Ep. 574 This Is Destroying Your Oral Microbiome – The Fastest Way to Improve Hormones, Immunity & Longevity with Dr. Dominik Nischwitz

Apr 1, 2026

Dr. Dominik Nischwitz, a German dentist and pioneer in biological functional dentistry and ceramic implantology, explains why the mouth is the start of the gut. He covers oral dysbiosis, how hormones affect gums, risks of root canals and cavitations, mercury dangers, and why ceramic implants and hydroxyapatite toothpaste are gaining attention. Short, provocative, and health-focused conversation about oral-to-whole-body links.

ADVICE

Include Mouth Health In Whole Body Care

Integrate dental evaluation into overall health workups rather than treating the mouth as separate.
Nischwitz urges physicians and dentists to collaborate because untreated oral issues can sabotage downstream health interventions.

ANECDOTE

Personal Health Crisis Led To Biodentistry

Dominik's own health crash during dental school sparked his shift to biological dentistry.
He studied mercury dangers, trained in functional medicine, and founded Europe's first biological dentistry center around 2015.

ADVICE

Reassess Root Canals During Health Optimization

Treat root canals as short-term solutions and investigate chronic inflammation nearby.
Nischwitz warns dead root canal teeth harbor anaerobes in dentinal tubules producing toxic byproducts and often show chronic apical inflammation on 3D imaging.

Today, I am honored to connect with Dr. Dominik Nischwitz, a German dentist, pioneer of biological functional dentistry and ceramic implantology, founder of DNA Aesthetics, and the Vice President of the International Society for Metal-Free Implantology. He's also an author with a particular focus on how optimal health starts in the mouth.

In our discussion, Dr. Nischwitz explains why the oral microbiome is, in fact, the upper gut. We explore the impact of oral dysbiosis, hormonal changes in oral health, concerns about root canals, cavitations, and old wisdom tooth sites. We clarify that mercury amalgams are not benign and are known neurotoxins, and explain why big-mouth overhauls must be carefully planned. We also discuss the debate of fluoride versus hydroxyapatite, cosmetic dentistry concerns, and more.

This is another invaluable conversation that you will likely want to listen to several times.
