Best Bad Breath Treatment Mouthwashes of 2026

"This product is great for freshening your breath before brushing your teeth. I love it! I apply 3 drops directly onto my toothbrush, brush my tongue a few times, add toothpaste, and then proceed with my normal brushing routine. It keeps your breath fresh for most of the day, even after eating! If you still experience bad breath after using this, I would recommend a detox or colon cleanse, as bad breath usually originates from your stomach, not your mouth."

"I was initially skeptical about these drops. I suffer from tonsil stones and always worry about having bad breath. Despite never being told that my breath is bad, I've been obsessed with maintaining oral hygiene since developing the stones during pregnancy. Despite regular flossing and brushing, my mouth never felt clean. However, after using this product, I noticed a significant difference in how my mouth felt. It's small enough to carry everywhere, even in your pocket, and I use it throughout the day, even just rubbing it on my gums, teeth, and tongue. It effectively eliminates the smell of coffee, morning breath, onions, and more."

"I absolutely love everything about this product. It has numerous uses. Adding two drops to a small cup of water creates an excellent breath freshener that's safe and easy for my kids to use too. Applying a drop on the toothbrush with some toothpaste enhances the minty freshness. My son wears retainers at night and used to need two rounds of brushing in the morning to eliminate bad breath. Not anymore! It's incredibly fresh and pleasant. I also appreciate its compact size, making it easy to bring with us everywhere."

"Firstly, the mouthwash has a refreshing minty flavor that leaves my mouth feeling cool and rejuvenated after each use. The taste isn't too strong, which I appreciate.

In terms of effectiveness, this mouthwash does a wonderful job. It helps eliminate bad breath and leaves my mouth feeling clean and fresh for hours. It also provides me with confidence knowing that it's killing germs and promoting better oral health.

What I especially like about this mouthwash is that it doesn't cause any uncomfortable or stinging sensation. It's gentle on my gums and doesn't cause any irritation, which is a significant advantage for anyone with sensitive gums like me!"

"After two weeks of use, I found that it really helped a lot. It's very effective in preventing bad breath and keeping the mouth fresh. However, it doesn't completely get rid of bad breath, which is slightly disappointing! You can use it two or three times a week to maintain fresh breath and overall, it's worth it!"

"This is truly the only mouthwash you need. If you use it consistently, it effectively eliminates bad breath, not only immediately but also later in the day (like post-work, post-coffee breath). My husband is a habitual coffee drinker and used to come home with unpleasant breath, but ever since we started using this, I've noticed a significant improvement in his breath."

"I use this mouthwash in a unique way - it's excellent right before a make-out session. I brush my teeth to ensure my mouth is generally clean, then just before things heat up, I swish with this mouthwash. It leaves your mouth tasting clean and moist to your partner, without the overpowering minty taste of toothpaste. It simply provides a fresh and moist mouth without the 'trying to cover up bad breath' taste."

"My dental hygienist suggested this product after a deep cleaning session. I started using it and fell in love with it. It doesn't burn and leaves your mouth and breath feeling refreshed. Some reviews mentioned a chlorine smell, but after 1-2 uses, it's hardly noticeable. The product is so effective that I ordered a second bottle for my teenagers who don't floss or use their waterpik daily. One of them had persistent bad breath despite thorough brushing. After a week of regular use, this product eliminated his bad breath. This product truly works!"

"I've always brushed my teeth and used mouthwash, but I've struggled with lingering bad breath for years. This made me uncomfortable getting close to people or even taking flights. After trying this product, for the first time in years, I can go through the day with just one swish in the morning and still have pleasant breath when I get home. This is incredible! I feel confident again and am even considering taking flights and looking forward to being close to people. This product is a lifesaver! Please give it a try! I'm about to purchase the toothpaste as well - just take all my money!"

"I've struggled with bad breath my entire life and tried nearly every mouthwash, including Therabreath, without success. However, this is the only product that has worked for me. I also began taking oral probiotics and using a tongue scraper, which has significantly helped. Prior to using this mouthwash, I used to wake up with terrible breath that would return a few minutes after brushing. Now, I wake up with decent breath, and the freshness lasts for hours after brushing. I feel much less self-conscious when talking to people. My only criticisms are its overly sweet taste, which lingers long after rinsing, and its high price. However, I believe it's a worthwhile investment for those with chronic halitosis."

"My dentist recommended this mouthwash to maintain healthy gums. Both my husband and I love it! It doesn't sting like many other mouthwashes and effectively controls his bad breath caused by sinus infections."

"I've suffered from bad breath and a bad taste in my mouth my entire life, despite spending thousands on dental work. The latest attempt was having my tonsils removed due to foul-smelling stones. It's been incredibly embarrassing. I've tried numerous solutions to stop the smell, including cutting out sugar/carbs. I was one step away from scheduling an EGD to investigate the issue. However, after my dental cleaning, I received this product from my dentist's office. I used the mouthwash and toothpaste after eating, brushing, and flossing. For the first time in years, my mouth feels, tastes, and smells clean."
