Fluoride is like chocolate cake: great in moderation, a disaster in excess. Too much and you get fluorosis, which causes faint white streaks on teeth. It’s not dangerous, but it’s not the glow-up you’re after, either.
Stick to the recommended dosage. For most adults, that’s 0.7 milligrams per liter of water (which sounds fancy but is basically a few drops). If you’re using tablets, check your local tap water’s fluoride level online first—many towns already add it. You don’t want to double up like you’re late for a party.
