Fluoride was introduced late enough in Zimbabwe that many of my childhood adults easily remembered life before it. There were many horror stories about the general state of teeth prior.

That being said, your dentist can apply fluoride to your teeth (boggles the mind why insurance won't pay the $50), and flouride toothpaste is still much more common than not. It's probably not needed in the water supply for dental purposes.

That being said, what are the other fringe benefits: such as microbe control?
