How to Improve Oral Health & Its Critical Role in Brain & Body Health

About this video

Huberman argues oral health deserves promotion to a seventh pillar of mental and physical health alongside sleep, light, nutrition, exercise, stress management and relationships, because the mouth and gut are one continuous system affecting cardiovascular, metabolic and brain health. He explains that teeth can remineralise early cavities and that saliva is central to that rebuilding process, with the best window during the daytime when saliva flow and pH are favourable. Huberman therefore suggests leaving stretches of a few hours without eating or sipping acidic drinks so saliva can do its work, framing gaps between meals and intermittent fasting as oral health opportunities, not just metabolic ones. He reviews low-cost and zero-cost protocols for restoring and maintaining oral health.
