Oh, absolutely. I don't know where fluoride is sourced from, but it wouldn't surprise me to learn it's an industrial byproduct that would otherwise have to be disposed of as toxic waste.
And anybody who wants to reflexively defend fluoridation because of the political bias of its American opponents should note water fluoridation is literally illegal in developed countries:
Fluoridation of community drinking water is considered unethical because individuals are not being asked for their informed consent prior to medication. It is standard practice to obtain consent for all medication, and this is one of the key reasons why most of Western Europe has ruled against fluoridation. It is a violation of human rights, a direct violation of the Nuremberg code that states that research or even routine medical procedures must be done with the voluntary cooperation of the subjects who must be fully informed of the risks or benefits of the procedure in which they are involved.
