Fluoride Bans Could Cost Medicaid $40M
19 Mar
Summary
- Five states banning fluoride could cost Medicaid over $40 million in three years.
- An additional 132,572 children may need cavity fillings or tooth extractions.
- Water fluoridation is an evidence-based public health achievement reducing tooth decay.

A new analysis suggests that if five states ban fluoride from drinking water, Medicaid could face over $40 million in costs within three years due to a surge in childhood cavities. The projected increase in dental care needs for children could reach 132,572 additional cases requiring cavity fillings or tooth extractions.
This situation is particularly concerning as Florida has already banned community water fluoridation, and other states like Kentucky, Louisiana, Missouri, and Oklahoma are considering similar legislation or making it optional. Experts emphasize that water fluoridation is a highly effective, widely accessible tool for preventing tooth decay, credited by the CDC as a major public health achievement.
While fluoride has faced some opposition, dental experts generally support its use, noting that optimal levels are carefully controlled. Concerns about potential neurological impacts or associations with lower IQ scores in children have been raised, but often based on studies with significantly higher fluoride concentrations than those used in U.S. water systems.
