Here’s where it gets interesting. Some experts say too much fluoride in water can cause those white spots on baby teeth. The American Dental Association suggests using fluoride-free water for mixing formula.
But if your tap water has low fluoride (under 0.7 mg/L), you’re probably fine. You can call your local water company and ask them (they’re usually happy to chat).
If you’re paranoid, just use distilled or boiled tap water. Your baby’s teeth will thank you, and you’ll sleep better at night.
