Since you only wore tray 7 for few days it shouldn’t have thrown you to much of the track. You should try placing tray 12 back and wear it for few days to see if teeth go back to the right place. If it doesn’t help please see your doctor so he can tell you what number is best to start at this point.
Damage with Invisalign Approach?
Hi there,I would agree that contacting your dentist is the best option. The sooner you contact your treating the dentist, the less it will affect/change the course of your Invisalign treatment.
Call your dentist who is treating you
You should call the doctor who is treating you. That is the best person to get advise from in this situation.
Dear issyb,Thank you for contacting RealSelf regarding your Invisalign question. At this time, I would contact your Invisalign provider. It is best to order additional aligners from where your teeth are now to ensure that your teeth will track properly. I hope that this helps and good luck!Best,Dr. Jenn
