Oh yeah? And what if someone ignores that, simply lies and says it's toxic? I'm convinced!

So, once again, DHMO is the chemical we need to fear.
The stuff also known as hydric acid. People just don't talk enough about how corrosive it is. Plus, it gets in the air and gets in your lungs!
There was an incident involving it on April 14th 1912 that took over 1500 lives.
I had the misfortune of eavesdropping on a conversation recently where some guy who was working in a bourgeoisie brewing facility recently switched jobs to work at a waste water treatment center and he was advocating for removing fluoride from water with a level of rationale that I have to assume he picked up from co-workers parroting information they heard on the Joe Rogan podcast.
Used to be a thing about it turning your teeth green
The fluoride added to water gets it up to 0.7mg/liter.
That ends up to be 2 or 3 drops in a 55 gallon drums worth of water. Not much.
Fluoride is a natural substance and is found in many areas drinking water already. Many areas in much higher concentrations than 0.7mg/liter, so realistically people all over the world have drank fluoridated water for thousands of years.
You have to well over double the 0.7 before any health issues may appear and the first to appear is at about triple the concentration in kids under 8 years old who drink it for years getting spots on their teeth. The spots are only superficial.
Going into concentrations even higher than that CAN cause health issues when drank for longer periods of time. All of those cases being from naturally occurring fluoride, which actually effects somewhere north of 20% of the world's population.
Which makes the argument that fluoride in our water keeps us passive as being extra stupid, since water sourced around Columbia (the country) is far higher than .07mg/liter and Columbia seems to be caught in violence and turmoil and instability quite a bit over the decades.
*edit: Colombia
Small note: the country name is spelled “Colombia,” and spelling it correctly means you don’t need to specify which one!
Fair enough!
Its presence in groundwater is how we discovered it's good for teeth.
In fact, there used to be so much in some areas,it actually stained the teeth. In Colorado Springs a dentist noticed that the children were developing brown stains on their teeth. In researching it, it was discovered that the "Colorado Brown Stain" was caused by excessive fluoride in the drinking water. But it also lead to the discovery that regions with natural fluoride present but in lower levels than Colorado Springs didn't have stained teeth, but did have lower levels of tooth decay.
Yep. In fact, 21% of the world's natural drinking water used falls within the recommended range for fluoride, while over another 20% is higher and in some countries actually does cause some non-superficial side effects and problems. Those don't pop up until in concentrations at least 3 times higher than recommended.
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.
Also, isn't it recommended to not give infants fluorided water, hence why you can buy it in virtually every grocery store?
Yeah, by this argument lead in the water isn't a concern.
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.
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.
Also "because I'm an expert and I say so" is a good way to convince someone to let you poison them.
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
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?
but what about my precious bodily fluids?!?
"Have you ever seen a commie drink a glass of water?"
I don't avoid women, Mandrake, but I do deny them my essence.
But what about our precious bodily fluids?
I don't avoid women, Mandrake, but I do deny them my essence.
It's not about toxicity, it's about mind control! Fluoride makes you passive. But you know this since you're a tool of the government pushing poison.
Just bleach your teeth like normal people! You know, with the bleach under the kitchen sink.
(Don't actually do this)
Toxicologist, toxicity, minuscule, fluoridated -- your big doctor words are just trying to trick us!
Before even wondering about the health effects, we should ask ourselves whether it actually achieves the desired goal. I doubt that.
If it doesn't, we don't even need to wonder about safety; we'll just stop burning money.
