1 in 4 People Suffer from Dry Mouth

Dry mouth is often linked to lifestyle or health changes, including:

  • Medication use
  • Medical or dental treatment
  • Aging
  • Travel, work, or frequent speaking
  • Conditions associated with chronic oral dryness (xerostomia)
Scientific Evidence

The Critical Role of Saliva in Oral Health

Saliva is essential for oral health. It protects teeth and gums by neutralizing acids, limiting harmful bacteria, and maintaining moisture in the mouth.

Increased Cavity Risk

Reduced saliva production can increase the risk of cavities as protective enzymes and minerals are diminished.

Enamel Damage

Without adequate saliva, tooth enamel becomes vulnerable to acid erosion and demineralization.

Gum Irritation

Dry mouth conditions can lead to gum inflammation, discomfort, and increased susceptibility to periodontal issues.

Difficulty Speaking & Swallowing

Insufficient saliva can impair normal oral functions, making speaking and swallowing uncomfortable.

Long-Term Complications

Chronic dry mouth can lead to persistent oral health complications requiring clinical intervention.

Oral Discomfort

Persistent dry mouth causes ongoing discomfort, affecting quality of life and daily oral function.

THE STORY BEHIND RHEO™

Developed by a husband-and-wife team: 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.

How to Use Rheo™

Step 1: Tuck

Tuck Rheo™ comfortably between your lip and gum.

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

Step 2: Swish

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

Once activated, the 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.

Frequently Asked Questions

Rheo™ is designed for daily use. Most people use one pouch when they need relief and replace it as needed throughout the day. Because Rheo™ delivers hours-long comfort, many users find they need fewer applications over time when compared to sprays or lozenges. Always use as directed and consult your dentist or healthcare provider if you have specific concerns.

Most dry mouth products are designed for quick, short-term moisture that fades fast. Rheo™ was created to solve that problem.

Instead of spraying, chewing, or dissolving, Rheo™ uses a discreet oral pouch combined with a dentist-formulated hydration system that supports your natural saliva production and oral comfort.

Yes, and we were very intentional about that! Rheo™ has a clean, subtle taste that feels refreshing, not weird, chalky, or overly “minty for no reason.” You’ll notice the relief, not the flavor.

    AMAZING,! INSTANT RELIEF

    I’ve been using this pouch for months now, and honestly have never had anything help my severe dry mouth as much as OPS! Almost instant relief, I can feel the saliva in my mouth activating and within 2 minutes, my mouth feels normal wetness! Not so much that I’m drooling, just the right amount that’s needed to keep me from having my tongue stuck to my mouth all day.

    My job requires a lot of talking, and without this pouch, I can barely get my words out out, stumbling over myself trying to get my point across was very difficult. My associates looked at me like, “what is she saying .” I would recommend this product to anyone with dry mouth. It has also helped me revise some teeth that we’re going bad because of dry mouth. I’m gone from thinking that we were going to have to lose all my teeth because of dry mouth to only having to replace a couple of teeth ! ONE, because I fixed the dry mouth problem and TWO, the ingredients in these pouches have been known to help with tooth decay. Build your teeth back stronger. I am living proof of this, and I will continue to use these pouches forever.!

    Life-Changing Relief for Dry Mouth!

    I’ve tried SO many products for dry mouth over the years, and the OPS Cool Rush Dry Mouth Pouches are by far the best I’ve used! These pouches provide long-lasting moisture and relief — not just a quick fix. The refreshing mint flavor is pleasant and not overpowering, and I love how discreet and easy they are to use anywhere.

    What really sets them apart is how well they stimulate saliva and keep my mouth comfortable throughout the day — whether I’m talking, eating, or just relaxing. They helped improve my oral comfort more than sprays or gum ever did. If you have dry mouth issues like I do and want something that actually works, these pouches are totally worth it. Highly recommend!
