Used waxed floss (unwaxed floss is more likely to get caught and shred in your braces), dental tape or a product specifically designed to clean around your braces.
Threader floss is great to use when flossing around braces. Use about 40cm of floss. Thread the floss carefully.
Take the floss and carefully thread it under the main wire of the braces before passing it between two teeth. Then remove the floss and re-thread it under the main wire to pass between the next pair of teeth.
Be sure not to snap the floss – simply move it up and down gently against the side of each tooth making sure to reach the gum line.
