(50m + 5m) x 2 pieces For those who want to gently care for their interdental spaces. Healthy interdental spaces with floss containing propolis. REACH Dental Floss Wax with Propolis, reaches the gingival sulcus. [Instructions] 1. Cut about 40cm of floss and wrap it around one middle finger 2 or 3 times, and loosely wrap the rest around the other middle finger. 2. Use your thumb and index finger to hold the floss taut, with a space of about 1-1.5cm between your fingers. 3. Gently move the floss back and forth along the tooth surface, gradually inserting it between the teeth. 4. Once you've passed the point where the teeth meet, insert the floss slightly into the space between the teeth and gums (gingival sulcus). Even in a healthy mouth, there is a gingival sulcus of about 2-3mm, where plaque tends to accumulate, making it a particularly important care point. 5. After finishing one area, wind up the used portion and advance to a clean section. Rinse your mouth after use.
