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.

    What in the world would make you think to reuse floss? Do you reuse condoms too?

      For 10+ years I have tied loops in the ends of my floss so I can hold it easily without strangling the distal half of my 'flossing fingers.' I also use rinse with a small amount of peroxide before I floss to help bubble out bacteria. A year ago I started using G-U-M Soft-Picks by Sunstar every other night. I have gone from years of chronic gingivitis to a near perfect dental cleaning per my dental hygenist. It works for me and I reuse the floss. I also used an electric toothbrush. And as far as 'Yuck, reuse floss,' you use that same old nasty toothbrush for how long???

    How about TP. Reuse that too? Is that a yuck you're to embarrassed to ask your doctor about? Gimme a break!

    I have reused monofiliment floss for years and my dental hygienist says my gums are in excellent shape. Of course I also hydrogen peroxide that helps eliminate pesky bacteria.

    Of more concern is the use of the toothbrush. All those densely packed bristles that hold moisture, food particles and BACTERIA. And you pick on a single length of easily washed and dried floss. Shame on you. Now, maybe multifiliment floss has other characteristics. Best to go with a monofiliment and a small amount of peroxide.

    A "Bad Idea" is asking a medical doctor's advice on floss. If it works for you, do it, no matter what the AMA or ADA says.

    Thank you! My roommate leaves used and then reused floss picks all over the house and it is disgusting and embarrassing... especially when people come to visit and find them hiding on the dinner table between the salt & pepper shakers!

    What about reusing a toothbrush? Please explain how reusing a flosser would be any less sanitary. If you rinse or wash it I’d bet it’s way cleaner than your brush.

    I particularly am concerned about using the same floss pick for the whole mouth, not a whole month.
