Dr. Tung's Smart Floss®
"I really like this floss. I'm still looking for a good all-natural floss that doesn't shred (this one is made of polyester fibers), but I think this cleans better than the thin drugstore brands. I have close contacts between my teeth, and this floss still works great. I don't think the cardamom flavor is very strong, and I don't mind it, but for those that are sensitive to flavors it may not be a match for you." — Corinne B.
