Objective:

To review the history, effectiveness, and current criticisms of fluoride use in dental health, with a specific focus on community water fluoridation and topical applications.

Approach:

Key Findings:

Community water fluoridation significantly reduced dental caries in historical studies, particularly before 1975.
Recent reviews indicate a diminished impact of water fluoridation post-1975 due to the widespread use of fluoridated toothpaste, with specific data on caries reduction.
Fluoride's primary caries-preventive effect is topical rather than systemic, supported by recent laboratory and epidemiological studies.

Interpretation:

While fluoride remains beneficial for dental health, its effectiveness may be more pronounced through topical application, necessitating a reevaluation of community water fluoridation's role, especially for populations with limited access to fluoride products like toothpaste.

Limitations:

Recent studies have raised concerns about fluoride's safety, particularly regarding children's IQ, with insufficient evidence to fully understand the implications.
Insufficient evidence exists to determine the necessity of water fluoridation for lower socioeconomic groups, highlighting the need for further research.

Conclusion:

The necessity of community water fluoridation should be reconsidered in light of the evidence supporting topical fluoride use, particularly as access to fluoridated toothpaste improves.
