If you’re someone who’s deep into biohacking, you’ve probably tracked your sleep, optimized your diet, maybe even tinkered with red light, cold plunges, peptides, or nootropics. But I’ll tell you something few people in this space are talking about—and as a dentist, I say it with urgency:
None of it sticks if your mouth is working against you.
Yes, your mouth. The part of your body that gets the least attention in the biohacking world… yet often holds the most interference.

Let’s Talk About Biological Dentistry
Biological dentistry is a different animal. It’s not just about fillings and cleanings. It’s about asking: How is your oral health impacting the rest of you?
If traditional dentistry looks at teeth as isolated units, biological dentistry sees the mouth as a livewire—deeply connected to your nervous system, your immune system, even your hormones.
And let me be clear: I’m not talking about “holistic” in a feel-good, throw-some-essential-oils-on-it kind of way. I’m talking about clinical, measurable, systemic impact. Inflammation. Immunity. Energy production. Detox pathways. These are all tied to your mouth.
Your Body is Electric—Until Something Shorts It
The human body runs on electrical signals. It’s a closed-loop circuit, until it’s not. Introduce the wrong material—say, a piece of metal, a dead tooth, or a slow-healing socket—and you create an interference field.
It’s like slicing into an electrical wire and wondering why the lights dim in another room.
Dead teeth. Mercury fillings. Cavitations. Even the wrong bite. These things don’t just affect your mouth—they throw off your entire energetic system. And the kicker? Most people have no idea they’re walking around with these ticking time bombs until something bigger breaks down.
Renowned physicians like Dr. Dietrich Klinghardt and Dr. Thomas Rau report that up to 70% of chronic inflammation has origins in the mouth—yet most doctors and patients never look there.

The Oral Microbiome: It All Starts Here
You’ve heard of the gut microbiome. But what about the mouth? It’s the front door to the whole system. The terrain of your oral microbiome determines the kinds of bacteria that populate your gut—and by extension, your skin, brain, and immune system.
If your mouth is inflamed, your body is inflamed. End of story.
Root Canals: The Elephant in the Operatory
This one’s controversial, but I won’t stay silent.
A root canal removes the living tissue inside a tooth. What’s left behind is a non-vital organ—sealed shut, but still full of microscopic tubules where bacteria can hide, thrive, and pump out inflammatory signals 24/7.
In medicine, we’d never leave a dead body part in the system. In dentistry? We often do. And it costs people their health.

Metals: Why Your Fillings Might Be Zapping You
Here’s a question: what happens when you put two different metals in a conductive fluid?
You get a battery.
Now imagine that’s happening in your mouth—with your saliva as the fluid. That’s galvanic current, and yes, it’s real. I’ve seen it firsthand. Patients come in with chronic fatigue, anxiety, or brain fog, and after removing conflicting metals in their dental work, they start to feel better. Coincidence? Not likely.
Cavitations: The Infection That Doesn’t Hurt
Cavitations are another silent issue. They form when a tooth extraction site—often wisdom teeth—isn’t cleaned properly, leaving behind pockets of dead bone and trapped bacteria. These spots don’t always hurt, but they can quietly drip inflammatory cytokines into the system for years.
I've removed fatty, decayed bone that looked totally normal on an X-ray. Once it's out, the body can finally stop fighting the ghost.

The Tooth-Organ Connection is Real
You don’t have to be an acupuncturist to appreciate this: each tooth connects to an energetic meridian. That means your liver, kidneys, heart—they all have dental counterparts. It’s not woo woo; it’s well-mapped Traditional Chinese Medicine.
I use meridian charts as part of every patient evaluation. It’s not about mysticism—it’s about patterns. And patterns matter when you’re solving chronic illness.
Why Ceramic Implants Make a Difference
When replacing teeth, material matters. I use 100% metal-free ceramic implants because they integrate well, don’t conduct current, and are tolerated by the body far better than titanium. It’s not about trend—it’s about physiology.
Don’t Just Google “Holistic Dentist.” Do Your Homework.
The term “biological dentist” is getting tossed around a lot lately. But not all of us are practicing the same way. Some barely scratch the surface. Others mean well but don’t have the training.
I encourage you—whether you come see me or not—to look deeper. Ask what protocols they follow. Ask how they evaluate root canals, metals, cavitations. If they dismiss it with “if it doesn’t hurt, leave it,” keep walking.
Pain is not the metric. Inflammation is.
My Commitment to You
I didn’t land here by accident. I’ve spent years training under some of the brightest minds in biological dentistry. What I’ve learned is that healing doesn’t happen when we compartmentalize. It happens when we look at the whole system.
My job is to listen, to investigate, and to restore function—not just in your mouth, but in your entire being.
If this sparked something in you—if you’ve done everything “right” and still feel like something’s missing—maybe it’s time to look in your mouth.
There’s an interactive meridian chart you can explore at www.toothandbody.com. Use it. Ask questions. Start digging.
Because your next breakthrough might not be in a supplement or a smart device—it might be in your smile. Biohackers, it’s time to open wide. The next frontier of longevity begins at the root.
