The Fluoride Argument: Beneficial or Not?

If there’s one water matter that causes much debate, it’s fluoride. Some say it’s good, some say it’s dangerous. What are the facts? As with most controversies, it lies somewhere in the middle.

Last year, my dentist nearly jumped out of his seat when I alluded to the controversy surrounding fluoride. “There’s never been a single thing that has been a better way to improve the health of teeth in our country!” But there are other dentists that disagree.
