Floss at least once a day. The floss needs to be pulled under the archwire. A floss threader facilitates this. Start by pulling floss through the threader.
Push the end of the floss threader under the archwire and pull the floss through.
Pull the floss up between the teeth and gently move it up and down the side of both teeth. Remember to move it up all the way under the gums.
Pull the floss out and use a different section of it for the next tooth.
