It takes time, can be painful to sensitive gums, and is just plain boring. So goes the argument against flossing. That’s why Gummy Floss decided to add a string of color and a few lines of flavor to motivate kids (and adults) to floss and brush daily. Medical grade silicone rubber makes for a soft, smooth and flexible floss that reduces bleeding and is more comfortable. For $15, backers get two bags of Gummy Floss, which equals 20 gummies.
