SmartMouth = SmartScience™

Learn the real science behind bad breath and how SmartMouth works to block it for 24 hours


Germs? Food? Digestive system? Although these play a role, the primary culprit is sulfur gas. The cause of bad breath, or halitosis, is a naturally occurring process everyone experiences almost every day. Our mouths contain million of germs, and as these germs break down protein particles in our saliva, they produce foul-smelling sulfur gas that we perceive as bad breath.

Though the problem is virtually universal (100% of the population has experienced the problem daily in the form of morning breath, and at least 10% suffer from a more serious bad breath problem), bad breath is a social taboo that can destroy our confidence and interfere with relationships.


SmartMouth works differently than single-liquid mouthwashes because our patented two-solution oral rinse stops and prevents sulfur gases, which are the real cause of bad breath. When mixed together, SmartMouth’s two solutions, the Sulfur Eliminating* Solution, which destroys sulfur gases, and the zinc-rich Activating Solution, activate to release millions of zinc ions. This zinc ion technology blocks the germs’ ability to ingest protein particles, which stops sulfur gas production and the resulting bad breath.

How SmartMouth Works


So how does it work? SmartMouth has two important solutions. The Sulfur Eliminating Solution contains an odor eliminator which eliminates existing bad breath sulfur gases. The Activating Solution contains zinc, which activates when poured to stop bacteria from being able to consume protein, and therefore stopping the production of sulfur and bad breath gases for 12 hours per rinse.

When you mix the two solutions together, it releases billions of zinc ions. This zinc-ion technology blocks the germs' ability to ingest protein particles. No protein particles, no new sulfur gas production, which means no new bad breath. Rinsing with SmartMouth Mouthwash eliminates bad breath sulfur gases and then prevents them from coming back for at least 12 hours. And how is it so effective? SmartMouth offers a unique, dual-bottle delivery system that allows you to mix the key solutions right before you use them. This makes sure that SmartMouth is freshly activated every time you rinse. Just two rinses a day gives you the confidence of fresh breath for 24 hours. SmartMouth is recommended by dentists and the only activated oral rinse clinically proven to instantly eliminate bad breath and prevent it from returning for 12 hours per rinse.

SmartMouth Mouthwash doesn't mask bad breath. It stops it at the source. Prevention is the key to overcoming the problem of bad breath, and SmartMouth is the way to achieve real, lasting results. Just two rinses a day will put your worries about embarrassing bad breath to rest and allow you to go confidently through your days and nights.


How SmartMouth Works

Pour Both Liquids Together Into The Mouthwash Cup

SmartMouth’s two different solutions must be kept separate before rinsing. The key to its effectiveness relies on the mixing of solutions right before rinsing.

Zinc Ions Activate When Poured

When the two solutions come together, a chemical reaction occurs that instantly releases an abundance of zinc ions, the key to 24 hours of fresh breath protection.

When you first pour the rinse, you'll notice a green color. That means the SmartMouth is freshly activated and the Zinc ions are available to bind to bacteria. If you wait 5 minutes after pouring, you'll notice the solution has changed to a blue color. That means the Zinc ions are no longer as effective at preventing bad breath. So remember, always use your SmartMouth when it's freshly activated!

Rinse Immediately

Rinse immediately after combining, for 30 seconds, to introduce the most zinc ions into your mouth. These are essential in the prevention of sulfur gas, the real cause of bad breath.

Bye, Bye Bad Breath — for a Full 24 Hours!

Rinsing with the activated solutions eliminates bad breath and blocks it for 12 hours, so used in the morning and at night, SmartMouth has been clinically proven to stop bad breath for 24 hours.
