It's *almost* a perfect floss [SEP] I purchased this brand because what I used to use was constantly shredding. Good news: Oral B floss doesn't shred. Bad news: When I pull just a teeny bit much, it breaks in half -- otherwise I would be in love with it. I have really tight teeth, and it gets between them. But having to waste so much of it because of breakage makes its value go way down in my book.
