Floss this morning? Not exactly? Anybody who's ever been to a dentist has heard it already: Flossing and brushing keep the gums healthy so your teeth don't fall out, etc., etc., etc. But don't stop reading. This story won't bore you with the standard lecture about why flossing is good. No, the news here is something the hygienist probably didn't say. It turns out more could be at stake than teeth. Maybe your heart, for instance.
WASHINGTON - It sounds like another can't-win situation for the health-conscious consumer. Bottled water, missing bad stuff, is also missing something most scientists say is good. Millions who have turned away from the tap are giving up a primary source of fluoride, the public health system's main weapon against tooth decay. Americans drink almost 3 billion gallons of bottled water a year, a gush from a trickle a dozen years ago. Some home filters also remove fluoride. Is that bad for dental health? Scientists are not sure. People get fluoride in other ways.
