My dentist recommended using thicker floss than what I was using (Glide). This floss is thick and strong, and I haven’t broken any while using it, unlike with other brands. It’s not too thick, so I don’t have trouble fitting it between my closely packed teeth. It doesn’t have any flavor, which I like. On rare occasions, it will get stuck on a certain tooth and fray, leaving some of the material behind in my tooth. But that isn’t the floss’s fault.
