The “Catfish study” in Cumbria, UK.

Credit: National Institute for Health Research Fluoridation of the water supply may confer a modest benefit to the dental health of children, a seven-year-study led by University of Manchester researchers has concluded. However, the benefits are smaller than shown in previous studies—carried out 50 years ago—when fluoride toothpaste was less widely available in the U.K. […]

Water fluoridation not enough to shrink dental health inequalities, study finds.

Water fluoridation provides a modest benefit for children’s teeth in an era of fluoride toothpastes, but does not shrink inequalities in dental health between rich and poor communities, research has revealed. Fluoride, a naturally occurring mineral, has been added to drinking water for decades in areas where natural levels are low in a bid to […]

Fluoride in water is of limited benefit because improvements in toothpastes have reduced the positive effects, study suggests.

Adding fluoride to water supplies delivers only a modest benefit to the dental health of children, a new study suggests. The mineral strengthens tooth enamel but, due to improvements in toothpastes over the past 50 years, the boost to oral health of adding it to water has been largely reduced, the study by Manchester and […]

Water fluoridation – is it good or bad?

Note from Fluoride Action Network: • We label this article as misinformation as it states that fluoridation is safe. No mention is made of the 76 (count them!) fluoride IQ studies. Nor is any mention made of the Mother-Offspring fluoride studies. These studies provide compelling evidence that fluoride exposure during the prenatal and postnatal stages […]

Water fluoridation in Scotland?

On 23 September 2021, the four UK Chief Medical Officers (CMOs) stated ‘there is strong scientific evidence that water fluoridation is an effective public health intervention for reducing the prevalence of tooth decay and improving dental health equality across the UK’.1 Water fluoridation started in the USA in 1945 and is currently practised in about […]

Dental health concerns for Gainsborough residents as flouride will no longer be added to water

More than 250,000 Lincolnshire residents will not have any fluoride added to their water for a year, prompting health concerns. Fluoride prevents tooth decay and improves dental health, and is added to the water supply of western Lincolnshire. This is expected to impact on the dental health of people in Lincoln, Gainsborough, Sleaford and Grantham […]
