Take a passage of the floss in between your index finger and your thumb. You don't own to roll it around your fingers, just hang on to about an inch between the finger and thumb. Point your finger to the subsidise of your teeth and while keeping the thumb close go to the backside of the closing tooth. Make a "C" shape around each side. Move forward doing like peas in a pod thing. Maintain the inch space going down and coming up. Rub pay for and forth till the floss breaks the contact, then rub up and down and around rather in that "c" shape down into the gums. You won't be righteous at it, it'll take practice. Try not looking surrounded by a mirror if that is confusing you.
The flossers are fine, but sometimes thorny to get within or out if your teeth are really tight. The also can't make the "c" shape so guide it toward respectively tooth as much as possible, not just straight down.
