The Oral Microbiome: A Practical Guide

Health note: Oral probiotics are an emerging adjunctive area. Evidence varies by strain, condition and outcome. They should not replace routine oral hygiene, professional dental care, or treatment of persistent symptoms.

The oral microbiome is the community of microorganisms living across oral surfaces. Teeth, tongue, gums and saliva create different ecological niches, and microbial behavior is influenced by diet, hygiene, saliva, host factors and other conditions.

Balance is not sterility

Healthy oral care is not about eliminating every microorganism. Biofilms are complex communities, and disease involves interactions among microbes, host response and environmental conditions.

Where probiotics fit

Probiotics are one proposed way of influencing this ecosystem, but they sit alongside established oral hygiene and professional dental care rather than replacing them.
