Brush up on how to brush your teeth
Are you brushing your teeth properly? Here's how to brush: Hold your toothbrush at a slight angle — aiming the bristles toward the area where your tooth meets your gum. Gently brush with circular short back-and-forth motions. Remember to brush the outside, inside and chewing surfaces of your teeth, as well as your tongue. Use a fluoride toothpaste and a soft-bristled toothbrush that fits your mouth comfortably. Consider using an electric or battery-operated toothbrush. Brush your teeth twice a day.
