Most people think about dental health the same way they think about getting an oil change. Something you do because you're supposed to. A maintenance task. A checkbox.

That thinking could be costing you years of your life.

The research is now clear: your oral health is one of the most powerful — and most overlooked — predictors of how long and how well you live. At 71, running my own longevity experiment and tracking every biomarker I can get my hands on, I've come to treat my mouth the same way I treat my heart, my brain, and my mitochondria. As a system that needs active protection.

Here's what the science says — and what I'm doing about it.

The Mouth-Body Connection Is Real

For decades, dentistry and medicine operated in separate silos. Your dentist handled your teeth. Your doctor handled everything else. That model is now officially obsolete.

Certain pathogenic oral bacteria — particularly Porphyromonas gingivalis — have been linked to systemic inflammation and a variety of chronic diseases including Alzheimer's disease, cardiovascular disease, respiratory diseases, and even pancreatic cancer. These bacteria don't stay in your mouth. They enter your bloodstream, travel to your organs, and cause damage far from where they originated.

Oral bacteria have literally been found in arterial plaques and brain tissue. Let that sink in. The bacteria living in your gums can end up in your heart and your brain. This is not a theory. This is what researchers are finding when they open arteries.

I want to tell you about a decision I made recently that surprised a lot of people — including some close to me.

I started microdosing a GLP-1 drug. And I didn't do it to lose weight.

I know what you're thinking. Ozempic. Wegovy. The weight loss drugs everyone's talking about. That's not my story. I don't need to lose weight. That's not why I'm here.

Here's what actually happened.

The Room That Changed My Mind

I attended the daVinci50 Mastermind — one of the most elite longevity-focused gatherings in the world, bringing together top physicians, scientists, and researchers singularly focused on scientific rejuvenation and regenerative medicine. These are not influencers. These are serious doctors doing serious work on extending human healthspan.

Multiple physicians in that room — independently — were recommending GLP-1 drugs not for weight loss, but for
