The US Food and Drug Administration (FDA) is considering removing prescription fluoride tablets from the market, and with several states already banning fluoride in drinking water, parents across the globe, including here in New Zealand, are understandably concerned. Is fluoride harmful? What does the science actually say about its impact on children’s health? This article breaks down the research, explores the debate, and helps you understand what it means for your whānau.

The Changing Landscape of Fluoride

For decades, fluoride has been a cornerstone of public health initiatives aimed at preventing tooth decay. It’s been added to drinking water and available in toothpaste and supplements. However, a growing movement questioning its safety and efficacy has led to increased scrutiny. The FDA's potential move to remove prescription fluoride tablets is a significant development, and it's prompting a re-evaluation of its role in oral health.

What Does the Research Say?

The evidence surrounding fluoride’s benefits and potential risks is complex. Let's look at both sides:

The Benefits: Fighting Tooth Decay

Numerous studies have demonstrated fluoride’s effectiveness in preventing tooth decay. It strengthens tooth enamel, making it more resistant to acid attacks from bacteria in the mouth. For children, who are particularly vulnerable to cavities, fluoride can be a vital tool in maintaining good oral health. Public health organizations like the New Zealand Dental Association (NZDA) generally support fluoridation as a safe and effective way to reduce tooth decay rates, particularly in vulnerable populations.

Potential Risks: Concerns and Controversies

Despite the benefits, concerns about fluoride exposure have been raised. Some argue that excessive fluoride intake can lead to:

• Dental Fluorosis: This condition causes discoloration or mottling of tooth enamel, usually occurring in children whose teeth are developing. Mild fluorosis is common and generally harmless, but severe cases can be more noticeable.
• Skeletal Fluorosis: This is a long-term condition resulting from very high fluoride exposure over many years. It can lead to joint pain and stiffness. This is far less common in areas with controlled fluoridation.
• Neurotoxicity Concerns: Some studies have suggested a possible link between high fluoride exposure and neurodevelopmental issues, although this remains a controversial area of research and requires further investigation.

The FDA's Review and What It Means for You

The FDA's review of prescription fluoride tablets is primarily focused on the changing landscape of oral health products. With widespread access to fluoridated toothpaste and water, the need for prescription tablets may be diminishing. However, the decision has sparked debate about the broader use of fluoride.

Fluoride in New Zealand: A Local Perspective

It’s important to note that New Zealand’s approach to fluoridation differs from the US. Many, but not all, New Zealand communities have fluoridated water supplies. The decision to fluoridate a community is made by local councils, based on public health advice. It's crucial to check whether your local water supply is fluoridated.

Making Informed Decisions

Ultimately, the decision of whether or not to use fluoride supplements for your children is a personal one. Here's what to consider:

• Talk to your dentist: They can assess your child’s individual risk of tooth decay and recommend the best course of action.
• Consider your water supply: If you live in a fluoridated area, your child is already receiving fluoride through their drinking water.
• Be mindful of other sources of fluoride: Toothpaste and mouthwash also contain fluoride.
• Stay informed: Continue to research and stay up-to-date on the latest scientific findings.
