SO far these have not hurt my gums and none have broke or bent. The floss handle is very durable as well. These are a 2-1. It can be used as inter-dental brush or toothpick. They have helped remove plaque where I cant get my tooth brush and have helped with deep cleaning between my teeth and my gums. I bought these to travel with and they came with a portbable case. This makes them easy to use on the go. I can just toss them in my bag and take them on the go. I have bought several different brands and not all of them are created equal. A lot of the times they do not slide between the teeth easily. So far these have been great
