If you brush your teeth well enough, like you're supposed to, then flossing is but a redundant process.
Have I flossed in the last 10 years, certainly; could I tell you when said flossing took place--hell no, because it's not a habit of mine and yet, I've never had any gum or tooth problems directly related to the improper maintenance of my oral cavity. The only tooth problem I've had stemmed from playing H.S football.
Like I said, brush like you're supposed to, and you'll be good.
Im pretty surprised everyone is shocked he said 10 years, because I probably flossed about twice in my entire life, I brush my teeth 3 times a day and get in there
actually I dont think I know anybody that flosses everyday, I didnt think it was that common
