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.
