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

Tooth Anatomy and Health

Huberman explains the layered structure of teeth, with enamel as the outer layer and dentin beneath it. He highlights the process of remineralization, where minerals are added back to the enamel to fill in cavities that have started to form. The importance of saliva in maintaining oral health is discussed, as it plays a crucial role in supporting remineralization and keeping the mouth healthy. Huberman also touches on the role of gums in providing a seal between the oral cavity and the deeper layers of the body, emphasizing the significance of gum health in overall oral health.

Formation of Cavities

Huberman explains that cavities are not caused by specific foods like sugar but by bacteria, particularly Streptococcus mutans, that feed on sugar and produce acid. This acid demineralizes the tooth, leading to the formation of cavities. He highlights that Streptococcus mutans is a communicable bacteria that can be passed on through activities like sharing glasses, bottles, or kissing on the mouth. The importance of maintaining a balanced pH in the mouth to support remineralization and prevent cavity formation is emphasized.

Importance of Oral Microbiome

Huberman discusses the significance of the oral microbiome in maintaining oral and overall bodily health. He explains that the mouth is a vulnerable yet robust environment filled with bacteria, and the balance of good and bad bacteria is crucial for oral health. Supporting the proper bacteria in the mouth and eliminating harmful bacteria through daily protocols can improve oral health and prevent issues like periodontal disease. The role of saliva in supporting the oral microbiome and remineralization is highlighted as a key factor in maintaining oral health.

Daily Protocols for Oral Health

Huberman provides insights into simple and cost-effective daily protocols for maintaining oral health. These protocols include brushing and flossing regularly, avoiding acidic and sugary foods, and supporting remineralization through proper saliva production. He also emphasizes the importance of nasal breathing at night to prevent dryness in the mouth, which can impact oral health. By following these daily protocols, individuals can improve their oral health, support remineralization, and prevent cavity formation.

Impact on Overall Health

Huberman discusses the connection between oral health and overall bodily health, highlighting how oral health can influence cardiovascular health, metabolic health, and even brain health. He explains that maintaining a healthy oral microbiome and supporting remineralization can have positive effects on various bodily systems, reducing the risk of diseases like Alzheimer's and cardiovascular issues. By prioritizing oral health and implementing daily protocols, individuals can improve their overall health and well-being.

Fluoride

Fluoride is a substance that strengthens tooth enamel by replacing some of the natural bonds with stronger ones. However, there is a debate about the safety of fluoride, with some concerns about its impact on thyroid and brain health. Huberman suggests filtering drinking water to reduce fluoride exposure if necessary.

Habits to Avoid for Oral Health

Huberman highlights the importance of avoiding certain habits that are harmful to oral health, such as alcohol consumption, stimulants, smoking, vaping, and excessive sugar intake. These habits can disrupt the pH balance in the mouth, leading to demineralization of the teeth and increased risk of cavities.

The Benefits of Intermittent Fasting on Oral Health

Intermittent fasting is suggested as a way to create optimal conditions for saliva production and remineralization of the teeth. By avoiding food and acidic liquids for extended periods during the day, individuals can support their oral health and reduce the risk of cavities.

The Importance of Brushing at Night

At night, when saliva production is reduced, Huberman recommends brushing teeth, flossing, and cleaning the mouth to minimize the opportunity for bacteria to feed on sugars and create acid. This nighttime oral care routine is crucial for maintaining healthy teeth and preventing cavities.

Brushing and Flossing Techniques

Huberman recommends using a soft toothbrush and brushing in a circular motion on the fronts and backs of the teeth. He also suggests brushing the gums lightly to promote circulation and reduce sensitivity. When it comes to flossing, he advises gliding the floss down the side of the tooth, getting underneath the gum, and using a circular motion before lifting it up between the teeth.

Xylitol and Toothpaste

Huberman introduces Xylitol as a low-calorie sweetener that can inhibit the growth of cavity-causing bacteria like streptococcus mutans. He suggests using toothpaste containing Xylitol for its benefits in promoting oral health. Additionally, he discusses the controversy surrounding fluoride in toothpaste and provides alternatives for those who prefer fluoride-free options, such as toothpaste with hydroxyapatite.

Mouthwash Recommendations

Huberman warns against alcohol-based mouthwashes, as they can disrupt the oral microbiome and deplete the mucosal lining of the mouth. He advises using non-alcohol-based mouthwashes or antiseptic mouthwashes prescribed by healthcare professionals for specific conditions. For those looking for cost-effective alternatives, he mentions using baking soda and water as a toothpaste and creating a high salt solution for a dental rinse.

He also discusses the potential risks of using hydrogen peroxide in oral rinses and recommends a high salt solution for dental rinses instead. This cost-effective approach can help maintain oral health without the need for expensive products.

Impact of Oral Health on Gut Health

Huberman explains the relationship between oral health and gut health, highlighting how bacteria from the mouth can affect gut microbiota. By promoting a healthy oral microbiome, individuals can potentially reduce symptoms of irritable bowel syndrome and other gut-related issues. This connection underscores the importance of oral health in maintaining overall digestive health.

Dental Procedures and Fillings

Huberman addresses common concerns about dental procedures, including the safety of metal fillings and sealants. He discusses the potential risks associated with metal fillings containing mercury and advises individuals to avoid disrupting them to prevent mercury exposure. While routine dental cleanings are essential for removing tartar and identifying cavities, he emphasizes the need for personalized care based on individual oral health needs.

Frequency of Dental Visits

Huberman explores the recommendation of visiting the dentist twice a year for routine cleanings and check-ups. While these visits are crucial for evaluating oral health status, he suggests that the frequency of dental visits may vary based on individual factors such as genetic predispositions and oral hygiene practices. Dentists aim to promote daily oral health protocols to reduce the need for frequent cleanings and maintain optimal oral health.

Additional Oral Health Practices

Huberman briefly mentions other oral health practices like oil pulling and vitamin D supplementation, acknowledging that these methods may have potential benefits but require further research. He encourages individuals to explore different practices and determine what works best for their oral health needs. By incorporating a holistic approach to oral health, individuals can enhance their overall well-being and reduce the risk of various health conditions.
