Built for Lasting Relief, Not Temporary Fixes

Relief that lasts longer, stays discreet, and fits easily into daily life.

Easy to use. Designed for real life.

Step 1: Place

Tuck Rheo™ comfortably between your lip and gum.

No chewing, spraying, or dissolving. Just place it once and go about your day.

Step 2: Activate

Moisture from saliva or a sip of water activates the proprietary hydration formula.

Once activated, the Rheo™ Pouch begins delivering immediate oral hydration.

Step 3: Enjoy

Keep it in for up to two hours while you work, talk, and stay focused.

Even after removal, Rheo™ continues to support natural saliva production and long-term oral health.

THE STORY OF OPS

Developed by a husband-and-wife team: a dentist and a pharmacist.

Oral Pouch Solutions (OPS) began with real people and a real problem. As a dentist and a pharmacist, Dr. Ryan and Dr. Rachel saw firsthand how frustrating dry mouth could be, and how few options actually worked.

So they built the solution they couldn’t find.
