The human mouth contains an estimated 100 billion to 1 trillion bacteria, comprising over 700 different species. These microorganisms play various roles, including aiding in digestion and protecting against harmful pathogens. While the presence of bacteria can sound alarming, most of them are harmless and are part of the body’s natural ecosystem. Regular oral hygiene helps maintain a balanced oral microbiome.
