What Happened & Why
As of July 1, 2025, Florida officially became the second state in the U.S.—after Utah—to prohibit the addition of fluoride to public drinking water systems. The measure, passed as part of the state’s sweeping agriculture bill (SB 700), blocks municipalities from supplementing drinking water with fluoride or other additives. Governor Ron DeSantis, backed by Florida Surgeon General Joseph Ladapo and newly appointed Health and Human Services Secretary Robert F. Kennedy Jr., justified the decision on the grounds of personal liberty and medical autonomy.
Supporters of the ban argue that water fluoridation amounts to “forced medication” and that individuals should be allowed to choose whether to consume fluoride—via toothpaste, supplements, or diet. This law impacts approximately 97 water providers across 27 counties who had previously fluoridated their water systems. Some areas, such as Duval County, already have naturally occurring fluoride levels close to CDC recommendations (~0.7 ppm), and will not be affected in practice. Others, like Orange County, fall well below the optimal level. The decision has reignited a national debate about the role of public health policy versus individual choice.
The Scope of the Ban
- The law blocks local authorities from supplementing naturally occurring fluoride in community water systems. About 97 water providers across 27 counties must cease fluoridation.
- Natural fluoride remains in groundwater; for example, Orange County’s levels (~0.14 ppm) exceed the CDC-recommended 0.7 ppm.
- Duval County, with naturally optimal fluoride levels (~0.7 ppm), will continue without change.
Reactions: Health Warnings vs. Personal Choice
The fluoride ban has received mixed reactions from public health experts, dental associations, and political figures. The Florida Dental Association, American Dental Association (ADA), and Centers for Disease Control and Prevention (CDC) have all criticized the move, warning that eliminating fluoride from public water systems could reverse decades of dental health progress. They argue that fluoridation is one of the most cost-effective ways to prevent tooth decay, especially in children and low-income populations with limited access to dental care.
On the other hand, proponents of the ban—including certain conservative lawmakers and anti-fluoride activists—maintain that individuals should not be subjected to medical treatments through their tap water. Citing studies that suggest potential links between high fluoride exposure and neurological issues like reduced IQ or ADHD, these advocates are pushing for a more personalized approach to fluoride consumption.
Public health experts point to historical data from other countries and municipalities where fluoride was removed, which consistently shows an uptick in dental decay following removal. While the science on fluoride’s risks remains debated, the consensus among major health organizations is clear: community water fluoridation is safe, effective, and significantly beneficial—particularly for vulnerable populations. Fluoride or not, drinking clean, filtered water is important for health and hydration.
What This Means for You
- Dental caution: Without community-level fluoride protection, children and the elderly — particularly in underserved areas — may face higher cavity risk.
- Alternative fluoride sources: Use fluoridated toothpaste, mouthwash, or supplements. Consult your dentist for appropriate use.
- Consider filtration: For families concerned about either exposure or deficiency, filtered water or other clean sources may help.
- Stay informed locally: Check your county’s water quality reports—some may still have natural fluoride, while others might drop below optimal levels. If you’d like an accurate look at what contaminants are in your water, use our free water report tool.
Final Takeaway
Florida’s fluoride ban reflects a growing emphasis on personal choice and autonomy. But it also challenges proven public health tools—especially for vulnerable communities. Staying informed, prioritizing preventive care, and collaborating with dental professionals will help Floridians ensure strong oral health in the fluoride-free era.
