#172: How to Prevent Cavities Using an Ancestral Diet with Dr. Steven Lin

Season 1, Ep. 172

The biggest misconception when it comes to tooth decay is that it’s an infection of harmful bacteria, in large part from eating sugar, but it’s not. Tooth decay actually results when the body doesn’t have adequate fat-soluble vitamins, which causes an imbalance of the oral microbiome.

Dr. Lin’s practice is founded in root cause protocols to prevent developmental issues associated with crooked teeth, and the biological basis of nutrition focused oral-systemic and mouth-brain connection. 

In this episode, Dhru and Dr. Lin talk about the connection between our oral health and overall health. They discuss how tooth decay is a condition we can prevent, and how we have the ability to heal cavities and reverse tooth decay in certain circumstances. They also talk about Dr. Lin’s protocol for reversing tooth decay.

-What contributes to tooth decay (8:07)

-The specific nutrients we are missing in our diet that are contributing to tooth decay (16:25)

-How to reverse tooth decay (24:30)

Season 1, Ep. 193
As people interested in health, we often tackle every major concern or follow every wellness trend—diet, exercise, gut health, oral health, and the list goes on—before we realize how important inner mental and emotional work is as well.When we’re willing to get quiet with ourselves and go deeper, that work pays off for not just our mindset, but every other area of our health, too. Spending more time at home throughout this pandemic has certainly provided the opportunity to do that work. Today on The Broken Brain Podcast Dhru talks with his good friend Dr. Mary Pardee about her experience looking inward and embracing self-care that is more than just physical.Dr. Pardee is a Naturopathic Medical Doctor and a Certified Functional Medicine Doctor who specializes in integrative gastroenterology and hormone balancing in Los Angeles, California.She is the founder of modrn med, a telemedicine and virtual wellness company that provides medical and health services to clients from the comfort of their homes.

Dr. Mary talks about the way our spiritual health and fulfillment can affect the immune system and alter our resilience against things like mold, stress, and other insults. They also talk about how Dr. Mary is counseling her patients through their decisions around the COVID-19 vaccines. As a Functional Medicine practitioner, Dr. Mary is adamant about looking at each individual’s unique story and she shares what considerations she and her patients take into account with the conversation around vaccines.
