Use the so-called bass method or bass technique to clean your teeth thoroughly and systematically. Place the toothbrush at a 45° angle to the gums and teeth, pressing the bristles lightly against the teeth and gums. Make at least 10 small, shaking or circular back and forth movements per tooth. This removes food debris from the tooth surface and from between the teeth. Then brush with a kind of wiping motion from the gums to the chewing surface and continue with the neighboring teeth. Clean your teeth systematically: first the outer surface, then the inner surface and finally the chewing surfaces.
