For cleaning between the teeth because brushing can not clean the interdental area. Those who have braces should use dental floss help clean by inserting silk through under the wire, then thread through between teeth. To go down a little below the gum edge. I move the silk back and forth a few times on both sides of the adjacent teeth. The dental floss that is suitable for braces is a special type (Super floss), which is more convenient to use than other types.
