I've heard a few times about peoples gums hurting. One thing that I haven't heard though is flossing! If you try flossing, not once a day, but twice a day, your gums will thank you! It's exercise for your gums and it gets them good and tight. I know I sound like a dentist a little bit, but it really does work. I've done it once a day most of my life, but when I changed to twice, it made a huge difference. It takes 2 minutes and it's probably the best thing you could ever do for your gums.
