Perfect for Daily Use

These lozenges are sugar-free and gentle enough for daily use. This oral probiotic has become a staple in my morning routine. My breath stays fresh, and my gums feel robust. An excellent choice for anyone seeking oral probiotics for bad breath.

Dentist Recommended Quality
Size: 60 Count (Pack of 1)
My dentist suggested looking into oral probiotics, and I'm so glad I found this one. It's made in the USA with high-quality ingredients. This oral probiotic has noticeably improved my gum health and breath freshness. A superior bad breath treatment for adults.

Fantastic & rapid results for me! Highly recommended.
Size: 60 Count (Pack of 1)
I was pleasantly surprised how well and fast this worked for me. I purchased it to see if it would resolve some dark staining of my tongue. After about 3 days of taking it as suggested on the label (dissolve 1 tablet in mouth at bedtime after brushing teeth), I saw significant improvement, and by 5 days I observed no further staining and a completely normal looking pink tongue. Fantastic and quick results for me, but others outcomes may of course differ. As a side benefit, it has reduced bad breath when waking up. Easy to take, pleasant & very mild taste, affordable, and perhaps worth trying

I love that this oral probiotic supports both my breath and my gum health. The blend of 7 strains is impressive. My mouth feels cleaner and my teeth feel smoother. It's a comprehensive bad breath treatment for adults that delivers on its promises.
