Hi Cassidy 91,
I think I might be one of those people that you've seen whose teeth have moved fairly quickly in 5 months. But don't get discouraged by cases like mine! Here are a couple of factors that might be contributing to my quick movement:
1) My ortho is using a fairly new procedure called "Controlled Arch" on me, where I have to have upper and lower expanders to widen my arches and move things along. I also have special brackets for this procedure. My brackets are also metal, which allows the ortho to put more force/torque on my teeth.
2) My upper teeth were not that crowded to begin with (my lowers were the problem)
3) Even though my teeth have 'leveled out' a lot (i.e., they have fallen into a straight line), there is still a lot of work to be done on my mouth. My bite is still completely off (none of my teeth touch when I bite down). So, even though I have seen a lot of progress in 5 months, my original 'sentence' was a year and a half, and I believe my braces will be on for that entire time!
So, my point is that some people just have factors that make their teeth move more quickly (I'm sure even genetic, physiological, and biological factors come into play here)---so don't worry, your teeth will move in their own time!
