Dry Mouth Treatment | Rheo™ Oral Pouches by OPS
There’s no miracle cure. But there is relief that lasts.
You’ve tried the sprays, gums, lozenges, and melts. Here’s a dentist-formulated pouch that actually lasts hours — and supports your teeth while it works.
A drawer full of sprays, gums, and lozenges — and your mouth is still dry.
Let’s be honest: searching for a “miracle cure for dry mouth” usually ends in disappointment. Sprays vanish in minutes. Gum wears out your jaw. Lozenges are just sugar. Melts leave a bump on your gum. None of them last, and most do nothing for your teeth.
Rheo™ isn’t magic — it’s engineering. A precision pouch that releases a hydration formula slowly, so one pouch keeps working for hours instead of minutes, while xylitol and nano-hydroxyapatite help protect your enamel.
- Relief that’s gone in minutes. You reapply all day and still feel dry.
- Products that ignore your teeth. Sugary lozenges can make dental problems worse.
- Awkward, obvious, or messy. Sprays and melts aren’t something you want to use in public.
- Money spent on things that don’t work. A drawer full of half-used products that let you down.
What actually makes a dry-mouth product work
After trying everything, most people realize the fix has to do four things at once.
Last for hours
Contact time is everything. A few minutes of relief will never keep up with all-day dryness.
Support real saliva
The best solutions stimulate your own saliva instead of just coating your mouth.
Protect your teeth
Dry mouth raises decay risk, so the right product should strengthen enamel, not add sugar.
Be discreet & easy
If it’s awkward to use, you won’t use it when you actually need it.
Relief in three easy steps
No routine to learn. One pouch, whenever you need it.
Tuck
Slip one pouch comfortably between your lip and gum. No chewing, spraying, or dissolving.
Swish
A small sip of water or your own saliva activates the hydration formula right away.
Enjoy
Keep it in for hours of comfort — and it keeps supporting your natural saliva after it’s out.
Four active ingredients, one pouch
Thoughtfully engineered by a dentist to hydrate, stimulate saliva, and protect your teeth.
Xylitol
Stimulates natural saliva and helps starve decay-causing bacteria.
Nano-Hydroxyapatite
Helps protect and strengthen enamel, the building block of teeth.
Hyaluronic Acid
Attracts and holds moisture to soothe dry oral tissue.
Citric Acid
Triggers the body’s own gustatory-salivary reflex.

They tried everything. Then they tried Rheo™.
“These pouches are the most discreet, long-lasting, and effective option among everything I’ve tried for dry mouth. One lasts about 3 hours.”
“I’ve tried SO many products over the years — the OPS pouches are by far the best I’ve used. Long-lasting moisture, not just a quick fix.”
“This is one of the first dry mouth products I actually recommend to my patients.”
“We built the dry-mouth solution we couldn’t find for our own patients.”
Rheo™ was created by a husband-and-wife team — Dr. Ryan, a dentist, and Dr. Rachel, a pharmacist — who saw every day how few dry-mouth products actually worked. Most only masked the problem for a few minutes. So they engineered a pouch that lasts, supports your natural saliva, and protects your teeth while it works.

Your dry-mouth questions, answered
Is there really no cure for dry mouth?
There’s no single “cure,” because dry mouth has many causes. The goal is consistent relief: sustained hydration plus saliva support, which is exactly what Rheo™ is built for.
How long does one pouch last?
Most people get hours of comfort from a single pouch — far longer than a spray or lozenge that fades in minutes. Many reviewers keep one in for 2–3 hours.
Is it safe to use every day?
Yes. Rheo™ is sugar-free, alcohol-free, nicotine-free and made in an FDA-registered facility. It’s designed for daily, long-term use. It is not a medical treatment and doesn’t replace professional dental or medical care.
Will it damage my teeth?
The opposite — it’s formulated with xylitol and nano-hydroxyapatite to help protect enamel and support a healthier mouth while it hydrates.
Can I use my HSA or FSA?
Yes. Rheo™ is HSA/FSA eligible — just select the option at checkout.
