Flossing.

Here’s How To Floss You should floss under both sides of each flap of gum tissue between your teeth. The following technique is very effective: Break off about 18 inches of floss and wind several inches of one end around one of your middle fingers. Wind several inches of the loose end of floss around the middle finger of the other hand. Grasp the floss with the thumb and forefinger of each hand, leaving about an inch of floss between the two hands. Pull the floss taut and use a gentle sawing motion to insert it between two teeth. When the floss reaches the gum, curve the floss into a C-shape against one of the teeth. Slide the floss gently into the space between the tooth and the gum until you feel resistance. Holding the floss tightly against the tooth, scrape up and down five or six times along the side of the tooth. Without removing the floss, curve it around the adjacent tooth and scrape that one too. Repeat on the rest of your teeth. Don’t forget the far sides of the rear teeth. When the floss becomes frayed or soiled, a turn of each middle finger brings out a fresh section of floss. After flossing, rinse vigorously with water and then brush teeth.
