Follow these simple steps to brush your teeth:   Put a dime-sized amount of fluoride toothpaste on the bristles. Place your toothbrush at a 45-degree angle to the gums. Use short, gentle, back-and-forth strokes over each tooth. Brush the outer, inner, and chewing surfaces of each tooth. To clean inner surfaces, use up-and-down strokes by tilting your brush vertically. Consider dividing your teeth into four quadrants as you move through your mouth, and brush each quadrant for 30 seconds each while spending about two seconds on each tooth. For example, brush the outer surfaces of your upper teeth for 30 seconds (16 teeth at one second each), followed by the inner surfaces of your upper teeth for 30 seconds followed by the chewing surfaces. Repeat this for the lower teeth.  Rinse a couple of times to remove the toothpaste from your mouth.
