How to floss properly:

   It's important that you floss between your teeth at least once a day. Most cavities and gum disease start between your teeth, where your toothbrush just can't reach. Flossing removes the plaque from between the teeth and below the gum line. Plaque is the culprit in tooth decay and gum disease. It is a sticky, invisible film of bacteria and food residue that regularly attaches to the teeth. If you don't floss every day to remove the plaque that forms daily on your teeth, the plaque will harden into calculus (also called tartar) which can't be removed by brushing or flossing. Tartar causes even more problems, as it traps the destructive bacteria against the tooth and gums.Break off about 18 inches of floss, and wind most of it around the middle fingers of each hand, leaving about five inches of floss unwound. Pinch the floss between your thumbs and index fingers.
   Gently glide the floss down between two teeth, using a side-to-side sawing motion. If it's difficult to fit the floss between your teeth, or if it snags or tears, let us know. There may be a problem that need to be fixed.
   Pull the floss tightly into a C shape around the side of your tooth, and slide it under the gum line.
Clean the side of the tooth, using an up-and-down motion.
The floss will 'tell' you that you have removed all the plaque by squeaking a little as it rubs against your tooth.
