For years I've used Listerine woven floss, but for some reason I can't find it anywhere anymore. It was made of thread or string or something like that. It seemed to clean better than all of the plastic floss on the market, which seems to glide between your teeth instead of really clean. Plus it wasn't plastic, which is a good thing. I was looking for tongue scrapers and found this site and saw their silk floss. I like it! It's similar to my old floss and so much better than this rubbery plastic floss that I've been using. And the packaging is cool!
