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.
SMART-ZINC™ TECHNOLOGY
How SmartMouth™ Works
SmartMouth™’s patented formula combines a sulfur eliminating solution with a zinc ion activating solution — kept separate until you pour. The result: bad breath eliminated instantly and prevented for 24 hours with just two rinses a day.
See it in action
Watch how the zinc ions activate.
Most mouthwashes mask the symptom. SmartMouth™ eliminates the cause — then prevents it from coming back for 24 hours.
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 solution
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.
Why sulfur gas smells so bad
The compounds bacteria produce — specifically hydrogen sulfide and methyl mercaptan — are among the most odorous substances known. Even at concentrations of just a few parts per billion, they’re immediately detectable by the human nose. That’s why bad breath can feel so persistent: the source is microscopic, but the smell is instant.
HOW IT WORKS, STEP BY STEP
Two rinses a day. 24 hours of fresh breath.
SmartMouth™ works in two ways: elimination and prevention. Every time you pour.
-
You pour the two solutions together
SmartMouth™’s dual-chamber bottle keeps the Sulfur Eliminating Solution and the Zinc Ion Activating Solution completely separate until the moment you pour them into the cup.
-
A chemical reaction releases billions of zinc ions
When the two solutions combine in the cup, a chemical reaction occurs that instantly activates billions of zinc ions. The solution turns green — that’s your signal that it’s freshly activated and ready to work.
-
The Sulfur Eliminator destroys existing bad breath
The Sulfur Eliminating Solution immediately destroys any sulfur gas already present in your mouth — giving you instant fresh breath from the first rinse.
-
Zinc ions block germs from producing more
The billions of activated zinc ions bond to the germs in your mouth and prevent them from consuming protein particles. No protein consumption means no sulfur gas production — and no bad breath returning for 12 hours per rinse, 24 hours with two rinses a day.
THE DUAL-CHAMBER BOTTLE
Scientifically designed to keep the power of zinc ion activation in your hands — every pour.
Zinc Rich Activator (blue cap)
Releases billions of zinc ions when poured — bonds to germs and prevents sulfur gas production for 12 hours per rinse.
Sulfur Eliminator (green cap)
Destroys existing sulfur gas in your mouth on contact — instant fresh breath from the first rinse.
THE COLOR INDICATOR
You activate the zinc ions.
When the two solutions come together, a chemical reaction occurs that instantly releases billions of zinc ions. Here’s what the color tells you.
Green = Ready
The solution is freshly activated and the zinc ions are ready to bind to germs. This is when SmartMouth™ is at full potency — rinse immediately.
Blue = pour again
If you wait 5 minutes after pouring, the solution turns blue — meaning the zinc ions are no longer as effective at preventing bad breath. Pour a fresh cup.
Frequently asked questions

SmartMouth™ provides fresh breath 12 times longer than any other leading mouthwash because it works in 2 ways: elimination* and prevention. (1) It eliminates existing bad breath when you rinse with it. (2) It prevents new bad breath from forming. The result is 12 hours of fresh breath after each rinse. No other leading mouthwash has been clinically proven to provide fresh breath longer than 1 hour.
Your taste buds will be thrilled with the delicious, mint taste of SmartMouth™. Unlike most mouthwashes, SmartMouth™ does not contain alcohol so it does not burn or dry out the mouth. After rinsing with SmartMouth™, your mouth and teeth will feel smooth and uniquely clean. In fact, within one week, you can wake up with your teeth feeling smooth and clean (no fuzzy feeling).
SmartMouth™ is immediately effective upon rinsing, and you can drink or eat at any time. However, when rinsing with any flavored mouthwash, you may want to wait a few moments before eating or drinking. This allows time for your palate to naturally become flavor neutral.
SmartMouth™ Mouthwash is effective at maintaining fresh breath even after eating most foods, so additional rinsing is not required. If you do introduce a very strong, food-based odor like onion or garlic into your mouth, you may need to re-rinse to eliminate that new odor.
SmartMouth™ is effective in eliminating smoker's breath, including cigar breath. As smoking re-introduces strong odor back into the mouth, you may want to re-rinse after smoking.
Post-nasal drip provides a natural food supply (protein) for bacteria to consume and produce bad breath gases. SmartMouth™ is effective in eliminating and preventing the bad breath caused by typical post-nasal drip.
SmartMouth™ Mouthwash is 100% alcohol free. Alcohol is a drying agent, and a dry mouth can cause or worsen bad breath. In fact, there are many challenges to alcohol containing mouthwashes.
All SmartMouth™ oral rinses are fluoride free.
While proper oral hygiene is essential to preventing gingivitis, there are many other factors that can influence whether or not you'll get gingivitis.

SmartMouth™ Premium Toothpaste uses zinc ion technology in conjunction with other premium features to provide enamel strengthening, anti-plaque, anti-cavity, sensitive whitening. An effective toothpaste needs to work subgingivally, meaning it can reach the difficult area between your gums and teeth.
