For me, this floss was the right thickness, and coated so that it did not fray and get caught between my teeth. My Dentist recommended it, and I can understand why. I have tried other flosses that were either too thick, too thin, or no coated with wax, and they made flossing more difficult. It all depends on the spaces between the teeth though, and teeth that are capped, to determine the comfort and ease of flossing. I have a few capped teeth, and this floss helped me. I hope this review helps you.
