How to Use

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 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.

Who Its For

Rheo™ is ideal for people experiencing ongoing oral dryness related to lifestyle or health changes, including:

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

Not a medical treatment and does not replace professional care.

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.

    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!

    Works better than melts, lozenges, or gum

    These pouches are the most discrete, long lasting, and effective option among the various products I've tried for dry mouth. One pouch lasts about 3 hours for me, there's no noticeable bump in my mouth like the melts create, and I'm not rudely sucking our chewing on anything throughout the day.
