We know how important it is to have a floss you love, and are sorry you're unhappy with the recent changes to our Comfort Plus Floss. Please know, we have many safety checks in place to ensure our products are safe to use as directed. If you've experiencing pain, we recommend you discontinue using this floss. Oral-B is always improving materials and looking to ensure that we deliver the best products. As a result, we’ve transitioned to a new microtextured floss fiber that’s still strong and shred resistant. So that we can learn more and help you further, please give us a call at (800) 566-7252.

That does sound frustrating! This can happen when the floss comes into contact with a rough tooth or surface. We'd be happy to help you further, please give us a call at (800) 566-7252.
