Objective:

To address allegations regarding the integrity of researchers and the validity of fluoride toxicity discussions.

Approach:
  • Review of Previous Work: A systematic examination of fluoride's potential adverse effects was conducted, concluding that fluoride exposure at typical European levels does not support developmental neurotoxicity.
  • Response to Allegations: The authors respond to claims made by Neurath (2025) that question their integrity without evidence, specifically addressing false allegations regarding funding sources.
  • Assessment of Regulatory Bodies: The article discusses findings from the European Food Safety Authority and the German Federal Institute for Risk Assessment, which support the authors' conclusions.
Key Findings:
  • No convincing evidence that fluoride acts as a developmental neurotoxicant at relevant exposure levels in Europe.
  • Allegations against the authors regarding industry influence are false and unsupported.
Interpretation:

Factual accuracy in scientific discourse is crucial, and false claims can undermine trust in research.

Limitations:
  • The article does not address the broader implications of fluoride exposure beyond neurodevelopment.
Conclusion:

Fluoride toxicity remains a topic for scientific investigation.
