Why Your Mouth—and its Microbes—Are the Secret to Whole-body, Life-long Health

Pioneering dentist Dr. Staci Whitman pulls readers into this wildly underexplored universe and presents the new science and surprising links between the microbial menagerie on your tongue, teeth, and tonsils to dementia, fertility, diabetes, heart disease and cancer.

Ultra processed foods, sugary sodas, polluted air, and chronic stress have shrunk our faces, crowded our teeth, and altered our saliva dramatically. This imbalance has fuelled systemic inflammation—quadrupling stroke risk, doubling heart disease odds, and potentially nudging Alzheimer’s progression. SPIT is the antidote to this pending oral microbiome crisis.

Transforming complex science into a thrilling road trip through our bodies and outlining clear lifestyle changes, (like ditching alcohol-based mouthwash and trying tongue-scraping), Dr. Whitman provides a new and pioneering map for improved health and longevity.
