Scientific Research into Fluoridation

There have been many studies on water fluoridation and its effects. The evidence strongly suggests that water fluoridation is not safe or effective.

Over 400 studies have now shown fluoride to be damaging to the brain and 61 studies have shown fluoride to reduce IQ in humans (FAN, 2019).

Here are a few of the most relevant and significant studies:

Association Between Maternal Fluoride Exposure During Pregnancy and IQ Scores in Offspring in Canada (Green R, Lanphear B, Hornung R, et al. 2019) –https://jamanetwork.com/journals/jamapediatrics/fullarticle/2748634

Prenatal Fluoride Exposure and Cognitive Outcomes in Children at 4 and 6-12 Years of Age in Mexico (Bashash, M. et al. 2017) –  https://www.ncbi.nlm.nih.gov/pubmed/28937959

A Complete Waste of Money! Water Fluoridation Costs for England, 2013-2021 (Warren, J. A. and Pain, G. 2017) – https://www.researchgate.net/publication/319460176_A_Complete_Waste_of_Money_Water_Fluoridation_Costs_for_England_2013-2021

Are fluoride levels in drinking water associated with hypothyroidism prevalence in England? A large observational study of GP practice data and fluoride levels in drinking water (Peckham, S., Lowery, D. and Spencer, S. 2015) – http://jech.bmj.com/content/69/7/619 

Water Fluoridation: A Critical Review of the Physiological Effects of Ingested Fluoride as a Public Health Intervention (Peckham, S. and Awofeso, N. 2014) – https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3956646/

Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis (A. L. Choi, et al2012) – https://ehp.niehs.nih.gov/1104912/

Systematic Review of Water Fluoridation (McDonagh, et al. 2010) – http://www.bmj.com/content/321/7265/855

The above review by McDonagh, et al. has been often misrepresented and used to promote fluoridation. Please also read this letter from Professor Trevor Sheldon, the chair of the advisory group for this review:  https://www.nofluoride.com/york_report_chairman.cfm
