Here is how to hold the floss properly to get an excellent grip so you can floss efficiently:
1. Cut a piece of floss that is about half arm's length.
2. Hold the floss with the thumb and the pinky in one hand.
3. Wrap the floss at least twice around the pinky and ring fingers with the floss going up the palm side of the hand and down the backside of the fingers.
5. Pull tight the floss and release your thumb.
6. Grab the floss with your middle finger and tuck in your pinky, ring finger, and middle finger to further secure the floss against your palm.
7. Grab the loose end of the floss with your thumb and index finger.
8. Repeat steps two to seven with the loose end of the floss and the opposite hand.
If the floss is secured, you will be able to release the floss with the thumbs and index fingers, and the floss will still be tight.
You will only use the thumbs to press upward to floss your upper teeth properly. Likewise, to floss the lower teeth properly, you will use the index fingers only to push downward.
