Colorado: Cost and Savings Associated with Community Water Fluoridation

A study released in 2001 by the Centers for Disease Control and Prevention (CDC) showes a reduction in tooth decay associated with water fluoridation resulted in substantial cost savings. ColoradoSPH professor Joan O’Connell and coauthors developed a model to update this study using recent information on fluoridation costs, the frequency of tooth decays, and treatment costs.

According to the CDC, in 2013 more than 211 million US residents had access to fluoridated water. O’Connell and her colleagues estimated the cost to fluoridate the water was $324 million, with savings due to reductions in tooth decay of $6.469 billion – meaning the estimated return on investment, 20.0.
