You can virtually eliminate plaque by carefully brushing and properly flossing every day. It's really that simple: your toothbrush cleans the tops and sides of your teeth, while the floss cleans between them. Flossing also polishes teeth and controls bad breath. An extra two or three minutes spent flossing each day can give you a huge advantage in the war against those bad bacteria. The American Dental Association (ADA) recommends brushing twice and flossing once daily.

Correct flossing is a fairly easy thing to learn: either via the spool method, if you're quite dexterous, or via the loop method if you're less nimble with your fingers. To use the spool method, simply pull off about 18 inches of floss and wind most of it lightly around your middle finger. Don't pull tightly and cut off your circulation! Then wind the remaining floss around your other hand's middle finger to take up the used floss as you go. Now, push the floss in between your teeth using your index fingers and thumbs. Gently bring the floss up and down several times around both sides of each tooth, making sure to reach below the gum line, forming a C around each tooth with the floss. Pull or push it against your gums carefully so that you don't hurt them; avoid rubbing it from side to side.
To use the loop method, pull off an 18-inch strand of floss, then make it into a circle. Tie the circle with three secure knots, and place all of your fingers (not your thumb) within the loop. Next, use your index fingers to direct the floss through your lower teeth, and your thumbs to direct it through your upper teeth. Again, be sure to clean below the gum line, and make the floss form a C around the sides of each tooth.
If you're not especially skilled with your hands, or if you have to floss someone else's teeth for them, you may want to consider a pre-threaded flossing tool. These small plastic devices come in bulk packages at drugstores. They are rather inexpensive but very effective.
