I just discovered this kind of product, and I wonder how come it's so hard to find in France. Having quite clenched teeth, I was afraid that the wire does not take the time, but in fact, it is stronger than conventional dental floss, that I broke, or rather often tore. Very convenient to use, so I pass on a 2 times a day, in addition to brushing. Infinitely more practical than conventional wire, try it and adopt it;)
(My opinion regarding the full DenTek clean, I will update my review once tested this variant one, as I ordered three variants of a sudden)
