SMART-ZINC™ TECHNOLOGY
Sulfur gas is the real cause of bad breath.
Most mouthwashes mask it. SmartMouth eliminates it — for 24 hours — with just 2 rinses.
The Problem
Germs + protein = sulfur gas
Bacteria in your mouth eat protein from saliva and release stinky sulfur gas. That’s bad breath — and normal mouthwash just covers it up.
The Answer
Zinc ions block the gas at the source
When our two solutions combine, they activate billions of zinc ions that block germs from producing sulfur — preventing bad breath for a full 24 hours.
THE SCIENCE
How SmartMouth works
The two solutions have to be kept separate until the moment you pour — that’s what activates billions of zinc ions. Pour it in, use it fresh.
- Two chambers, two solutions — kept apart until you pour
- Pouring combines them — activating zinc ions instantly
- Green means fresh and ready · blue means pour again

What people are saying
“This is the one mouthwash I’ve ordered over four times, and I’ll keep ordering it. Nothing else has helped my dry mouth or bad breath, especially after meals with onions. I only need to use it in the morning and at night.”
“I’ve been using this mouthwash for 8 months as the last step before bed, and it’s made a huge difference in how clean my mouth feels and my morning breath.”
“I have been using SmartMouth for years now and find it to be the best mouthwash on the market. It is effective for eliminating bacteria and bad breath better than any of the other mouthwashes I have used.”
“I just want to say thank you for this amazing product. For years I have struggled with dry mouth due to my autoimmune disease. In just 24 hours, I saw a major improvement. Now I feel confident in pursuing my dreams. Your products are truly a lifesaver. I will be a customer for life!”
“I love SmartMouth and have been using it for years. As a cigar smoker, it’s important to know that this fantastic mouthwash exists. Now they’ve improved their dispensing system. Awesome family owned company, which I love supporting.”
“You win… I tried to not have fresh breath after rinsing with SmartMouth by eating garlic, onions, fermented beans, pepperoni, and coffee. But my breath was fresh again after an hour of eating those things. I am a fan for life.”
