I changed to Tray 12 after dinner Tuesday night. The next morning, my teeth were sore, but (as you may have seen in a forum post), the tooth with the messed up attachment hurt significantly more than any other teeth, hurt more than any tooth since starting Invisalign, and it even hurt down to the root. I was concerned about this but decided to wait a day and see if it got better. My other teeth weren't sore on Thursday, but that one still was. I called the ortho but he was out on vacation this week, so I couldn't have him look at it anyway.
Good thing is, the pain left yesterday. I'm still weary of this misplaced attachment though. It doesn't fit in the bubble like the other 14. If the root pain happens again next tray, I'm calling the ortho. I'd rather he take the attachment off then deal with this for the other 7 trays!
Other than that, things seem to be going well with treatment. I'll be an Invisalign teenager on the 16th. Come the end of this month, I'll be Invisaligned for 6 months!
Here's pictures of my teeth as of Tuesday night
