Water Fluoridation

After 50 years’ experience of water fluoridation in the UK and nearly 70 years’ experience in the United States, there have been no credible scientific studies to indicate that water fluoridation has caused harm to health.

There have been a number of authoritative reviews of water fluoridation undertaken since the first schemes in 1945.  These contain scientific opinion on both the effectiveness and safety of water fluoridation, reviews undertaken in the past five years are:

You can find the following commentaries that have been published in response to the Cochrane systematic review on water fluoridation in the links below.

The common finding of the reviews looking at dental health is that levels of tooth decay are lower in fluoridated areas and, for reviews which looked at general health effects, that there is no credible scientific evidence that water fluoridation is harmful to health.

The Public Health England report, ‘Water Fluoridation Health Monitoring for England (2014)’ compared a range of dental and non-dental health indicators in fluoridated and non-fluoridated areas in England and can be viewed at: https://www.gov.uk/government/publications/water-fluoridation-health-monitoring-report-for-england-2014
