Omg, no wonder my teeth are getting worse after moving to Amsterdam. I drink a ton of water and use Maldon salt. I didn’t realize there wasn’t fluoride in the water. (All the Nutella isn’t helping either, but… ooh, maybe that’s a reasonable vector for Europeans)
Authorities making recommendations about minutiae does not really dictate much of the way I live my life. If they want to make it a law, fine, I'll brush my teeth in between the cups of coffee I serially drink from the moment I rise until roughly dinnertime when I then switch to alcohol (something strongly discommended by other authorities). My teeth are fine, 40 years and counting. Perhaps it's all a conspiracy by Big Toothpaste to sell more toothpaste.
