Episode Description
Most people in the biohacking world are doing everything right. They're tracking their labs, testing their sleep, optimizing their supplements, and building morning routines that would make most people's heads spin. And yet something keeps not landing the way it should. The energy isn't quite there. The inflammation markers won't budge. The cognitive clarity they're chasing stays just out of reach.
Nobody told them to look at their mouth.
Dr. Katie recorded this conversation live at Beyond Biohacking 2026 in Austin, Texas, right after holding the first-ever dental room at the conference. Dr. Ratna Indah, biological dentist and founder of California Dental Wellness, was one of the very few dentists in the building. That's part of the problem they came to talk about.
What you'll learn in this episode:
The mouth has been systematically separated from medicine, and patients are the ones paying the price. Dr. Katie and Dr. Ratna talk about what that separation looks like in practice, what it costs patients who never connect the dots, and what both of them are building to change that.
You'll hear why a room full of committed biohackers went quiet when they saw phase contrast microscopy images of what was living underneath crowns they thought were fine. You'll hear about P. gingivalis, the organism already linked to Alzheimer's disease, and why telling patients not to floss to protect their heart may be one of the most well-meaning but harmful pieces of advice in modern medicine. You'll hear Dr. Ratna's personal story of watching her mother's memory decline rapidly, then reverse, through a deeply intentional wellness protocol that started with asking better questions.
And you'll hear what it looks like to leave a group practice, start from scratch in California, and build the dental wellness center model that medicine has been quietly asking dentists to create for years.
Key moments in this episode:
Why the biohacking world keeps missing the mouth, and what changes when it's finally in the room
How silent oral infections drive systemic inflammation for years without causing a single symptom
The cardiologist advice about flossing that Dr. Ratna believes is doing real harm, and what the research actually says
Why "dental insurance" is a language problem, and what happens when you stop using that phrase in your practice
How Dr. Ratna's mother reversed significant memory loss, and the role that light therapy and biological thinking played in getting her there
What a future dental wellness center looks like, and why functional medicine doctors are already asking for it
Dr. Katie's perspective:
"When we're asking them to raise their hand, who had their wisdom teeth extracted, almost the full room, who had root canals in the mouth, majority of them. And then you show them what's growing underneath their crowns, and they realize the mouth has been upstream this whole time, dumping toxicity and inflammation into the system, and nobody ever told them to look there."
The demand for this conversation is real. The packed room in Austin proved it. Dentistry is showing up, and it's bringing the research with it.
