And a pea-sized amount of toothpaste contains about half a milligram of fluoride.

Now, if you're using 10, 20 times more than that pea size, now you're exposed to 5 milligrams, 10 milligrams of fluoride.

And you don't even have to swallow it.

This is a very small molecule, a molecular weight of 19.

So it's absorbed directly across the buccal mucosa, the oral cavity, and it becomes systemic.

No, you shouldn't.

Now, tongue scrapers, the data, again, that's time tested.

That's an ancient practice.

And even in our study, we found that people who do tongue scraping

have a more diverse oral microbiome and they seem to have better oral health.

Well, if you're going to plant a garden, do you plant a garden on untilled soil?

I grow my own food.

Okay.

So you have to till the soil, right?

You've got to break up the soil so the seeds actually can be aerated, and you break up that biofilm.

Yeah, you take the back of the dorsal tongue, I mean, almost to the point of the gag reflex, and you just pull that—

ideally copper, tongue scraper forward, and you're going to see this goop coming in there.

But it's kind of like tilling the soil, and it's increasing the diversity of the dorsal part of the tongue, the microbiome.

In that regard, yes.

But what we found was in that one kid, we saw the greatest increase in blood pressure.
