Probiotics Studied For Periodontal (Gum) Disease

Healthy gums are the sturdy foundation that holds your teeth firmly in place. Gum (periodontal) disease begins when harmful bacteria build up along the gumline, triggering inflammation — think of it as a low-grade fire that leaves gums red, swollen, and prone to bleeding when you brush. If that imbalance is left to smoulder, it can affect the deeper structures that support your teeth, which is why keeping your gums calm and healthy really matters for your whole mouth.

Because gum trouble is largely driven by an overgrowth of unfriendly bacteria, restoring balance in the mouth is key. Certain oral probiotic strains have been studied for helping to support a healthier balance of mouth bacteria and promote calmer, more comfortable gums. Working alongside regular brushing, flossing, and professional cleanings, these friendly strains may be a supportive way to help maintain gum health and keep that all-important foundation strong.

Protecting Teeth and Gums with an Oral Probiotic Supplement

Moderate

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.
