The cavity-causing bacterium. S. mutans turns sugar into enamel-dissolving acid. Typically present at low levels (under 0.5%) in healthy mouths. Higher levels reflect cariogenic conditions — frequent sugar exposure, infrequent brushing, or both. Lower is better.
Reduce frequent sugar exposure (especially sucrose), brush twice daily with fluoride toothpaste, and consider regular kefir or live-culture yogurt — fermented dairy reproducibly lowers S. mutans counts.
Frequent sugary snacks and drinks throughout the day. The damage isn't from a single sweet treat — it's from constant sugar exposure that keeps S. mutans in acid-producing mode.
