Japan: No Fluoride & No Cavities

Japan study demolishes the basis for artificial fluoridation programs in the US by proving fluoride isn't essential for decay-free teeth. Fluoridation has been exported to other countries without being fully vetted by receiving nations. Everyone trusted the "other guy" to do the research.

"Japan experienced a near-continuous decline in caries among 12-year-olds over approximately 40 years, reaching a national mean DMFT [tooth decay rate] of 0.53 in 2023 - well below levels historically reported in populations exposed to systemic fluoride through community water fluoridation. This decline occurred without community water fluoridation [or any effective personal fluoride use]...Although sugar availability declined early, caries levels continued to fall long after sugar intake stabilized," according to ""A 40-year decline in permanent tooth caries among 12-year-olds in Japan in the absence of systemic fluoride-based prevention: public health implications"
This reflects the cumulative and synergistic effects of multiple modest changes in diet, early-life environments, health-system accessibility, and broader social conditions and represents a large-scale natural social experiment that highlights the additional pathways through which population-level gains can be achieved. “This analysis highlights insight that have long remained unrecognized – not because the evidence was unavailable, but because prevailing frameworks shaped what researchers expected to see”
