I always thought that flossing mostly moves the dirt from between your tooth to another side. So I always brush after flossing.

(I also never thought about fluoride so of course I rinse after brushing and I will continue to do so because otherwise it would be very uncomfortable)

As far as I know a function of flossing is to disrupt bacteria in places that your brush can't reach.

Presumably another is to dislodge food stuck there.

I can imagine that floss + rinse would accomplish both well enough, especially if it's twice a day (but surely most people brush one a day)
