In this solo episode, Kimberly Williamson explores the fascinating and often overlooked connection between yoga, oral health, and the brain.
She breaks down the science behind chronic stress and its direct impact on periodontal disease, explains how the vagus nerve controls salivary function, and shares what the research says about yoga as an evidence-based tool for reducing the inflammatory burden that makes gum disease worse.
She also dives into neuroplasticity, the brain’s remarkable ability to physically change its structure through repeated practice, and explains why consistent yoga and breathwork may be one of the most powerful things you can do for your whole body health, including your mouth.
This episode is grounded in peer-reviewed research and delivered in a way that is accessible for both patients and clinicians alike.
