The environmental impact of water fluoridation

Researchers from Trinity College Dublin collaborated with University College London on a new study on the low environmental footprint of water fluoridation compared to other preventive measures for tooth decay.

Water fluoridation is one of the most significant interventions in public health during the twentieth century. But, as the climate continues to change, considerations must be made on the contribution of healthcare and disease prevention.

Researchers considered the environmental impact of water fluoridation for an individual five-year-old child over a year. This data was then compared to the traditional use of fluoride varnish and toothbrushing programmes taking place across schools in the UK and internationally.
