Ok, i hate flossing, but I can see with my eyes it's useful.
After some really minor problem I upgraded to a good quality floss and
that made things better. But still, it's a pain.

I wonder if there is any reusable tool, like the one-use plastic thing
with a piece of floss on top, but whose floss can be replaced. That
would be useful, and way less expensive. I was thinking of building the
thing myself, sort-of inverted, slim scissor that would allow you even
to manually modify the tension in the floss while you floss... but is
there anything off the counter, as far as you know?

Thanks
