If you've searched for "neurostimulation for sleep bruxism" — or landed here from a paper about contingent electrical stimulation — you're probably looking for one specific thing: a device you can wear tonight that electrically stops your jaw from grinding.
Here's the honest answer, before anything else: that product isn't on sale. Not from us, not from anyone. What you've read about is a real line of research, and for a few years there was a real device carrying it. It was discontinued. That gap — between validated science and something you can actually buy — is the whole reason this page exists.
So let's go through what the research says, what happened to the product, and what genuinely exists today.
What "contingent electrical stimulation" actually means
The idea behind CES is straightforward. A sensor watches the jaw muscles during sleep. When it detects the muscle activity associated with grinding, it delivers a small electrical stimulus — not to shock you awake, but to prompt the muscle to ease off. "Contingent" simply means the stimulus only fires in response to detected activity, rather than running continuously.
This has been studied properly. Jadidi and colleagues ran controlled work on exactly this question in 2011 and 2013, looking both at whether the approach changed jaw-muscle activity and — importantly — at what it did to sleep quality itself. That second question matters more than people assume: anything that reduces grinding by fragmenting your sleep has traded one problem for another.
We're deliberately not quoting effect sizes from those studies here. They were conducted on other devices, with their own protocols and sample sizes, and treating another product's trial numbers as if they described ours would be exactly the kind of borrowed credibility we've built this company to avoid.
What happened to GrindCare
GrindCare was the device that took this approach to market. It was a small unit worn on the temple that detected jaw-muscle activity overnight and delivered contingent stimulation. For a while it was the answer to the question you're asking.
It is no longer sold.
That's worth sitting with, because it's the pattern in this category rather than the exception. Devices in the bruxism space have a habit of appearing, demonstrating something interesting, and then quietly vanishing — leaving the published research stranded with nothing available to act on it. If you've spent an evening reading promising abstracts and then failed to find anything purchasable, you weren't searching badly. There genuinely isn't much there.
Why we don't call what we do neurostimulation
We make a wearable sensor that reads jaw-muscle activity, and it can respond with a gentle cue. On the surface that sounds adjacent to what you've just read about. It isn't the same thing, and we'd rather be precise than borrow the more impressive-sounding word.
What JawSense ONE is not: it sends no current into your brain. Nothing is implanted, nothing is clinical. It makes no treatment claims — it's a wellness product, CE and UKCA marked as consumer electronics under the Radio Equipment Directive, not as a medical device. It doesn't diagnose or treat any condition.
What it is: a sensor that reads your own muscle signal, and a gentle cue — the same sensory channel a sound, a smell or a touch already uses — timed to your jaw's own activity and calibrated to a threshold you set. The mechanism we're working with is awareness and repetition. Behavioural retraining, not intervention.
Every sense you have is, in the loosest sense, "stimulation" — that's what senses are for. Our cues use that ordinary channel, gently, on purpose. Calling that neurostimulation would make it sound like something it isn't.
Why a gentle cue can reach you at all while you're asleep
The reasonable objection: if you're unconscious, how does any cue do anything?
Night-time jaw activity isn't spread evenly through the night. It clusters around micro-arousals — brief moments of lighter sleep when the brain surfaces without waking (Lavigne et al., 2003). Those are precisely the moments when sensory input is still being processed: a name said across a room, a hand on a shoulder. A well-timed, well-calibrated cue lands in that same window.
What it gives your nervous system is the one thing it has never had at night: a signal that the behaviour is happening. Awareness, in light sleep. Repeat that pairing over weeks and neural plasticity does the ordinary, unglamorous work it always does.
Whether that retraining endures once the cues stop is still an open question. We'd rather tell you that than sell around it — which is why our programme measures your nights at the start and again at the end, so you get an actual answer rather than an impression.
What actually exists today
The Jaw Activity Assessment. Two nights with the sensor in your own bed, then a plain-language report of what your jaw actually does — how often, how long, how hard — plus a one-page summary for your dentist. If your nights come back quiet, we tell you that too. €200, one-off, device on loan, ships to the Netherlands and Belgium.
The Night Programme. Twelve weeks: a measured baseline, nine weeks of gentle night cues calibrated to your own signal, and a re-measurement at the end. It's application-gated and runs in small cohorts of fifteen. Cohort 1 sold out last spring; Cohort 2 starts in September.
The free app, which works everywhere and needs no device: awareness check-ins, a symptom diary, starter exercises and intro education.
And if you're not sure any of this is you, the two-minute jaw quiz is the honest place to start — it routes you to whatever's actually appropriate, including "nothing, for now".
The short version
The neurostimulation research for sleep bruxism is real and worth reading. The device that carried it to market is gone. Nothing currently on sale will electrically stop your grinding tonight, and anyone telling you otherwise is worth a second look.
What you can do today is measure the thing first — and then work on it with cues gentle enough to leave your sleep alone. That's slower than the device you were hoping to find. It has the advantage of existing.

JawSense ONE is a wellness product. It measures jaw muscle activity; it does not diagnose, treat, cure or prevent any condition, and it is not a substitute for professional advice. If you have persistent or severe jaw symptoms, a jaw that locks, or pain when chewing, see a dentist or doctor.
