Invisalign Difference, Side by Side

I began my first set of Invisalign on February 9.  I am currently on my 11th tray, and have 5 more trays for my upper teeth before the scheduled "completion" -- although according to various blogs by people who have undergone the Invisalign process, adjustment trays are very common and the alignment continues beyond the given number of trays.

I have kept all of my trays, and tonight decided to see just how much adjustment has been made on my upper teeth... putting Upper Tray #1 next to Upper Tray #11, the difference is quite impressive:

On the left is my first tray -- basically, where my teeth began.  On the right is my current tray, where my teeth are at this moment.  Notice that the recessed tooth part of the tray is much more evident in the first tray, while it is less apparent in the current one.

Pretty cool!  Come on, teeth!
