Existing drinking water fluoridation programmes in England still provide marginal savings for the NHS, but there is no guarantee new schemes would continue to do so, a study led by University of Manchester researchers finds.

It is the largest-ever study of the effects of water fluoridation on the dental health of adults.

The National Institute for Health and Care Research funded a data study of 6.4m UK adults and adolescents across England and published in Community Dentistry and Oral Epidemiology estimated the public sector saved £16.9m between 2010 and 2020 due to water fluoridation.

People receiving optimally fluoridated water in the study experienced a three per cent reduction in NHS invasive dental treatments such as fillings and extractions, and a two per cent reduction in the numbers decayed, missing, and filled teeth, when compared to the non-optimally fluoridated cohort over 10 years.
