Flossing WITH braces is more important than flossing without them, because plaque collects around the appliance. Plaque is the major cause of gum disease and must be removed daily. Your orthodontic assistants can show you how it is held. The floss must be threaded under the archwire before it is passed between the teeth. Be careful not to snap the floss as it is moved between the teeth.
Steady pressure works best.
Do not force the floss hard into the gums, but be sure to clean the tooth surface under the loose collar of the gum tissue. The floss must be re-threaded for each point of contact area between adjacent teeth. Do not forget the back side of the last tooth. When done brushing and flossing, pull your lips and cheeks away from your teeth and inspect your work in a mirror. Metal braces should shine and your teeth should be free of the cream colored filmy plaque.
