Oral Health as the Seventh Pillar: Its Profound Impact on Brain & Body Health

This episode of the Huberman Lab podcast introduces oral health as the critical seventh pillar of mental health, physical health, and performance, alongside the existing six pillars: sleep, sunlight, nutrition, exercise, stress management, and relationships. Dr. Huberman emphasizes that oral health extends far beyond just clean teeth and fresh breath, encompassing the entire oral cavity, including the oral microbiome, palate, and tonsils. He highlights its inextricable links to cardiovascular, metabolic, and brain health, asserting that neglecting oral health can contribute to systemic diseases, including neurodegeneration like Alzheimer's, through mechanisms such as bacteria crossing the blood-brain barrier.

The podcast delves into the fundamental biology of teeth, explaining their layered structure of enamel and dentin. A key distinction is made between demineralization (De Min) and remineralization (Remin), processes that continuously occur in the mouth. Crucially, the episode reveals that teeth possess the remarkable ability to remineralize and repair cavities, provided they haven't penetrated too deeply into the dentin layer. This process is largely dependent on the pH of the mouth, which in turn is governed by the quantity and mineral content of saliva. Saliva, often dismissed as mere 'spit,' is presented as an incredible fluid vital for rebuilding tooth strength and supporting the health of the oral cavity, gut microbiome, and the body as a whole.

Dr. Huberman challenges common assumptions about oral hygiene, suggesting that even diligent brushers and flossers (Category 1) might be inadvertently disrupting their oral health due to a lack of up-to-date information. He categorizes individuals into three groups based on their oral care practices, implying that many conventional methods, while maintaining aesthetics, may deplete overall bodily health. The episode stresses the importance of supporting beneficial oral bacteria and eliminating harmful ones, underscoring the role of the gums as a critical seal preventing bacteria from entering the bloodstream and bone, which can lead to severe periodontal disease.

Practical insights and recommendations are promised, focusing on zero-cost and low-cost daily protocols. These include strategies to optimize saliva health, encourage remineralization, and maintain a balanced oral microbiome. The critical importance of nasal breathing, especially at night, is highlighted as a preventative measure against oral dryness, a leading cause of tooth decay. The episode sets the stage for detailed, science-backed protocols, emphasizing that by prioritizing comprehensive oral health, individuals can significantly improve their overall brain and bodily well-being, often with cost-saving benefits.

"oral health including the oral microbiome the health of your pallet your tonsils indeed the entire oral cavity is an extremely important component of General bodily health"

"we are going to add oral and gut health as the seventh pillar of mental health physical health and performance"

"your teeth have the ability to literally fill back in cavities that have formed provided those cavities haven't gone too deep into the teeth layers yet"

"saliva While most people think of it as just spit is an incredible substance fluid that contains all sorts of interesting and important things that allow you to rebuild the strength of your teeth"

"the gums are providing a seal between the oral cavity and essentially the bone and the general bloodstream"

"perodontal disease is associated with all sorts of really bad stuff including Alzheimer's"

"there's literally evidence that the specific bacterias that cause recession of the gums can cross the blood brain barrier if they make it into the general circulation and potentially cause Plax and Tangles some of the Hallmark features of neural degeneration in Alzheimer's"

"the critical critical need to be a nasal breather at night and not a mouth breather not just for sake of staving off sleep apnea but also because turns out the dryness of the mouth is one of the ways that you really can throw off your oral health in major ways"
