Bad breath can be a serious problem. Most everyone at some point suffers from bad breath or halitosis. So of course people are always looking for a way to cure this embarrassing problem.

After lots of testing and research, we here at Toothbrush Life, have compiled a list of the best mouthwashes for bad breath. In this list you will see the best mouthwashes to treat bad breath and how each of them specifically work.

According the ADA, over 50 percent of the population suffers from halitosis. Luckily, we have many cures for bad breath now. No one has to suffer any longer.

Before I give you the list, I’d like to show you my best recommendation for bad breath. I separated it from the rest of the list because it is more than just mouthwash, it is a full bad breath fighting kit. This kit is dedicated to stopping bad breath for good.

This kit has so many different bad breath fighting products in it that it is sure to kill bad breath from every angle. It focuses on hitting all the areas where bad breath can come from.

Bad Breath Fightng Kit

Most of you know I am always expressing my love for TheraBreath products. It’s no wonder that TheraBreath mouthwashes made our “best mouthwash for bad breath” list ranking in the number one AND number two spots.

If you have a bad breath problem, I highly recommend their TheraBreath Starter Kit which includes lots of different products to help get to the source of bad breath.

You can buy it here, but you can also see my full review and everything this kit comes with in this TheraBreath Review.

Okay so now onto the best mouthwash for bad breath list.

#1 TheraBreath PLUS Mouthwash

First up on the best mouthwashses for bad breath list is the TheraBreath PLUS Mouthwash. Now this is for the worst cases of halitosis. This stuff works WONDERS.

TheraBreath PLUS uses the same amazing formula that I brag about in their original 24 hour bad breath fighting oral rinse. But it also adds soothing aloe vera, zinc gluconate, tea tree oil and green tea which is anti-bacterial. This powerful combo makes it the strongest bad breath mouthwash.

Guaranteed to KILL bad breath and make fresh breath last.

TheraBreath PLUS Oral Rinse is an alcohol-free formula that doesn’t burn or irritate the mouth. It is very gentle and has a great peppermint flavor. It contains no artificial flavors or colors and is certified kosher, vegan, and gluten-free.

This product DOES NOT contain these ingredients : Alcohol • Saccharin • Sodium Lauryl Sulfate • Benzalkonium Chloride (an allergen)

The first TheraBreath product I ever tried is their original TheraBreath Oral Rinse. This mouthwash is the reason I fell in love with TheraBreath products.

It stops bad breath instantly. It also keeps it fresh for an incredibly long time. 24 hours long! I’ve never had a mouthwash actually keep my breath fresh throughout the entire night. Imagine waking up with no morning breath!

Dr.Katz invented this formula after learning his daughter was getting picked on for her bad breath. He discovered that bad breath comes from bacteria that die with oxygen. These are called anaerobic bacteria. He created an oxygenating mouthwash that kills the bacteria that causes bad breath.

This rinse contains no alcohol and SLS. So it is gentle, doesn’t burn and is great for those with sensitivities. It has a mild, mint flavor and contains no artificial flavors or colors and is certified kosher, vegan, and gluten-free.

CERTIFIED AS: Vegan, Gluten-Free, Kosher, Environmentally Friendly, Diabetic Friendly, Cruelty-Free, American-Made

#3 SmartMouth 24 Hours Fresh Breath

SmartMouth 24 Hours fresh breath rinse definitely deserves a spot on our list of the best mouthwashes for bad breath.

Sulfur gases are what cause bad breath. SmartMouth kills these sulfur compounds. SmartMouth has two different solutions that you mix together.

One is an odor eliminator which eliminates bad breath sulfur compounds. The other solution is the activating solution which contains zinc which stops bacteria from consuming protein. When bacteria consumes protein, that is what makes the sulfur and bad breath gases. So the production of future bad breath is stopped.

SmartMouth rinse should give you lasting fresh breath for at least 24 hours!

#4 CloSYS Mouthwash

CloSYS mouthwash is one of my favorite oral health products of all time. It has so many amazing benefits. It’s no wonder it made our best mouthwash for bad breath list.

CloSYS contains active ingredient Cloralstan. This ingredient has the power to kill 99% of bad bacteria within 10 seconds and prevents it from regrowing.

It is great for killing bad breath. CloSYS kills the bad bacteria with no gum irriation. It is pH balanced and ideal for the common sensitive patient. Kills bad breath bacteria. Doesn’t burn.

CloSYS is also good for dry mouth and mouth sores. This is also the gentlest mouthwash I have ever used. Literally taste like water.

Bonus Advice: Tonsil Stones

I would also just like to add that bad breath often stems from tonsil stones. If you are a sufferer of tonsil stones, please please do yourself a favor and check out my article on this tonsil stone removal kit review. It has worked WONDERS for my son! It got rid of his tonsil stones in 3 hours!


One of these mouthwashes are sure to get rid of bad breath for good. You really can’t go wrong with any of the above mouthwashes. Instead of just temporarily masking the bad breath, they actually get to the source and help eliminate bad breath forever.

You can buy all of these bad breath mouthwashes at your local store or even online. Bad breath relief is only a click or skip away. You don’t have to live with it any longer.
