Fluoride Myths Moms Hear (and the Facts)

• Myth: “Kids shouldn’t use fluoride.”  Fact: When used as directed, fluoride is safe and effective at reducing cavities.
• Myth: “More toothpaste is better.”  Fact: Use smear (<3) or pea‑size (3–6+). More isn’t better and may raise fluorosis risk if swallowed.
• Myth: “Bottled water protects teeth like tap.”  Fact: Many bottled waters have little or no fluoride. Optimally fluoridated tap water is protective.

FAQ

1. Can too much fluoride damage my child’s teeth?
Too much fluoride over a long period can cause mild fluorosis (tiny white spots on teeth), but this is extremely rare. When fluoride is used under a dentist’s guidance, it’s completely safe and beneficial.

2. Is bottled water better because it doesn’t have fluoride?
Not really — bottled water often lacks the fluoride that helps protect teeth. Kids who drink mostly bottled water may actually have a higher risk of cavities compared to those who drink fluoridated tap water.

3. Are natural or “fluoride-free” toothpastes just as effective?
While they may sound appealing, fluoride-free toothpastes don’t protect against cavities the way fluoride ones do. For most children, a pea-sized amount of fluoride toothpaste is the best defense for strong, healthy smiles.
