On Invisalign tray 9 of 22 and I'm worried that my progress is not on track? (Photo)

Invisalign moves teeth in small increments over time with the sets of trays that you are given. From the photo, it does look like the space is smaller between the edges of your two front teeth. Your Orthodontist would definitely know best if your teeth are on track because he/or she would know exactly how the tooth movement was planned and sequenced. I would not be worried at this point! Give it a little more time and continue to address your concerns with your Orthodontist if you have any.Regards,Dr. Pam 

Simply look at your aligners in your mouth after two weeks wear.  Are the teeth fully seated without air gaps?  Then you are on track.

Thank you for posting your question.  The best way to know if you are on track is to compare the clin-check to what is happening in your mouth.  Ask your orthodontist to show you the clin-check so you can see at what stage Aligner will show you what you are looking for.  There does seem to be an improvement but without seeing the set-up on the clin-check I cannot tell you if you are tracking on schedule. If your orthodontist says your tracking on schedule and knows that the gap is your primary concern then I wouldn't be worried.  See the clin-check to ease your mind.  Hope that help! Good Luck!
