How to Improve Your Teeth & Oral Microbiome for Brain & Body Health | Dr. Staci Whitman

About this video

Huberman speaks with functional dentist Dr. Staci Whitman about oral health as a pillar of gut, brain, heart, hormone and fertility health. Dr. Whitman argues that many people damage their oral microbiome in pursuit of white teeth and fresh breath, describing how products with astringents, alcohols, foaming agents and strong essential oils effectively carpet-bomb the mouth, when oral health calls for a less-is-more approach. Huberman explains that the episode covers exactly how to brush and floss for maximum benefit, tongue scraping, oil pulling, fluoride, tongue ties, deviated septums and canker sores. In the later discussion, Dr. Whitman explains that oral bacteria can survive stomach acid, notes links she draws between oral pathogens and serious diseases, and describes saliva testing mailed in a vial as a way to identify them, with a dentist guiding treatment, which sometimes involves antibiotics. She favours a less-is-more approach over preventive antibiotic rounds, partly because repopulating the gut and oral microbiome is harder than people think.
