Hold the dental floss with your thumbs and index fingers to start flossing
For finger-wrap method, hold the floss taut with the middle fingers
For floss-loop method, hold the floss loop taut with the other fingers
When the floss is held taut,
gently ease it down past the contact point of the two adjacent teeth
Then slide the floss into the space between the teeth into the gums until you cannot go any further
