bullshit. look up weston a. price. wild homo sapiens, i.e., humans living outside of domesticated realm, have perfect teeth. they don't brush. they don't floss. they don't ingest fluoride.  it's their diet. domesticated humans have terrible teeth because of their non-evolutionary diets.  the fluoride used in water supplies or toothpaste is a different form from the naturally occurring fluoride found in various areas around the world. it's industrial fluoride, crap left over from aluminum processing.  the greedy owners of those aluminum companies went out and rebranded it as healthy for teeth. it only helps to a certain extent. if your diet is domesticated shit tier, the fluoride will help a little, but your teeth are still being damaged. look at all the folks who do their best to take care of their teeth but still wind up in the dentist's chair to get fillings or root canals. it's our diets. fluoride only does so much.
