RHR: Your Mouth is Talking To Your Brain—And You Should Be Listening

RHR: Your Mouth is Talking To Your Brain—And You Should Be Listening

Author: Chris Kresser July 7, 2026 Duration: 25:08

What if one of the most overlooked risk factors for cognitive decline isn’t in the brain—but in the mouth? In this episode of Revolution Health Radio, Chris Kresser explores the emerging science linking oral health to brain health. He examines how chronic gum disease may contribute to cognitive decline, Alzheimer’s disease, and Parkinson’s disease through systemic inflammation, direct bacterial migration to the brain, and disruption of the oral-gut-brain axis. Drawing on recent research, Chris explains why periodontal disease should be considered a key factor in dementia prevention, why this conversation remains absent from mainstream care, and practical steps listeners can take to protect both oral and long-term cognitive health.
