Not enough. Guess I should start that, eh? Nothing gets caught in my teeth and my teeth are close together so it's a pain in the ***. I use mouthwash twice a day instead.
2 times daily. I got sick of my dentist nagging me. =p
every couple of days, or whenever something gets stuck
As often as I floss my a#s, Never.
At least once a day however through the day if I eat something like pistachios which can get caught between my teeth then it's a spot floss too.
After every meal, as I have an annoying gap which things always get stuck in (worst offenders being lettuce, small seeds and bacon)
Often depends on what I eat, but usually at least once a day. Of course, corn on the cob means a couple of flossings after just one meal
