Indiana is 95% fluoridated:
"According to Dr. Smith, the number of dentists in Indiana has not kept pace with the growing population. From 1990 to 2006, the number of practicing dentists in the state increased by only three dentists, while the population of Indiana increased by more than 725,000. Dr. Smith says, consequently, tooth decay is the most common chronic childhood disease in Indiana. The Marion County Health Department funded a 2004 Indiana University Oral Health Research survey that reported 48 percent of six- to eight-year-old children had untreated dental decay."
