Rheo™ Starter Pack
⭐️⭐️⭐️⭐️⭐️ Rated 5 stars by customers managing dry mouth
The Rheo™ Starter Pack is the easiest way to begin experiencing relief while trying two different flavors.
Each dentist formulated pouch helps hydrate, protect, refresh, and restore your oral environment in a single, discreet pouch.
Xylitol
Stimulates saliva glands for activation.
Over 530 mg per pouch for optimal saliva stimulation.
Citric Acid
Helps trigger the natural gustatory–salivary reflex to support saliva flow.
Nano-Hydroxyapatite
Helps protect and strengthen teeth, inspired by the building blocks of natural tooth structure.
Hyaluronic Acid
Helps soothe and hydrate dry oral tissues.
No other product we’ve found combines this many salivary stimulants in a single pouch to help relieve the symptoms of xerostomia.
Rheo™ is not a medical treatment and does not replace professional dental or medical care.
Hours-Long Oral Hydration
Designed to deliver sustained hydration that lasts for hours, not minutes.
Activates Natural Saliva Production
Uses multiple salivary stimulants to support the body’s natural moisture response.
Supports Fresh Breath
By promoting saliva flow and a healthier oral environment, Rheo™ helps support naturally fresher breath.
Actually Tastes Good
Lightly flavored and smooth, with no harsh medicinal taste or overpowering sweetness.
Supports Long-Term Oral Health
Formulated with dentist-selected ingredients that help protect teeth and maintain a healthy oral environment.
