The last time I had my teeth cleaned, the hygenist kept mentioning how good I must floss and that I only missed one or two areas and even then they were trivial to clean. Finally after 3-4 times of hearing how great I flossed I finally broke down and told her that I never floss, beyond occasionally using one of those flosser sticks as a toothpick, but never with any regularity. She just couldn't believe it.
