Fluoride 101: What It Is, Why It Works

• How it protects: Fluoride helps remineralize weak spots and lowers bacterial acid activity.
• Where kids get it: fluoride toothpaste, varnish at the dentist, and optimally fluoridated water (0.7 ppm).
• At home: smear under 3; pea‑size 3–6+; brush 2×/day; avoid vigorous rinsing after brushing.
• Higher‑risk kids: may benefit from professional varnish 2×/year or more often as advised.
• Supplements: Only if water is not fluoridated and your dentist recommends it after reviewing all sources.
