The argument in the past was that with toothpaste you at least have a choice since there's flouride-free brands. With tap water you don't have that choice. You end up with whatever % they choose and how much you consume. There's never a definitive level.
Also, you're supposed to spit out toothpaste, not swallow it. Fluoride in tap water means its in your ice machine, you make drinks with it, cook with it, shower in it, water plants with it, etc.
What about the toothpaste?

Another thing I wish could be banned is cigarettes.
I haven't used fluoride toothpaste in years. Always use xylitol and baking soda.
Not a single stain on my teeth.
