I never liked to floss as a child, and my dentist always reminded me as she cursed my cavity-ridden teeth (as she was drilling them to bits).. yikes, well back to the now.. Im an adult, and i floss more regularly – but not twice a day or anything.. and I use this floss because its not as uncomfortable as running twine through your teeth. This is almost like a very thin flat piece of material, it feels like the same stuff grocery store shopping bags are made of. plasticy thin but gets the junk out of your teeth. 3.35 at http://www.drugstore.com/
