Here’s a list of the most convincing studies or meta analyses.
2023 – NTP Monograph on Fluoride Neurotoxicity – National Toxicology Program (USA)
2020 – Till et al. – Infant Formula Fluoride Exposure & IQ – Till C, Green R, Lanphear B, Hornung R, Martinez-Mier EA (Canada)
2019 – Green et al. – Maternal Fluoride Exposure & IQ – Green R, Lanphear B, Hornung R, Flora D, Martinez-Mier EA, et al. (Canada)
2017 – Bashash et al. – Prenatal Fluoride Exposure & Offspring IQ – Bashash M, Thomas D, Hu H, et al. (Mexico/USA)
2012 – Choi et al. – Meta-analysis on Fluoride & Neurodevelopment – Choi AL, Sun G, Zhang Y, Grandjean P (Harvard/China)
2006 – NRC Report – Fluoride in Drinking Water – National Research Council (USA)

How did you compile this list? Asking some LLM service?
From the first link:
> It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ
It doesn't seem in favor of this?
Regardless of where they got the list (edit: which I do think is a fair question)...
> the first link [...] doesn't seem in favor of this?
To me that falls under "the best evidence [available] in favor of this." It's not great, but it's not nothing; it's certainly something in favor. After all.. I guess I don't know about you, but I feel like if someone told me dose X of something is toxic, I would not feel comfortable feeding myself and the entire country 50% of that dose, on that basis alone.
I mean, technically our atmosphere gives us oxygen at 35% of a toxic dose/concentration.
Granted, 35% < 50%, but not really that much less.

Why does it matter how the list was compiled? Is the information accurate or not? The first link you referenced with the cherry picked sentence about uncertainty for levels below .7mg/l was a meta analysis of 74 different studies, 64 of which showed a negative correlation between child IQ and fluoridation. This isn’t even taking into account evidence of a positive correlation for early onset puberty, sleep disruption and bone cancer with fluoridation.
It matters because your statement of "Here’s a list of the most convincing studies or meta analyses." assumes some kind of curating. If all you're doing is providing something akin to a google search, it's not really valuable.

It matters when you say it has the "most convincing" evidence as if you have read them all and are keeping up with the field and didn't just summarize them with some service like https://consensus.app/
I don't know if what you are repeating is slop, etc. I can't trust the source.
A single recent systematic review is more trustworthy than that.
