RFK Jr. wants to stop putting fluoride in drinking water. Here’s what scientists say
Fluoride is a naturally occurring mineral that is commonly used in dentistry to strengthen tooth enamel and prevent cavities. In many parts of the world, including Canada, fluoride is added to the drinking water supply to help prevent tooth decay in the community. This practice is supported by major public health bodies such as the World Health Organization and the Public Health Agency of Canada.
According to the Public Health Agency of Canada, fluoridation is associated with a 25 per cent reduction in tooth decay in children and adults. In Canada, 38.8 per cent of the population has access to fluoridated water, with access varying across provinces and territories based on factors like cost and infrastructure.
While some have raised concerns about the practice of water fluoridation, many of these concerns are not based on sound scientific evidence. Gerry Uswak, the director of the dental therapy program at the University of Saskatchewan, emphasizes the importance of making policy decisions based on objective scientific data rather than emotion.
Ingesting too much fluoride over a long period of time can lead to skeletal fluorosis, a rare bone disease. However, health authorities in Canada adjust fluoride levels in water to keep it safe and prevent such risks. Another mild risk associated with fluoride consumption is dental fluorosis, which can cause white spots on the teeth but has no other harmful effects.
Recent studies have looked into a possible link between fluoride exposure and intelligence in children. While some studies suggest an association between fluoride exposure and lower IQ scores, the evidence is not conclusive, and other factors may be at play. More research is needed to determine the impact of fluoride on cognitive development.
Overall, water fluoridation remains a cost-effective and equitable way to prevent tooth decay for everyone in the community, especially those who may not have easy access to dental care. It is just one tool among many in ensuring dental health among Canadians. As scientific inquiry continues to evolve, it is essential to base policy decisions on objective and evidence-based research to promote the well-being of the population.
