We're sorry to hear your floss picks are shredding while trying to floss, and we'd like to help. We have many quality checks to ensure only the best products reach you. We recently transitioned to a new microtextured fiber that provides the same benefits you love and allows you to slide 50% more easily between tight spaces. As a loyal Oral-B user, you know this isn't the experience we expect. So we can learn more and help further, please give us a call at 1-800-566-7252, 9 am-6 pm EST, Monday-Friday.
