This book reviews the effects on health of fluoride ingested from various sources. Those health effects reviewed include dental fluorosis; bone fracture; effects on renal, reproductive, and gastrointestinal systems; and genotoxicity and carcinogenicity. The book also reviews the Environmental Protection Agency's current drinking-water standard for fluoride and considers future research needs.
