What the Yuck: Is it gross to reuse floss?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Q: Am I totally gross for reusing my floss picks?

Well, you’re not gross. But, yes, the practice of reusing your picks is!

Floss is used to remove plaque, food particles, and bacteria from between your teeth. If you reuse it, you may reintroduce the old bacteria, which can lead to more plaque, and even some new varieties of bacteria that may have been lurking wherever you store your picks.

In other words: bad idea.
