ORAL MICROBIOME & THE MOUTH-BODY CONNECTION

The Gateway to Systemic Disease Nobody Is Monitoring.

The mouth harbours over 700 bacterial species in a complex ecosystem that is entirely distinct from the gut microbiome. When oral dysbiosis develops — driven by commercial mouthwash, fluoride toothpaste, antibiotic exposure, sugar, and chronic mouth breathing — specific pathogenic bacteria colonise the gum pockets and enter systemic circulation via the highly vascular periodontal tissue. Porphyromonas gingivalis has been identified in Alzheimer's brain tissue. Fusobacterium nucleatum drives colorectal cancer progression. Oral bacteria trigger platelet aggregation and arterial inflammation that precede cardiovascular events. The oral-systemic connection is one of medicine's most under-appreciated disease pathways — and it begins with what you put in your mouth every morning.
