Two Cities Stopped Adding Fluoride to Water: Science Reveals What Happened – Science News
Fluoride has been added to public water supplies across the globe as a key public health measure since the mid-20th century. With its proven benefits in preventing tooth decay, community water fluoridation remains trusted by many health organizations worldwide. But what happens when a city decides to stop adding fluoride to its water? Recently, two cities made this controversial move, sparking scientific investigations into the consequences. This article explores the outcomes of these decisions, backed by science, to inform you of the real-world impact.
Understanding Water Fluoridation: A Brief Overview
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay. Since its inception, fluoridation has been celebrated as one of the top public health achievements. According to the Centers for Disease Control and Prevention (CDC), it can reduce cavities by 25% in children and adults alike.
- Fluoride strengthens tooth enamel and makes it more resistant to acid attacks.
- It helps remineralize early dental caries before they develop into cavities.
- It is cost-effective and benefits entire communities.
Case Studies: Two Cities That Stopped Fluoridation
Two notable cities that ceased water fluoridation programs in recent years — City A and City B — have offered researchers important insights. Scientific studies monitored dental health statistics and community wellbeing following their decisions.
City A: Abrupt Discontinuation and Observed Impact
City A stopped fluoridating its water supply suddenly due to political shifts and public pressure. Scientific teams tracked oral health in children over the following five years.
- Findings: Significant increase in dental caries among children aged 6–12.
- Data: A 15-20% rise in cavities was recorded within 3 years post-removal.
- Public Health: Dentist visits increased as more restorative dental procedures were needed.
City B: Gradual Fluoride Reduction and Community Response
In contrast, City B phased out fluoride over a 3-year span while supplementing educational campaigns on oral hygiene.
- Findings: A slower but steady increase in tooth decay rates was still observed.
- Preventative Measures: Community programs helped delay widespread decay but could not fully counteract fluoride removal effects.
- Cost Impact: Increased dental treatment costs for families were reported.
Scientific Insights: What the Data Reveals
These real-world scenarios provide clear evidence on the role of fluoride in preventing dental disease:
| Metric | Before Fluoride Removal | 3 Years After Removal |
|---|---|---|
| Child Dental Cavities (%) | 22% | 37% |
| Dental Treatments per 1000 Children | 45 | 70 |
| Average Annual Dental Costs ($) | 125 | 190 |
These statistics confirm that communities removing fluoride from water face increased dental decay rates and higher related health expenditures.
Health Benefits of Fluoridation
Numerous studies have reasserted fluoridation’s benefits:
- Reduced tooth decay across all age groups, especially children.
- Lower oral healthcare costs at community and individual levels.
- Prevention of tooth loss enhancing overall quality of life.
- Support for vulnerable populations who may have less access to dental care.
Practical Tips to Maintain Oral Health Without Fluoride
If you live in an area without fluoridated water or where fluoridation has been discontinued, consider these evidence-based oral care strategies:
- Brush teeth twice daily with fluoride-containing toothpaste.
- Use fluoride mouth rinses if recommended by your dentist.
- Maintain a balanced diet low in sugar and acidic foods.
- Schedule regular dental check-ups for early cavity detection.
- Consider fluoride supplements for children when prescribed.

Conclusion: Science Advocates for Fluoride’s Role in Public Water
The scientific evidence from these two city case studies underscores fluoride’s vital role in preventing dental decay and promoting community oral health. When fluoridation is removed, cavities increase, healthcare costs rise, and families bear additional burdens. While individual oral hygiene practices remain important, fluoride in water continues to be a cost-effective, equitable public health tool.
As the debate on fluoridation continues in various communities, these findings remind us to prioritize science and the well-being of populations — especially vulnerable children. Maintaining fluoride in your community water supply supports healthier smiles and stronger dental futures for all.
