I try to go to the dentist/orthodontist as often as possible, but sometimes life gets in the way. Like most of everyone here, I get the usual "you need to floss more" comment, but in terms of brushing, I mostly get the "okay, at least you're doing this part well." Manual flossing is a bit of pain, with the string getting stuck in my teeth constantly and me having to yank it out (which causes it to deform a bit, making it unusable). I've tried using a WaterPik, and that's been working fine for me. I need to be more consistent with using it, though.
