Relation between gut health and mouth health

There is a significant relationship between oral health and gut health. According to Andrew Huberman, oral health substantially influences overall bodily health, including cardiovascular, metabolic, and gut health. The connection between oral and gut health is crucial because they are contiguous parts of the digestive system. The oral microbiome plays a vital role in gut health, and maintaining oral hygiene can help reduce issues like irritable bowel syndrome and other gut-related problems 1 2.

Additionally, the diversity and health of the microbiome, starting in the mouth and extending to the gut, are essential for producing neurotransmitters that support brain health. Enhancing this microbiome diversity can significantly benefit the nervous system, showing how interconnected gut and oral health is with overall health 3.

Huberman emphasizes that maintaining good oral health can lead to positive effects on gut health because many bacteria enter the body through the oral cavity, not directly through the gut 1.
