Not to mention there are many natural sources of fluoride which can contain greater concentrations of it than what is in tap water. The ocean has a concentration of fluoride that is in the range of 1.2 to 1.4 ppm, compared to the standard rate of fluoride of drinking water, which is 0.5–1 ppm

edit: I didn't say that people drink ocean water, my point was about the ubiquitous nature of fluoride. The majority of life lives in the ocean, so if fluoride really was as toxic as some people say it is, there would be a lot less life on Earth. There are many lakes and other water sources that people have been drinking from for ages which naturally contain higher amounts of fluoride than what is in fluoridated tap water.

I don't understand your point.

Nobody drinks the ocean. Fluoride is barely active topically. Most humans rarely if at all swim in the ocean.

From what I have read, fluoride’s action on teeth is purely topical. Which is why it is in toothpaste (which is not swallowed). The “minuscule” amount in drinking water is reported as not enough to be toxic, yet somehow enough to strengthen teeth through internal blood circulation. Any fluoride you ingest, even a few atoms, is considered a toxin by the body and removed. So while the minuscule amounts added to water may not harm you, they are still adding to the “workload” your body has in dealing with all the minuscule amounts of other toxins you acquire daily.
