To keep your mouth thoroughly kissable, you'll need to do more than just brush. Floss at least once a day. It's good for removing plaque and food particles between teeth and between teeth and gums. Use a long piece of floss: 18 to 24 inches (45 to 60 centimeters). That way, each time you move to a new space you can use clean floss. Wrap the ends around your index fingers and run the floss vertically between your teeth and under the gum line. Rinse often to clear away debris. Don't panic if you bleed a bit, especially if you don't floss regularly.
Floss comes in varying thicknesses and in many forms, such as plain, flavored, waxed and unwaxed. If you experiment with different types, you may find that you have preferences. For instance, very thin floss is beneficial if your teeth are tightly spaced, or extra soft floss could ease pressure on sensitive gums.
