Gainesville, Florida, where the Florida School of Dentistry is located, is fluoridated since 1949:
"Dr. Daniela Rodrigues Silva, an assistant professor of pediatric dentistry at the University of Florida's School of Dentistry, says her experience in treating young patients bears out those numbers. 'Unfortunately, we've seen a humongous increase in cavities among those young patients at our clinic,' Silva says.
She cites the case of a 4-year-old girl she recently encountered while screening children for a Head Start program. Silva found cavities in all 20 of the girl's primary teeth."
