Toothbrushes come in a variety of shapes and sizes, but choose one that fits in your mouth comfortably. Correct brushing technique means placing the toothbrush at a 45-degree angle toward your gum line and gently moving the bristles back and forth in short strokes. Make sure to brush the outer, inner and biting surfaces of all your teeth. Brush your tongue as well, or use a tongue cleaner to kill the bacteria that are there.all
