Flossing can be awkward, difficult, and time-consuming or maybe you just don't understand the importance of it, but it's an essential part of your daily cleaning routine. Floss at least once a day to achieve optimal oral health. Daily flossing helps remove plaque from the areas between your teeth where a toothbrush cannot reach. If this plaque isn't removed daily is turns in to tartar (AKA calculus). Flossing helps prevent gum disease and cavities.
