Episode notes
Oral Microbiome Diversity
- A healthy oral microbiome, like the gut, thrives on diversity, not sterility.
- Most oral microbes (98%) are beneficial, aiding immunity and nitric oxide production, crucial for blood pressure regulation.
Mouthwash and Blood Pressure
- Over-cleaning the mouth, especially with antimicrobial mouthwash, can disrupt nitric oxide production.
- This disruption may contribute to high blood pressure by limiting beneficial bacteria.
Catherine's Oral Health Journey
- Catherine Dahl developed C. diff after antibiotic treatment for mastitis, highlighting gut dysbiosis.
- Years later, similar oral dysbiosis, caused by mouthwash and harsh toothpaste, led to inflamed gums and cavities.
