For brushing, just brush your teeth gently and pay special attention to the areas where your teeth and gums meet. Clean the surface of every tooth by brushing with a circular motion and use the tip of the bristles to clean behind the upper and lower front teeth
For flossing, take a generous piece and wrap it around your middle fingers. Using a clean section of floss each time, wrap the floss around your tooth in a C shape. Then, wipe it over the tooth from base to tip. Repeat for every tooth.
