuca does four things at the same time, in about ten minutes: it tractions your neck at 26° to decompress the base of your skull, sends gentle EMS pulses that contract the locked muscles and interrupt the clench signal, adds warming heat to open the blood vessels, and works the surface tension loose with massage.

A static cradle just presses with your bodyweight. It can't contract the muscle, pump blood, or interrupt the nerve signal driving your clench. A muscle this locked has to be moved, not just pressed, and that takes power.
Where are you right now?

Clenching does not stay the same. It progresses.

1

It starts

  • Jaw tight in the morning
  • Occasional headaches behind the eyes
  • Stiff neck you blame on stress
2

It escalates

  • Pain when eating and talking
  • Daily headaches, ear pressure
  • 800+ dollars spent, nothing lasts
3

The damage

  • Cracked teeth, crowns, root canals
  • 3,000 to 10,000 dollars in dental bills
  • Irreversible wear, every night

Most people reading this are at Stage 2. Every night without addressing the source moves you closer to Stage 3.

Wake up with a relaxed jaw. No more nightly grinding, eat on both sides again.

Lasting relief

Ten minutes keeps the muscles loose for good. Relief that holds.

FAQ

Common questions

Will this give long-term relief?
Yes. Mouth guards and painkillers only mask the symptom for a few hours. Nuca goes after the root cause, it decompresses the base of your neck and uses EMS, heat and massage to release the locked muscles that drive the clench, so the tension stops coming back, not just gets covered up.
How do I use it?
Turn it on, lie back, rest your neck in the cradle, and choose a comfortable heat, massage and EMS level. Relax for 10 to 15 minutes, ideally before bed. Use it daily for the first two weeks, then whenever you feel the tension building.
What does the EMS feel like?
A gentle tingling at first that turns into a deep, rhythmic pulse as your muscles relax. Start on the lowest level and work up, lightly dampening your neck with a little water or lotion helps the EMS connect smoothly. Most people end up looking forward to it.
How is this different from a mouth guard?
A mouth guard protects your teeth from the grinding, it never stops the clench, because the clench is driven by your neck. Nuca goes after that source, releasing and decompressing the base of your neck so the nightly clench stops in the first place.
How is it different from the cheap foam pads on Amazon?
A foam pad only presses with your bodyweight. It can't contract the muscle, pump blood back into it, or interrupt the nerve signal driving your clench. Nuca adds active EMS, heat and 26° traction, that is the whole difference between pressing a locked muscle and actually moving it.
How fast will I see results?
You will feel a release the first session, but lasting change builds over time. Day 1: a looser jaw and better blood flow. Day 7: fewer morning headaches and less stiffness. Day 14+: a noticeably calmer jaw at night. Think of it like physical therapy at home, consistency is the key.
How is it powered?
It has a built-in rechargeable battery. One full charge lasts roughly 10 to 15 sessions and takes 3 to 5 hours to recharge. The charging cable is included, no batteries to replace.
Can I use it in bed?
Yes for the heat, massage and EMS, they feel great in bed before sleep. For the 26° traction to work its best, the decompression needs a firm surface to pull against, so for that we recommend using it on the floor with a mat or blanket for 10 minutes a day.
What if it does not work for me?
You have 90 days. Use it every night, and if your jaw, neck or sleep is not better, email us for a full refund, no questions, and you keep the device. The risk is on us.
How fast is shipping?
Ships within 24 hours. Due to high demand, delivery is currently taking around 6 to 12 days.
Do you sell this on Amazon?
No. To keep the price fair and protect quality, we sell exclusively here on our own site, never on marketplaces.
