The Evidence Is Racing Ahead of the Coverage

A toothpaste company is running a study on ten thousand people. One of the things they are measuring is insurance claims.

Something is happening this year that I have been waiting a long time to see.

A toothpaste company is running a study on ten thousand people. Not to sell you whiter teeth. One of the things they are measuring is insurance claims.

Colgate launched a Phase 4 trial in May. Ten thousand people with Type 2 diabetes and gum disease. The question written into the trial’s primary outcome is whether a structured oral-health program lowers participants’ medical and dental insurance claims. (It is public. ClinicalTrials.gov, NCT07619729. You can read it yourself.)

And on the first of July, Johns Hopkins is set to launch a Phase 3 trial of more than two thousand pregnant women, testing whether a daily antiseptic mouth rinse can reduce premature birth.

Read those two sentences again. These are not fringe blogs. These are some of the most credentialed institutions on earth, spending real money, to test a thing I have been saying quietly and getting channels shut down for.

The question they are now funding is whether the mouth is upstream of the rest of the body. The people with the budgets are taking it seriously enough to spend millions finding out.

Here is the part that should make you sit up.

In the same year all of this research kicked off, Medicare moved in its own 2026 rule. The CY2026 Physician Fee Schedule added an oral-health activity that has physicians counsel patients on the connection between the mouth and the body, and document it in referrals. On paper, the system named the link.

And in that same final rule, Medicare made no changes to expand which dental care actually gets paid for. It still pays only for the narrow set of dental services tied to a handful of qualifying medical procedures. It named the connection and held the payment door where it was. (CMS-1832-F, the CY2026 Physician Fee Schedule final rule.)

So this is where we are. The research is ahead of the coverage. The institutions are spending millions to test the link, and the payment policy has not moved to match.

That gap, the space between what is being named and what is being paid for, is exactly where people fall through.

Let me make this small for a second, because that is where it actually lives.

I lost my dad suddenly. He had two infected root canals, left untreated for years, in a system that treats the mouth like a separate country from the body. I will not stand here and tell you a tooth alone killed my father, because I cannot prove that and I will not overclaim it. What I will say is that untreated dental infection is a real risk factor for the rest of the body, every clinician grants that the infection pathway is real, and his went unaddressed inside the same gaps I am describing.

I am not telling you that to be sad about it. I am telling you because the small thing and the large thing are connected. The risk factor researchers are now spending millions to measure is the same kind of thing that was sitting, untreated, in one man’s mouth.

When you read a headline about a study, it can feel far away. It is not. It is your mouth, your parent’s mouth, the gap each of us is quietly standing over.

I want to be careful about who the villain is here, because it is not the doctor.

The system trained most doctors to reach for the prescription before the root cause. That is not their fault, it is their training. The ones I am looking for are the ones who already see it differently. The doctor who treats the mouth as part of the body, not because a statute forced them to clear a patient, but because they understand why it matters.

If that is you, you are who I am building this with. The captured version of medicine will scroll past this. The good doctor will feel seen.

The villain is not a person. It is a menu that was filtered before you ever saw it, and a system with no billing code for a healthy human getting stronger.

So here is what I am actually doing.

I do not have all the answers. I am figuring this out in the open, receipts and all. What I can do is read across the research the way no single doctor has time to, hold it to an honest standard, and tell you plainly what is earning the word it uses and what is not.

The evidence is racing ahead of the coverage. I would rather we build the plan ourselves than wait for the institutions to catch up to the thing they already admitted.

If you want health that actually makes sense, and you would rather build it than wait for it, follow along. This is not a brand. It is a few people who decided to stop accepting the answer they were handed. If that is you, you are already one of us.

Questions

What is the Colgate oral health trial measuring?

Colgate launched a Phase 4 trial in May 2026 with ten thousand people who have Type 2 diabetes and gum disease. Its primary outcome asks whether a structured oral-health program lowers participants' medical and dental insurance claims. It is public on ClinicalTrials.gov as NCT07619729.

Did Medicare expand dental coverage in 2026?

No. The CY2026 Physician Fee Schedule final rule (CMS-1832-F) added an oral-health activity having physicians counsel patients on the mouth-body connection and document it in referrals, but made no changes to expand which dental services actually get paid for. It named the link and held the payment door where it was.

Is the mouth upstream of the rest of the body?

That is the question major institutions are now spending millions to test, not a settled fact. Untreated dental infection is an established risk factor for the rest of the body, and the infection pathway is granted by clinicians. Whether structured oral care measurably lowers downstream medical cost is what the current trials are funded to find out.
