The new "data" that there is no proof that flossing your teeth is beneficial is just one of many "scientific" reports that is designed to sway us one way or the other. I've been around long enough to have seen a lot of these. I've also seen their counter reports. Eggs are bad! Wait... eggs aren't that bad if you eat one per day. Butter is bad! Wait, it might be better than margarine... Coffee, beer, wine—all bad! Wait!!! They all have flavonoids that are good for you!!! So if it's just the same to all of you, I'm going to keep flossing my teeth every morning. I found out a while ago, that I do it "wrong" anyway; because I floss first and then brush. Apparently you brush first—which never made sense to me because I think my floss loosens stuck particles that are cleaned away during brushing. But then I'm no "expert." Still, I intend to keep flossing and to keep doing it the "wrong way" just the same...
