Yes. Nuca is safe and comfortable when used as directed.
It feels like a gentle stretch, adjustable pulsing and steady warmth. Start at the lowest of the 3 intensity levels and increase it only until it feels firm but comfortable. It should never feel sharp or painful.
Nuca never touches your teeth, so crowns, fillings and other dental work are not affected.
Yes. In a 30-day at-home user study with 400 women:
Individual results may vary.
TMJ is usually treated where the pain is felt. Dentists focus on the jaw and teeth, while physical therapists focus on the neck, so one connected tension pattern often gets treated as two separate problems.
The connection is not new. What is new is putting traction, EMS, heat and massage into one routine you can use often enough at home.
Looking down at a screen keeps the small muscles beneath your skull working overtime. When they stay tense, your jaw can tighten with them.
Nuca works on the full area in 4 ways:
So you are not only working where the pain is felt. You are also working on the upper-neck tension that may be rebuilding it.
Use Nuca for 10 minutes a day for the first 2 weeks. Lie back in bed while reading or watching TV, start at the lowest intensity and increase it only until it feels comfortable.
Once the relief begins holding, many people continue 2–3 times a week or after longer desk days.

The electricity scared me. I have crowns and I pictured it wrecking them. It is nowhere near your teeth, just a firm tingle at the base of your skull. Two years of a guard and I still woke up in pain every single morning. Now I wake up with no ache and no headache waiting for me. I'd forgotten mornings could start with nothing.
I checked my jaw a hundred times a day. Pressing my teeth together, opening in the mirror, feeling for the click. I never decided to do it, it just ran in the background all day, every day. A few weeks in I realized I had stopped. There was nothing left to check.
Nine years of soup and smoothies because chewing set my jaw off. Three weeks in I ate a steak at dinner, cut it up like a normal person and chewed on both sides. Halfway through I realized I hadn't thought about my jaw once. I eat like everyone else now.
My drawer is full of things I used twice and quit. This is ten minutes in bed with the TV on, that is the whole thing, so I actually kept it up. The guard has been in the drawer since spring and it has held. At my checkup the dentist read the wear chart twice and asked what I had changed.

Results from a 30-day at-home user study. Individual results may vary.
“Years of grinding, two cracked molars, a $300 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
“I was spending $1,200 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
“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 buyerHeat, massage and jaw tools can loosen the muscles you can reach. That relief is real.
But during long hours at a screen, the small muscles beneath your skull keep working to hold your head forward. As tension builds there, your neck and jaw can begin tightening as one connected pattern.
Nuca brings four familiar physical therapy methods into one 10-minute routine for the upper neck.
So instead of working only where your jaw hurts, you release the connected upper-neck tension too.
For the first 2 weeks, use Nuca once a day. After that, many people continue 2–3 times a week or after longer desk days.
The things you tried were not useless. They simply did different jobs.
Loosen the area where you feel the tension. But the relief can fade as the upper neck loads it again.
Hands-on work can help, but normal workdays begin rebuilding the tension between visits.
Combines the full four-part upper-neck routine in 10 minutes, whenever you need it.
Tension that has been building for years may take longer than a few nights to settle. Use Nuca through normal workweeks and stressful weeks. If your jaw and neck do not feel meaningfully better within 90 days, email us for a full refund.

Everything you need to know before deciding whether Nuca fits your pattern.
Imaging can help identify joint changes, but a muscular pattern may not appear as structural damage. What matters here is how the restriction behaves. If warmth, movement or neck work can still make the jaw easier to open, muscle is likely part of the pattern.
If the jaw stays locked, repeatedly catches at the same point or shifts sharply to one side, speak with a qualified clinician before relying on an at-home device.
Most people describe a light tingling or rhythmic muscle movement beneath the base of the skull. Start at the lowest setting and increase only to a level that feels comfortable. The device sits on the neck, not inside the mouth or against the teeth.
A night guard and Nuca do different jobs. The guard helps protect the teeth from the force of clenching. Nuca is designed to work on the muscular pattern behind that force.
Do not stop a prescribed treatment without speaking with the clinician who recommended it. Nuca can be used as part of a conservative at-home routine while you monitor how your mornings change.
The number of years does not tell you by itself whether the pattern is muscular or joint-based. The better clue is whether the jaw still changes with warmth, movement or neck work. Long-standing tension may take longer to judge, which is why the at-home trial lasts 90 days.
A static foam pad mainly provides pressure and positioning. Nuca combines 26° cervical traction, EMS, heat and massage during the same 10-minute session. The point is not the blue shape. It is the 4 jobs happening together.
Yes. Lie flat with Nuca positioned beneath the neck and use the remote to begin the 10-minute session. Follow the included setup instructions and stop if the position or stimulation feels uncomfortable.
Ask your physician or physical therapist before using cervical traction or EMS. An existing neck diagnosis requires individual guidance that a product page cannot provide.
You have 90 days to use Nuca in your normal routine. If it does not help, contact Nuca support for a refund. No return shipment is required, and the device is also covered by a 2-year warranty.
Shipping is free. Your order includes the Nuca device, hands-free remote, USB-C charging cable and the current free digital bonuses shown in the product section above. Due to high demand, delivery currently takes approximately 6-12 days, and tracking is emailed as soon as the order ships.
