Advantages of Flossing Every Day: The theory is that the matter between the teeth is the actual source of dental disease. Flossing will clean the area between the teeth, thus preventing plaque buildup that can possible lead to cavities and gum disease. Importantly, it is recommended that teeth are flossed prior to tooth brushing, because then the fluoride from the toothpaste can access the area between the teeth.
