They're sitting there in an anaerobic, low oxygen environment, and they're just eating away at your jawline. They're just like us do. They metabolize, they take stuff in, they poop waste out. Those waste products accumulate, it shuts down voltage, and they eat away at your jawline. So then you've got osteonecrosis, osteomyelitis, and you don't even know it. And an x-ray will not show it.
And most dentists, unfortunately, still use x-rays instead of a higher resolution CT.
Well, I think the most important thing we've learned is what you shouldn't be doing. So it's not what should we do, it's what we shouldn't be doing. Number one, we have to get rid of fluoride. You know, just this past weekend, I was speaking at a dental conference in Salt Lake City, and there were people there from the National Toxicology Program. which in the U.S.
is the organization tasked with, if there's any kind of risk of exposure of environmental toxicant, they're charged with doing the toxicology studies to see if there's an increased risk. What is the risk? And is there a safe level that is without risk? And what they report is that fluoride, there's no benefit of fluoride, and it's all risk. It lowers IQ in kids by as much as seven points.
and it shuts down your thyroid function, and it's a neurotoxin. And as I mentioned before, most toothpaste has fluoride in it. And if you read the back of your toothpaste, it will tell you, at least in the US, I don't know about in other countries, but it says, if you swallow this, call poison control. Because it's a poison. They're putting poison in toothpaste.
And then if you also pay attention, it says only put a pea-sized amount of toothpaste on your toothbrush. A pea-sized. But everybody that I know fills the entire bristle of the toothbrush with toothpaste. So that's about 10 or 15, sometimes 20 pea-sized amounts of toothpaste. 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 soils?
So you have to till the soil, right? You 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. If you tongue scrape and use antiseptic mouthwash, that's the absolute worst scenario.
Just think about this. You're tongue scraping, you're opening up the pores, and now you're using mouthwash. It's better to easily penetrate deep in the crypts of the tongue and more effectively kill the bacteria.
Absolutely. And no antiseptic mouth rinse. Okay.
No, I think that's a good proactive practice because you need to look at the health of the gum tissue and the gingival tissue. And a routine clean and scraping the plaque off the teeth and making sure you have good mineralization of the enamel of the tooth is good, but never let them do a fluoride rinse on you.
Yeah, there's also data showing that if you use mouthwash, you lose the cardioprotective benefits of exercise. So think about this. We know that diet and exercise is the best medicine. And many people aspire to do that. They go and they try to eat good. They avoid the temptations of sugars and sweets. They exercise every day to try to increase their longevity and cardiovascular health.
If you do that and you're using mouthwash, you no longer get the benefits from exercise. And we've already established you don't get the nitric oxide benefits from diet. So two out of three Americans wake up every morning and use a mouthwash. And two out of three Americans have an unsafe elevation in blood pressure.
Well, because you're killing the oral microbiome that's partly responsible for production of nitric oxide.
Without nitric oxide, you get constriction of blood vessels, and it leads to high blood pressure.
