America is a fluoride fanatic. The UK adds it to about 10% of their water. Canada goes full force with 0.7 too, like a polite neighbor.
But many European countries say "no thanks" to water fluoridation. They rely on fluoride toothpaste and salt instead. The Netherlands is all about the salt, because they love a good seasoning.
Here’s a head-scratcher: in Sweden, they don’t fluoridate water at all. Yet their cavity rates are lower than the U.S. How? They eat less sugar. It’s the real magic trick.
10 Reasons Why Fluoride Is In The Tap Water We Drink - Water
The "Too Much" Panic Button
Don’t panic. You’d need to drink over 50 liters of tap water daily to reach toxic levels. That’s like a bathtub every morning.
But there’s a condition called fluorosis. It’s when kids swallow toothpaste or drink tons of fluoridated water while their teeth are still forming. The result? Tiny white streaks or spots—like tiny stars on your teeth.
It’s harmless and barely visible. But it’s a great excuse to say, "My teeth are fluorescent" at parties. No one will fact-check you.
