There is a reason that a small package of dental floss is in the bag patients get at the general dentist. When used regularly, floss removes food particles from between teeth and reduces plaque buildup. The result is cleaner teeth, fewer cavities, and healthier gums. The ideal time to floss is right before brushing, but it is better to do it at any time than not at all. Each piece of floss should be gently pushed into the area between the teeth, then carefully curved around the base of each tooth. A clean section should be used for each space.
