I only floss during the week before my next dentist appointment, and only then so that they don't give me **** about not flossing.
This report is music to my ears. I hate flossing. And my next dentist appointment is in two days. Can't wait to bring this up!
Basically, the report is saying that the evidence in favor of flossing sucks. It doesn't mean that flossing has no effect, just that we can't conclude anything one way or the other. Basically, there is no basis for dental societies telling us we should floss daily.
