Before. Then you brush out any stuff that you dislodge. (Ew)
I also floss before brushing, though I'm pretty sure my dental hygenist has recommended one way at one time and another way at another time (different hygenists, most likely...)
After...per many dentists and hygentists I asked. With that said, however, I think they would all say that all that matters is that you do floss.
Jill, you're right! I can't believe I hadn't thought of it that way before.Melissa & Hilary, Kansas Dad agrees with you. He's a before guy. I've always flossed after, because that's the order at the dentist's office. Though I'm almost embarrassed to admit I've never asked. (I think I'm just in too much of a hurry to leave.)
So I just checked the ADA site. It says: "Either way is acceptable as long as you do a thorough job. However, if you use dental floss before you brush, the fluoride from the toothpaste has a better chance of reaching between teeth."http://www.ada.org/ada/seal/floss.asp
