I've read this thread in upper amazement! I've never flossed my teeth in my life and my dentist never even recommended it. I can't even floss: I have this metal threads glued to the back of my teeth, to keep them in place after having braces... Those things disable flossing... I do use toothpicks though, because I can pick between my gums and the threads... But I think none of my friends and family members floss, never seen any of them doing it.. Maybe it's an American only thing? (I apologise beforehand if you're not all American who posted in here )
