Probiotics Studied For Dental Caries (Cavities) Prevention
Your mouth is home to its own bustling community of bacteria, and cavities start when the 'troublemaker' bacteria get the upper hand. These bugs feast on sugars and produce acid as a byproduct — and that acid slowly eats away at your tooth enamel, like a steady drip wearing down stone. Over time this leads to the tiny holes we call cavities. Keeping the balance tipped toward friendly bacteria is a big part of protecting that precious enamel.
Just like your gut, your mouth benefits from having plenty of good bacteria keeping the harmful ones in check. Certain oral probiotic strains have been studied for helping to crowd out the acid-producing bacteria linked to cavities and support a healthier, better-balanced mouth environment. Used alongside good brushing, flossing, and dental visits, these friendly strains may be a supportive way to promote strong teeth and lower the likelihood of cavities forming.

Protecting Teeth and Gums with an Oral Probiotic Supplement
Streptococcus salivarius M18 is a naturally occurring oral probiotic that acts like a friendly guard for your mouth — crowding out the bacteria responsible for cavities, gum disease, and bad breath. Unlike gut probiotics taken in capsules, M18 works directly in your mouth as a slow-dissolving lozenge, colonizing your saliva and teeth where it's needed most. Backed by multiple clinical trials, it's become one of the most researched oral-specific probiotic strains available today.
