About Oral Pouch Solutions

Dentist-Formulated. Patient-Inspired.

We’re Ryan and Rachel, husband and wife, a dentist and a pharmacist.

We created RHEO together after seeing the same problem from two sides of healthcare.

As a dentist, I watched patients struggle daily with dry mouth and cycle through products that never lasted. As a pharmacist, Rachel saw that same frustration everywhere. People were trying sprays, gums, and lozenges that offered relief for minutes, not hours.

We knew there had to be a better way.

Here’s Why We Created Rheo™

This product started at home.

When my father, a retired dentist, went through chemotherapy, severe dry mouth became one of his hardest daily challenges. As both his son and his dentist, I searched for something I could confidently recommend. Nothing worked long enough. Nothing met the standard I would expect for my own family.

So we decided to build what didn’t exist.

Together, we created OPS RHEO, a dentist-formulated dry mouth pouch designed to work with the body, not against it. It delivers relief for hours, not minutes, using ingredients I would confidently recommend to my own patients, backed by both clinical insight and real-world use.

Before expanding beyond the dental office, Rheo™ was tested with real patients.

  • It lasts longer

    “This is the first thing that lasted long enough to actually help.”

  • It works reliably

    “It actually works when I need it to.”

  • It fits into daily routines

    “I don’t have to think about it during the day.”

What Makes Rheo™ Different

Rheo™ isn’t a spray.

Not gum.

Not a lozenge or tablet.

It’s a discreet oral pouch designed to sit comfortably under the lip and support sustained hydration over time, quietly working in the background.

Instead of momentary moisture, Rheo™ focuses on duration, discretion, and oral comfort you don’t have to manage all day.
