Taking oral probiotics for bad breath can help you fight off bad breath bacteria. Probiotics are able to prevent tooth decay, gum disease and plaque buildup. They can also protect your tongue and gums.

Probiotics are available both in prescription and over-the-counter forms. These can be tablets, capsules, gummies, or foods. Every type of probiotic is different, and it’s crucial to find the one that works best for you.
