Does SmartMouth work?SmartMouth is a mouthwash that claims to be able to freshen your breath up to 12 hours. While at first this sounds great, there are a few things to consider about having permanently fresh breath, the first of which is whether or not it actually works.

Fresh breath. It comes in handy when you’re up close and personal, but can also play a part in office dynamics, and is just nice to have at most times. You can try chewing gum or keeping breath mints handy, but that’s not very convenient, and sometimes it’s just not feasible. Mouthwash has been around for decades, but only provides temporary and fleeting salvation of what’s clinically known as halitosis.

The Claim
The claim that will get most people to at least give SmartMouth a try is that you will have minty fresh breath for a solid 12 hours. This means that you’d be covered throughout the day, and all night so you don’t wake up with the dreaded morning breath. It’s pretty much a set-and-forget answer to bad breath, and one that would let you leave the gum and mints at home.

They claim that they were able to prove the effectiveness of their product to the BBB, and that after sending them the clinical evidence that it works the BBB confirmed that it does in fact do what it claims to. Whatever your thoughts are about the Better Business Bureau, it does seem like their claim has more clout by being verified rather than simply being stated.

The Hype
Bad breath doesn’t need any hype, because it’s a somewhat universal problem that most would be happy to solve. There are tons of toothpastes and mouthwash varieties, each trying its best to help with the problem of halitosis. The 12 hour claim is all the hype this needs, since most mouthwash available only works for an hour, maybe a bit more, even if it says it does.

The Cost
Smartmouth is definitely more expensive than most of the mouthwashes out there. A one month supply is $22 at Amazon. Compare that to a 32 ounce bottle of Listerine for $7 and it’s clear that it’s not cheap to have your breath as fresh as can be all day.

The Commitment
They say that you use this just as much as you’d use any mouthwash you’re probably already used to. Just brush your teeth and use this afterward in the morning and they say you’re covered all day. Use it again at night and they say you can avoid morning breath. That’s it, just twice a day and you’re supposed to have fresh breath 24/7.

The feedback on SmartMouth is pretty convincing, with it almost unanimous that this works well and despite the high price point is still a good deal. It’s nice that they don’t use alcohol in this, so you won’t get that burning sensation that you do with brands like Listerine. One thing to note is that they don’t make many claims, if any at all, as to this fighting germs or bacteria, and only trump up it’s odor killing properties.

You have to mix a solution from two different bottles each time you use this. This is so the active ingredients can mingle together right before being swished around in your mouth. It’s their reaction that causes the magic to happen, so it’s important to keep them separated until right before using it.

One thing to consider is that perhaps you don’t want to have minty breath all of the time. Does it interfere with the food that you eat at lunch and dinner, giving it a minty overtone? Also, there are reports that it doesn’t last for the full time for some users, and it’s been noted that some foods are able to overpower it and come through, think the worst offenders like garlic and onions.

Final SmartMouth Review

We’re giving SmartMouth the Solid Try rating. It’s hard to ignore the positive feedback it gets, and it makes sense that a couple of halitosis experts have cracked the code on this one. There are a few naysayers that say it didn’t work for them, but the overall majority definitely think the benefits are worth the higher cost.

Our Recommendation
If you can look past the price this is worth having around, maybe not for daily use, but on days when it’s vital that your breath smell great, like on an interview or a first date. For daily use it’s not very practical, as few could justify spending $44 a month on mouthwash. But if your career relies on close contact with others and you’ve been told that you have a problem in this area, it may be worth it to fix it once and for all and not have to worry about it.

What do you think? Does SmartMouth work or not?

It’s hard to imagine that a mouthwash could keep your breath fresh even after eating, but if it’s getting good user reviews, then I’m not gonna argue with that. You know 22 dollars is awful expensive for a mouth wash.. I’ll give it a try but I’ll be really bummed out if it ends up being a bust.

I’m very unimpressed with this review. You couldn’t take the time to try it yourself? So your website should be called You don’t DO anything, just read other’s reviews. Of course most are going to be positive, most reviews are fake on the internet.

Starting in January of 2015, I started getting bad breath problems. My husband said “all these years of marriage and you hardly ever had bad breath, but now you have it all the time” I tried an expensive body cleanse thinking that would do it. No. I tried all the things to mask it, but they didn’t work. I would even have bad breath while chewing the strongest of gum or rinsing with strong mouthwash. This went on for 7 months, until I discovered this product. I was doubtful, but now I am amazed! My husband hasn’t complained about my breath since. It truly works. I’m about 2/3 through the bottles and I plan to buy more when I run out. I highly recommend this product!

Hi just a suggestion to have a checkup with an ENT. Both my kids developed horrible, noxious, unsolvable breath stink problems (at different times) and it turned out they had something called ‘cryptic tonsils,’ which causes food particles to lodge in little pits and grooves in the tonsils and ROT. So gross. They both had to have their tonsils out, but it was definitely worth it.

It really works, even after eating I find my breath stays fresher. (If I can’t brush, I just rinse my mouth with water.)
Regarding the concern of it staying minty and ruining the flavor of food, the mint taste fades after a while, but your breath stays completely neutral.

I buy it at CVS for about $14/ bottle. And I’ve learned that I can use about 1/3 amount of product than what they suggest. Making this expensive product go much further.

Heard about this on the Joe Madison Satellite Radio show. Went straight to Walgreen’s to purchase it. Haven’t had bad breath since. Not even morning breath (Crazy!!), according to my wife….

Yes, it works. However, I also use another in addition since the retirement community I moved to does not have flouride in the water supply, and Smart Mouth does not contain flouride. It is only to control bad breath, and it does an excellent job.

Yes, it does work for killing bad breath, but, it leaves a sort of film in my mouth that changes the flavors of food. Not in a good way either. If you’ve ever used zinc products, like Zi-cam, you’ll know what I mean. It leaves that same aftertaste in your mouth and changes flavors of foods and drinks – even water. I love that it works on bad breath, but the price needs to come down. I’m thinking the packaging with 2 separate ingredients is causing the expense.

Excellent product, however, the original version consisting of 2 SEPARATE BOTTLES was much easier to use than new 1 bottle squeeze together version, because the control flow doesn’t work 50/50 like it should. It’s either too much of 1 side & not enough of the other.
