Fluoride has quietly protected Australian families for decades. It strengthens enamel, reduces decay, and lowers the risk of dental emergencies. But with some councils across the country choosing to remove fluoride from water supplies, health experts are warning that communities may face a serious rise in preventable dental problems.

Before this becomes a wider issue, it is worth understanding what fluoride does, why it matters, and what could happen if fluoride were ever removed from tap water in areas like Maroubra.

What could happen if fluoride were removed from tap water?

Research from Australia and overseas shows one clear pattern: when fluoride is taken out of a water supply, dental decay increases… quickly.

Communities that have removed fluoride have seen:

• Higher rates of childhood cavities
  • More dental abscesses requiring urgent care
  • Increased hospitalisations for severe decay
  • Rising treatment costs for families
  • Faster enamel breakdown caused by everyday acids

These changes have been documented within just a few years of fluoride removal.

When reporting on the recent Queensland decisions, University of Queensland dental expert Dr Michael Foley issued a strong warning in the ABC’s coverage, stating, “Water fluoridation is one of the no-brainers in public health. It saves vastly more money in dental treatment costs than what it costs to implement.”

In simple terms, fluoride protects the teeth of every household, every day, without you needing to do anything extra. Losing it means families must work significantly harder to achieve the same level of protection.

Why fluoride matters for Maroubra families

Even in areas with excellent dental services, fluoride remains one of the most effective ways to prevent cavities. Children and teenagers benefit the most because their enamel is still developing, but adults see long-term protection as well.

Without fluoride in the water, families in Maroubra would face:

• More frequent dental visits
• A higher risk of ongoing decay
•  Greater chance of toothaches and infections
• Increased likelihood of needing fillings, root canals, or extractions

These are preventable outcomes. Fluoride is not a luxury. It is a baseline protection that reduces everyday wear and shields enamel from the acids in food and drink.

If your home does not receive fluoridated water, your risk is already higher

Households using rainwater tanks, bottled water or certain filtration systems may be missing out on fluoride without realising it. The ABC notes that many Australians are unsure whether their local water supply contains fluoride at all. When fluoride exposure is low, teeth are more vulnerable to everyday acids and bacteria, which increases the risk of decay across all ages.

If your home has limited or no fluoride, strengthening your approach to preventative dentistry becomes even more important. This may include:

• Brushing twice daily with a fluoride toothpaste
• Not rinsing immediately after brushing
• Reducing sugary and acidic drinks
• Using fluoride mouthrinses if advised
• Scheduling regular dental check-ups
• Considering professional fluoride varnish treatments

Preventative dentistry treatments provided at our Maroubra clinic, such as fluoride varnishes and routine examinations, play a key role in reducing decay risk when fluoride levels are low.

Professional fluoride treatments: your safety net if water fluoride ever falls

Dentists can apply concentrated fluoride varnish to reinforce enamel, strengthen weakened spots, and protect teeth between visits. If fluoride levels in tap water were ever reduced or removed, professional fluoride treatments would become even more important for families who want to avoid unnecessary dental issues.

The bottom line

Fluoride in drinking water is one of the simplest forms of protection we have. When it is removed, decay rises, dental costs increase, and children are affected the most.

For Maroubra families, access to fluoride means healthier teeth, fewer dental emergencies, and better long-term oral health.

If fluoride were ever removed from the water supply, the impact would be felt quickly. The good news is that preventative care, fluoride toothpaste, and regular dental check-ups can help protect your teeth even if water fluoride levels change.
