According to my dentist, I don't floss enough. "Only floss the teeth you want to keep" she said. Ok, guilty as charged - I know I don't. So after my last visit a few days ago, I vowed to her that I'd change that. Enter my iPhone and daily calendar reminders! Now at 8:00am and 8:00pm, my iPhone is setup to alert me to go floss. So far, this system is working well - haven't missed a day.
