The British Fluoridation Society (BFS) has welcomed a major new independent review from the Academy of Medical Sciences, reaffirming that community water fluoridation in the UK continues to deliver clear oral health benefits without evidence of harm.
Commissioned by the Chief Medical Officer for England, the review titled ‘Evidence synthesis report on the optimal concentration of water fluoridation in the UK’, is the most comprehensive and up-to-date assessment of the benefits, risks and uncertainties associated with water fluoridation.
The Academy concludes that fluoridation at current UK target levels reduces tooth decay in both children and adults and lowers the need for invasive dental treatment, including hospital admissions for child tooth extractions. These benefits persist despite widespread use of fluoride toothpaste and improvements in oral hygiene.
Crucially, the review finds no evidence that water fluoridation at UK concentrations adversely affects neurodevelopment, intelligence or other non-dental health outcomes.
Studies suggesting possible harms relate to fluoride levels far above those used in the UK and are considered of limited relevance to regulated schemes.
On dental fluorosis, the Academy notes that mild fluorosis can occur but is primarily cosmetic and not harmful at UK fluoride concentrations.

Overall, the report confirms that fluoridation decisions appropriately balance maximising oral health benefits with minimising unwanted effects, within established safety limits.
The review also concludes that community water fluoridation remains a cost-effective public health measure with continued public support across the UK.
BFS says the findings provide timely reassurance for policymakers, dental professionals and the public, and should inform decisions on maintaining and expanding fluoridation schemes in England.
Barry Cockcroft, Chair of the British Fluoridation Society, said: “Once again, water fluoridation receives a clean bill of health from a leading independent expert body. This latest review reinforces fluoridation’s role as a proven and effective foundation for improving oral health inequalities across the UK.”
