Overview
- New guidance advises against fluoride tablets or drops in children under three and in older children at low or moderate cavity risk, reserving use for high‑risk kids or those with minimal fluoride exposure.
- The FDA sent warning letters to manufacturers telling them not to promote ingestible fluoride products for young children.
- An FDA review points to tooth staining and emerging concerns involving the gut microbiome as well as possible neurocognitive and gastrointestinal effects, while emphasizing that research is still developing.
- The American Dental Association continues to back targeted prescriptions for high‑risk children who lack adequate fluoride in drinking water, saying the FDA’s stance largely aligns with existing dental guidance.
- Most people on public water systems receive fluoridated water, yet new state bans in Utah and Florida are reducing coverage as federal officials re‑evaluate national fluoridation recommendations.
