I've grown completely used to the Invisalign trays... I wake up in the morning and have to actually feel to even know they're still on. My teeth have moved considerably (to me) and I can feel the difference... and now, my teeth only hurt when I take them OFF, which I think is a good sign.
My only complaint at this point is eating. I've never been one to do the three-meals-a-day thing... I'm a grazer, and nibble at things, which I can't do now, since there's this whole take-them-off, eat, floss, brush, put-them-back-on thing. Frustrating.
I'd personally like to move on to the next trays early... maybe expedite this whole thing even... but I think the root canals in the tooth need to reroute a little, I don't wanna do any damage either... so I'll stick with it as is for now, and discuss it with my ortho next time I go in.
All in all though, good stuff :)
