> I spent a month of the year just flossing 1 tooth each night (ridiculous, I know!), then 5 months just flossing 1 row (better!)

Not directly related to the habit formation part, but this reminded me of something my dad used to tell us as kids about flossing and brushing teeth when we'd complain about it:

Dad: You know, you don't have to floss and brush them all.

Us (amazedly): Really?

Dad: Nope, just the ones you want to keep.

Just let the kids smell some rotting piece of food inside their mouth after flossing. Guaranteed they floss every time from then on.
