while ignoring bodies of scientific evidence contradicting your viewpoint

They have viewpoints on topical application of fluoride and lack of effect on teeth after swallowing.

What bodies of evidence are contradicting these opinions?

The latest studies indicate fluoride in the drinking supply has little effect compared compared to fluoride toothpaste. So you once it is available the need for adding fluoride to water goes away. This has been supported by numerous studies comparing countries that do not add fluoride to their water.

I studied this in a 400 level water course at UNI. I got to visit wastewater and water plants and speak with operators. I was surprised to learn the fluoride was not naturally occuring in the water supply as it is advertised on the EPA website.

Then I found an article about a small town in Canada that ran out of fluoride because of a downturn in fertilizer manufacturing. I thought to myself what does fertilizer manufacturing have to do with fluoride.

That is when I discovered the truth that a toxic by-product of fertilizer manufacturing is sold to municipalities to be disposed of in our water supply. It is not pharmeucutical fluoride because that would cost too much. Oh and it is contaminated with nasty stuff like heavy metals.

I then did a bunch of research comparing rates of tooth decay in different areas of the world. It really did not appear to make a difference but actual dental care and fluoride toothpaste did.

My presentation was about a hour and a half where I presented all my research. I got an A on it and everyone was very impressed with what I discovered.

But sure tell me about my own journey when you literally have no fucking clue what you are talking about about.
