I had the most difficult time with flossing because my teeth have minimal space in between them. The struggle to get all my teeth adequately flossed turned me off to regular flossing. I finally broke down and bought a water flosser and it's made a HUGE difference in my ability to floss. It took a little while for me to get used to it but it's made regular flossing so much easier for me. No more string floss for me!
