After 9 years and $3 million of adding fluoride, research shows tooth decay hasn’t dropped among the poorest of Bexar County’s children. It has only increased—up 13% in 2010, the latest date that data was available.

One out of two children in the Head Start program who were checked for cavities had some decay last year.

Despite country-wide fluoridation, "half of all 12-year-olds in Ireland and three-quarters of 15-year-olds already have tooth decay and a love of high-sugar food and drinks appears to be the main culprit, dentists have warned."

North Carolina is 88% fluoridated. Yet, "63 percent of children begin their school career in poor oral health. That means in the average kindergarten classroom about 13 children suffer from decayed, filled or missing primary teeth. But this number represents an average; when we dig deeper into the data, stark geographic disparities emerge which suggest some communities lack access the resources needed to protect their children's oral health."
