I just knew the recent (a few years ago) announcement that dentists no longer recommended flossing (allegedly for lack of positive effect) was subterfuge to drum up more business.
My memory of that wasn’t that dentists stopped recommending flossing, it was just an acknowledgment that there hadn’t been any research that showed a positive effect. And not that the research had failed, there just hadn’t been any at all. I think most dentists continued to recommend flossing.
