For most of my life I brushed but never flossed. I had no cavities but I was at risk of losing my teeth due to plaque below the gum line. My teeth were loose and gums would bleed when I brushed. I've had all that fixed and now floss regularly. In retrospect flossing seems more important than brushing.
