[For healthy mouths with daily use] ■ Floss length: 55 yards (50.3m) ■ Waxed, non-flavored ■ This product is used by dental hygienists in dental clinics throughout Japan for interdental cleaning. ■ Even healthy mouths have grooves where plaque can easily accumulate. Brushing alone is still insufficient for oral care. It is important to thoroughly care for the gingival sulcus and narrow interdental spaces, where plaque tends to accumulate, with dental floss. By caring for the areas between teeth and the gum line, which are difficult to reach with a toothbrush, with dental floss, the plaque control effect is enhanced.
