From the founder
I have TMJ. My dentist told me to skip her £400 guard and buy a £20 one. ClenchNoMore is what came of that advice — done properly.
I have TMJ. Years ago my dentist told me she could fit me with a custom night guard for £400 — or I could buy a boil-and-bite mouthguard on Amazon for £20 and get the same job done. She wasn't being modest. She was telling me the truth most dentists won't.
Years later, when I was looking online for product opportunities, that conversation came back. Teeth grinding was getting worse — pandemic stress, work-from-home posture, the biohacking wave — but the guards people were buying were poorly marketed, inconsistently made, and competing on price alone. Nobody was treating it like the medical-grade fix it should be.
So we did. ClenchNoMore is a UK Class 1 medical device, FDA 510(k) cleared, and biocompatibility-tested per ISO 10993 — the standard that defines safe oral contact. That's why a 4-pack lasts four months: each guard is validated for 30 nights of safe wear.
Today TheSleepGuard makes ClenchNoMore plus SnoreNoMore and a small range of sleep-quality products — all built to the same principle: medical-grade where it matters, no premium for the name on the box.
