the main thing I think of is whether you wash your hands after. If you are putting your hands in your mouth, I'd be a little uncomfortable shaking hands when you were done (or now I'm imagining someone flossing and then going to press buttons on a communal printer...)

but flossing is good.

I like this point. Maybe after I floss I use some hand sanitizer

maybe just floss with hand sanitizer?
