Feed the starving masseter.
If you clench or grind at night, wake up with a tight jaw, or get headaches behind your eyes, this is for the muscle your night guard has never touched. Real heat. Targeted pressure. 15 minutes before bed.

One device. Two therapies. Fifteen minutes.
Feed the starving masseter in 15 minutes a day. Real heat. Targeted pressure. At home.

NattieRelease™ · Jaw Muscle Release Device
Heated aluminium tip at 42–48 °C plus four levels of vibration for the masseter and temporalis. USB-C, about 10 sessions per charge. The 15-Minute Jaw Reset guide included.

NattieRelease™ · Pack for Two
For the partner who clenches too — or home and travel. Two devices, £39.50 each, 100 nights to decide.
You must start with the muscle, not the teeth.
The muscle that closes your jaw, the masseter, is the strongest in your body for its size. When it clenches for hours it crushes its own blood vessels. A muscle without blood doesn't relax. It seizes. We call it the starving masseter.
Deep Heat Perfusion
The aluminium tip reaches 42 °C in under a minute and holds up to 48 °C, capped so it never burns. Real heat reopens the vessels the clench has been crushing.
TriggerPoint Vibration
Four levels, from a hum to a deep pulse, through a precision tip with an edge for scraping along the muscle and corners for pressing into the knot.
The 15-minute ritual
Perfusion, Release, Reset. One button, fifteen minutes before bed, and the muscle goes to bed fed and unloaded instead of starving and locked.
Your night guard protects your teeth. It was never built to touch the muscle.
Millions of Britons clench or grind at night. Most are told it's stress and handed a piece of plastic. The plastic protects the teeth. It was never built to touch the muscle that's doing the clenching. NattieRelease is built for exactly that muscle.
Real heat at 42 to 48 °C reopens the vessels the clench has been crushing. Targeted vibration and the precision tip undo the knot. The muscle goes to bed fed and unloaded instead of starving and locked.
Designed to supplement, not replace, your dental care.
What people say after 100 nights.
Reviews from Nattie Sleep customers.
"My dentist wanted £480 for a hard splint. I tried this first. Three weeks in, my husband asked what had happened to the grinding."
"I'd had Botox twice. Both times it wore off and came back worse. This is the first thing that changed how my jaw feels in the morning rather than numbing it for a few months."
"My wife bought it for me as a last resort before separate bedrooms. Night six she slept through for the first time in two years."

Try it for 100 nights, 100% risk-free.

Things people ask before buying.
Does it hurt or burn?
No. The tip is capped at 48 °C, the temperature physios use for tissue warming, and it switches itself off after 15 minutes. It feels like a hot flannel, not a hot pan. Start on heat level 1 and vibration level 1 the first night.
Can I keep using my night guard?
Yes, and you should for the first two weeks. NattieRelease works on the muscle before bed, the guard protects your teeth during the night. Most people stop needing the guard by week three, and you'll know when.
How long, and when?
15 minutes, once a day, ideally in the 30 minutes before bed. On a bad day, a second session in the morning.
Who is it not for?
Anyone with a recent jaw injury, a dislocation, a pacemaker, or a diagnosed joint condition under active treatment: talk to your clinician first. Not for children. NattieRelease is designed to supplement your dental care, not replace it.
Delivery and returns?
Free tracked UK delivery, 7 to 12 working days. 100-Night Home Trial with a full refund, plus a 1-year guarantee on the device.
