This is the dental floss I've been using a lot lately! Honestly, I feel like brushing alone isn't enough; I believe you need to use floss to completely remove food particles. First of all, it is very long—50 meters—so it lasts a long time. I didn't really feel any irritation to my gums. It has a subtle mint scent, and since it is a refreshing smell, it is not off-putting.
