Doesn’t work
I’ve tried to for three weeks and I’ve tested and it does t work. I can taste this mint in my mouth and it still smells funky. I’ve had customers and employees tell me my breath smells. I don’t drink coffeee and I brush my teeth for 10mins straight every morning and night and I also use mouth wash and I use three tabs throughout the day and it does nothing for me.

Recommended by my dental hygienist
These probiotics help maintain a healthy balance of bacteria in your mouth, which already improved my gum health and reduced bad breath. This product was recommended by my dental hygienist.

Eliminated continual bad breath and some thrush
I’ll keep this short - I’ve had oral thrush since taking antibiotics years ago. My breath was always good though so I never cared much (though I do eat probiotic-rich foods whenever I can). Lately, I started developing a gross taste in my mouth that and my wife was saying my breathe wasn’t great - not a fun thing to hear. I tried mouthwashes, general probiotics, oil of oregano, etc...nothing worked.
I bought these on a whim and began taking them just 5 days or so, my breathe is no longer bad. The thrush has minimized as well, though is still present toward my the back of my tongue. Amazing.
I don’t write reviews and wasn’t paid to do so for this product - just bought randomly, hoping it’d help, and it did. I’m sure it won’t work for everyone since everyone’s body is different, as are the reasons you might be experiencing bad breath, but for me, this is amazing.
BY THE WAY: I see reviews saying they took these like pills. That’s not going to work, you have to let them completely dissolve I. Your mouth as the instructions say!

A Lifesaver for Dry Mouth, Without That Weird Aftertaste 👏
Size: 4.3 Ounce (Pack of 1)
If you know, you know: dry mouth is not just an inconvenience, it’s downright uncomfortable. I’ve tried several brands over the years, but Biotène is the one that consistently keeps my mouth feeling fresh without that overpowering artificial mint or gritty texture.
This formula is gentle but effective, no burning, no foamy overload, and no funky aftertaste. It’s also a huge win that it’s sulfate-free and doesn’t irritate my gums like some drugstore pastes do. The mint is subtle but refreshing, and my mouth actually feels hydrated afterward (which is wild to say about a toothpaste, but here we are).
If you deal with dry mouth from medication, menopause, or just bad luck, this one’s worth every penny.
✨ Pro tip: Keep a travel size in your bag if you’re heading out for the day. Nothing ruins a coffee date like feeling like your tongue is made of sandpaper.
10/10 recommend.

Dry Mouth
Size: 4.3 Ounce (Pack of 1)
I have been diagnosed with Dry Mouth, what a problem this is! My dentist recommended toothpaste for dry mouth; I selected Biotene Fluoride toothpaste for daily use. I definitely use it at night before going to bed to help keep my mouth less dry. I also use Biotene mouth wash and other products that I'll rate another time. I love this toothpaste; I believe it's helpful for my diagnosis.
