I purchased this at the recommendation of my dentist, but I no longer use it, so I'm offering it to someone who can. Oral Care Floor Floss 45m Product Features Gentle dental floss for gum health, preventing periodontal disease. Essential for preventing periodontal disease is removing gingival plaque (attached to the gums) 1 to 2mm above and below the gum line. Floor Floss has 384 fibers that expand gently, removing plaque below the gum line, which is crucial for preventing periodontal disease, without damaging the gums. ● For those who are still experiencing periodontal disease despite using dental floss. ● For those who are not able to care for above and below the gum line. ● For those who have had painful experiences with other dental floss and have developed a dislike for it. ● For those who want to experience a thorough cleaning sensation.
