Toxicologist here. I think that take is dishonest or dumb.
Taking a lethal dose is almost never the concern with any substance in our drinking water.
Hormones, heavy metals, persistent organic chemicals, ammonia are all in our drinking water. But for all of them we can’t drink enough water to die from a high dose.
Some of them still have a large effect on our bodies.
It’s about the longterm effects. Which longterm studies to learn about. That makes them harder to study.
Still doesn’t mit flouride does anything bad longerm. But the argument is bad.
That might well be the case. I’m not sure if it is helpful to use those half truths which are simpler to convince certain people. Or if it weakens the point because it is in the end not really correct.
Pretty much anything you can think of is recommended by someone, because different people have conflicting views. The key is to choose whose recommendations are based on the best reasoning & evidence aligning with your goals.
It’s so funny I was just having a similar conversation about neurotoxic venomous animals in another thread. Lethality is an obviously concerning threshold, but there are substances out there that can easily destroy your quality of life and livelihood that never reach the concern of being lethal.
I think for mostly rational people concerned about fluoride in their water is that it was a public health decision made with little to no actual science proving it’s safety or efficacy when it was first decided that they were going to add it to the public water supply. The proposed benefits of it weren’t even supported by scientific evidence, it was just supposed that exposure to sodium fluoride could potentially reduce tooth decay for some.
Personally, I’ve suffered from the cosmetic damage of dental fluorosis, and I’m not necessarily thrilled about fluoride. But I have way more issues with public mandates founded on pseudoscience than I am with sodium fluoride. Especially now that we can see evidence that for some people fluoride can be especially beneficial.
So what was wrong with giving people the option of using fluoride toothpaste or mouthwashes… Why did it have to go into the public water supply?
It’s considered by the CDC as one of the greatest Public Health Achievements of the last Century. There have been dozens, if not hundreds of studies about fluoride affects in the water supply.
In 1945, Grand Rapids became the first city in the world to fluoridate its drinking water.The Grand Rapids water fluoridation study was originally sponsored by the U.S. Surgeon General, but was taken over by the NIDR shortly after the Institute’s inception in 1948. During the 15-year project, researchers monitored the rate of tooth decay among Grand Rapids’ almost 30,000 schoolchildren. After just 11 years, Dean- who was now director of the NIDR-announced an amazing finding. The caries rate among Grand Rapids children born after fluoride was added to the water supply dropped more than 60 percent. This finding, considering the thousands of participants in the study, amounted to a giant scientific breakthrough that promised to revolutionize dental care, making tooth decay for the first time in history a preventable disease for most people.
So the person above may think they’re so clever, or whoever fed them that factoid may think that. Notice the claim is remineralization. Maybe that’s true, it may be that a study first showed that in 1975 and that’s not contradicted by your link but that is a non sequitur. It’s not what we’re talking about, it’s not a good faith argument.
Fluoride does have long term effects though once you consider fluoride exposure through all sources like diet, which is mostly due to fluoride from water ending up in farmland. Tradesmen alone regularly exceed the upper limits due to high water consumption in hotter seasons
Yup, same with PFAS and forever chemicals. Maybe I’m ignorant because I’m not a doctor, but I don’t know if this line of thinking holds water - pun not intended.
Are you sure fluoride doesn’t? It does accumulate in the soil, building up in crops. Considering fluoride exposure from all sources, many people are above upper safe limits, even from tea drinking alone
I don’t think fluoride should be added to water as it just pollutes the environment, where 99.99% of water isn’t coming in contact with teeth
Fluoride only “accumulates” up to the peak concentration of the environment (no further) on places where it is removed from contact with that environment.
You can only accumulate fluoride in the soil if you keep adding it and there is almost no rain to wash it away.
Yes, irrigation with the minimum possible amount of water is known to destroy land for millennia at this point. But sodium will be a problem way before you notice any change in fluoride.
You just made me mad by helping me realize that the Trump bros are going to break water by removing fluoride long before they fix water by removing lead.

Yeah, it seems to me like he got the right idea and wanted to convince people by making an extreme statement…
That might well be the case. I’m not sure if it is helpful to use those half truths which are simpler to convince certain people. Or if it weakens the point because it is in the end not really correct.
Also, isn’t it recommended to not give infants fluorided water, hence why you can buy it in virtually every grocery store?
Pretty much anything you can think of is recommended by someone, because different people have conflicting views. The key is to choose whose recommendations are based on the best reasoning & evidence aligning with your goals.
Also “because I’m an expert and I say so” is a good way to convince someone to let you poison them.

Mate, your entire second paragraph is completely false. Like, you need to just read this: https://www.nidcr.nih.gov/health-info/fluoride/the-story-of-fluoridation
It’s considered by the CDC as one of the greatest Public Health Achievements of the last Century. There have been dozens, if not hundreds of studies about fluoride affects in the water supply.
Yeah that proves my point entirely.
In 1945 they fluoridated the first public water supply.
In 1979 the first published research began to appear to show how fluoride might be able to remineralize dental enamel.
Yeah, I guess that somehow totes proves his point. Super easy to see the world wrong when they have the reading comprehension of a 6th grader.

Yeah, by this argument lead in the water isn’t a concern.
Yup, same with PFAS and forever chemicals. Maybe I’m ignorant because I’m not a doctor, but I don’t know if this line of thinking holds water - pun not intended.
Yeah but lead bioaccumulates where as fluoride/ine doesn’t

It doesn’t. This is high-school chemistry.
Fluoride only “accumulates” up to the peak concentration of the environment (no further) on places where it is removed from contact with that environment.
You can only accumulate fluoride in the soil if you keep adding it and there is almost no rain to wash it away.
Like how crops are irrigated with town water, and in many areas with lowering rainfall? Accumulates in fruit, vegetables, leaves too
