Then you take your pointer fingers and thumbs and grab the floss and go inside your mouth and in between the teeth. You can move at any angle to reach the teeth. I use several different angles when flossing. This is the correct way to floss and makes it very easy to reach the back teeth and floss even if you have larger fingers. Just give it a try next time. It might feel awkward the first time because you are not used to flossing this way, but trust me - it is so much easier!
Another flossing tip: as you use the floss, unwrap it from the middle finger and wind it up on the other middle finger, so you are always using clean floss between each tooth.
Happy Flossing. :)
