Ultimately, how many extra cavities, various other illnesses, and premature deaths will come from this hysteria is definitely something no study will ever be able to show
Toss the floss! Turns out dental flossing is barely useful, even worthless perhaps. So reported the Associated Press (AP) and subsequently more than 150 news outlets, including such as the Washington Post ("The Shaky Evidence for Flossing") and New York Times's more powerful "Feeling Guilty about Not Flossing? Maybe there's No Need." One Web site proclaimed "dentistry is a scam." Well, okay actually that was just Kanye West.
Only problem is they're wrong. But denture companies everywhere must be rejoicing.
Ultimately all this comes down to the old maxim that "Absence of evidence is not evidence of absence." More specifically, few studies have been done on flossing. There are several reasons for this but the most ironic is that the benefit is so darned obvious and has been observed by so many experts for so long.
