Frequently Asked Questions
Frequently Asked Questions
What results should I expect and when?
Most users notice visible tongue coating reduction and fresher breath within the first 3–7 days of consistent use. The key difference from every product you've tried before: results don't disappear after 30 minutes. With daily use, you're disrupting the biofilm colony's ability to re-establish — so results compound over time. 93% of users in our consumer study reported a noticeable reduction in bad breath within 30 days.
How is this different from the water flosser I already own?
Two things. First, most people use water flossers on their teeth — not their tongue. The tongue is where 43% of all bad breath originates, and it is almost never the target. Second, DewRinse includes a dedicated tongue cleaning tip specifically engineered to direct pulsating pressure across the tongue surface and between papillae. Without that tip, you're solving the wrong surface.
Why hasn't my dentist recommended this?
Halitosis treatment is not a required subject in most dental school curricula. A 2025 cross-sectional study in BMC Oral Health called for it to be made compulsory — because it currently isn't. Most dentists have no established protocol for chronic bad breath. The average sufferer waits 7 years before finding real help. That gap is documented — and it's exactly why DewRinse exists.
Won't the tongue coating just come back?
Tongue scrapers remove the surface layer — which is why coating returns within 60 minutes every time. DewRinse disrupts the biofilm colony underneath, not just the surface. With consistent daily use, the colony loses its ability to re-establish at the same rate. Most users report coating stops returning within the first week.
Is mouthwash not enough?
Mouthwash kills surface bacteria only. Bacteria inside biofilm are up to 1,000x more resistant to antimicrobials than free-floating bacteria. Mouthwash cannot penetrate the biofilm matrix. It also kills beneficial bacteria, disrupts your oral microbiome, and can make the underlying problem worse over time. It was never designed to solve bad breath — only mask it temporarily.
How do I use it?
Fill the 260ml reservoir with water. Attach the tongue cleaning tip. Select your mode. Hold over the sink and run the pulsating stream across your tongue for 60 seconds. Done. No 20-minute commitment. No special solution. No subscription. Just water and 60 seconds.
How long does the battery last?
40 days of daily use on a single charge. USB rechargeable and TSA flight-approved. The most travel-friendly oral care device on the market.
What if it doesn't work for me?
30-day money-back guarantee. No questions asked. You've already spent hundreds on things that didn't work. This is the lowest-risk purchase you'll make — because if it doesn't solve the problem, you pay nothing.
What DewRinse Does That Nothing Else Can
Tongue coating is responsible for 43% of all bad breath — and it has been almost completely ignored by the entire oral care industry. DewRinse was built specifically for the people that industry failed.
Our Unique Pulsating Hydro-Flush Technology
Meet the New Breath Standard
You've tried every mouthwash on the shelf. You've bought the scrapers, the probiotics, the oil pulling kits, the TheraBreath system. You've spent hundreds of dollars and years of your life trying to fix something your dentist told you "looks fine." What if the problem was never what you were putting IN your mouth — but what your routine was physically incapable of reaching?
Pulsating Hydro-Flush Technology
1,400 pulsations per minute at 20–120 PSI create hydraulic shear forces that penetrate between tongue papillae, shatter the biofilm matrix, and flush bacteria out from the crevices no scraper, brush, or mouthwash can reach.
3 Modes for Every Sensitivity
Clean mode for daily deep flushing. Massage mode for gum-sensitive users. Jet mode for maximum power. One device, every sensitivity level.
Dedicated Tongue Cleaning Tip
The tongue tip is the unlock. Without it, you're using a water flosser on the wrong surface. DewRinse includes a specially designed tongue cleaning tip that covers what a scraper never could in 60 seconds flat.
40-Day Battery Life
USB rechargeable and TSA flight-approved. One charge lasts 40 days of daily use.
260ml Wide-Opening Reservoir
The widest opening in its class. Easy to fill, easy to clean, no contamination risk.
Gentle Startup Flow
Pressure gradually increases from startup so sensitive gums adjust comfortably. No shock, no bleeding, no reason to avoid the routine.
