Americans enjoyed savings of $32 per capita in tooth decay prevention, according to a national assessment of fluoridation by Colorado School of Public Health (ColoradoSPH) researchers published in Health Affairs.
The work updates a 2001 comprehensive study of U.S. community water fluoridation program costs and benefits. Joan O’Connell, PhD, associate professor in the Community & Behavioral Health Department of the ColoradoSPH at CU Anschutz, and coauthors developed a model to update that national study using more recent information on fluoridation costs, the incidence of tooth decay and treatment costs.
Researchers found that in 2013 more than 211 million people had access to fluoridated water through community water systems serving 1,000 or more people. They estimated 2013 savings associated with caries averted as a result of fluoridation to be $6.8 billion, or $32 per capita. The estimated cost to community water fluoridation programs providing fluoridation was $324 million, with net savings estimated at $6.5 billion and a $20 return on investment for each $1 spent. Estimates of per capita savings associated with community water fluoridation may be used by states to estimate net savings and a return on investment using local data on fluoridation costs.
