The Power of PVS: A Breakthrough You Can Feel

At the heart of Clench Relief® Pro Rx is a patented use of PolyVinyl Siloxane (PVS) — a material trusted by dentists for decades, now available in an FDA-cleared, at-home solution for the first time. This isn’t just a feature — it’s a breakthrough in TMJ care.

Precision Fit Icon

Precision Fit, Every Time

Our PVS formulation captures the shape of your bite with microscopic accuracy, ensuring a secure, stable fit that supports proper jaw alignment and relieves pressure where it matters most. It’s the same class of material used by dentists for crowns and implants — now reimagined for home use.

Custom Care Icon

Custom Comfort

Once set, the PVS holds your jaw in a natural, relaxed position — reducing clenching and grinding while improving muscle balance and relieving tension. The flexible finish allows for wear without irritation or bulk.

FDA Innovation Icon

Patented Innovation

Clench Relief holds the first and only patent on the use of PVS in a mouthguard or splint. No other solution offers this level of dental-grade customization and clinical precision in a home-use device. This innovation sets us apart — and protects you from knockoffs that can’t deliver the same results.

Home Fab. Icon

Fast & Easy at Home

Just mix, roll, pack, and go — in under fifteen minutes. Our two-part PVS putty activates on contact and hardens quickly, so you can get relief without waiting weeks for lab processing or mail-in impressions.
