Why Your Oral Microbiome Might Be the Missing Link in Your Wellness Journey with Dentist Dr Katie Lee
In this episode, I’m joined by Dr Katie Lee, a functional and biological dentist, to explore the crucial yet often overlooked connection between oral health and whole-body wellness.
We dive deep into the oral microbiome and why your mouth is the real starting point of your gut health, immune function, and even fertility.
Dr Katie shares the science behind bleeding gums, dental inflammation, and the real reasons cavities and gum disease are more than just mouth problems.
We also explore how to strengthen your (and your child’s) oral microbiome and the surprising systemic effects of poor oral hygiene from heart disease and Alzheimer’s to hormonal imbalance and infertility.
This conversation is packed with actionable tips, the truth about tongue scraping and flossing, and how testing your oral microbiome might be the most important test you haven’t done yet.
