Fluoride rate limits muscle production in men. Makes us more manageable by authority. Also makes the elderly decline much faster after the age of 70s so they don't become a drain on the economy.
Dysregulates Melatonin production to achieve this. Sleep disturbance and faster rate of muscle loss / harder to put muscle on is the ultimate result.
As for all the insane conspiracy theories spread around it, you'll notice it's the same tactic as the sugar, cigarette, and fossil fuel industry.
When they do something atrocious, they flood the space and muddy the waters. Discredits anyone who investigates by default and delays action.
Governments, themselves, spread all those insane conspiracy theories.
Harvard Department of Environmental Health worked this out long ago, as have many research universities. All the studies are there. It's just that the waters are so muddied, the gaslighting laid on so thick, no one acts on it.
If you want to use the heath of teeth as an excuse for adding fluoride to the water, then you need to maintain poor oral health in the population to justify it.
Meanwhile, we've developed multiple techniques to prevent plaque and caries, we've developed multiple techniques to regenerate caries, and we can even regrow teeth by suppressing the JAK / Stat signalling pathways in mammals, so we can grow new teeth endlessly like other species.
Not that you'll hear any of this.
