A recent surge in debate surrounding fluoride in drinking water has sparked concerns among healthcare professionals. This letter, penned by a dental hygienist with over four decades of experience, argues strongly against the removal of fluoride, highlighting its proven benefits in preventing tooth decay, particularly within vulnerable demographics. Removing this vital public health measure could lead to a significant increase in dental disease and place an unnecessary burden on our healthcare system.

For decades, fluoridation has been a cornerstone of preventative dental care in many countries, including Ireland. The science is clear: fluoride, when present in appropriate concentrations in drinking water, strengthens tooth enamel, making it more resistant to acid attacks from bacteria and sugars. This is particularly crucial for children, whose teeth are still developing, and for individuals with limited access to dental care.

The argument for removing fluoride often centres on concerns about potential health risks. However, these concerns are largely unfounded and based on misinformation. Extensive research, conducted over many years by reputable scientific organisations like the World Health Organization (WHO) and the Irish Dental Health Foundation, has consistently demonstrated that water fluoridation at recommended levels is safe and effective. The levels used in Ireland are carefully controlled to ensure maximum benefit with minimal risk.

Consider the impact on our children. Tooth decay is a significant public health problem, especially among children from disadvantaged backgrounds. Fluoridated water provides a simple, cost-effective way to reduce the prevalence of cavities and improve overall oral health. Removing this protection would disproportionately affect those who need it most, exacerbating existing health inequalities.

Furthermore, the cost of treating dental disease is substantial. Removing fluoride would likely lead to an increase in the demand for dental services, putting additional strain on an already stretched healthcare system. Prevention is always better – and cheaper – than cure.

The claim that individuals can simply avoid drinking tap water is unrealistic for many. Tap water is often used for cooking and preparing food, and many people rely on it as their primary source of hydration. Expecting everyone to consistently use bottled water is impractical and environmentally unsustainable.

As a dental professional who has dedicated their career to promoting oral health, I urge policymakers to carefully consider the potential consequences of removing fluoride from our water supply. It would be a step backward in public health, jeopardizing the well-being of countless individuals, particularly our children. Let's not sacrifice a proven public health benefit based on unfounded fears and misinformation. Maintaining fluoridation is an investment in a healthier future for all Irish citizens.
