This bill is important, because dental health, in a way, is such a simple thing. If you enjoy good oral health, you probably take it for granted, but it matters so much to people who struggle with the consequences of dental caries, pain, procedures, and, in some cases, disfigurement. There is unequivocal evidence that fluoridation of drinking water prevents tooth decay. We know that it probably close to halves or reduces by maybe 40 percent the lifetime risk of tooth decay for children and adolescents who are exposed to fluoride when they're young. It still makes an important contribution to the dental health of adults, probably reducing rates of tooth decay in adults by about 30 percent.
