Flouride in Water Raises Health Concerns for Some in New Jersey 29521

Residents of New Jersey are embroiled in a debate over whether the state should require each town to fluoridate its water, something that almost every other state does as a matter of routine.  The New York Times reports on the debate between medical groups, who say that fluoride is the best way to prevent tooth decay in children, and opponents who make arguments--based, officials say, on questionable science--including that fluoride is a carcinogen and it lowers I.Q. in children.
