My aligners don’t fit right, 2 days into first Invisalign tray, is this normal? (photos)

Hi, thanks for sending your pictures and question. There appears to be significant gaps on your aligners. You need to visit with your provider. All the best.

Invisalign aligners are supposed to fit your teeth perfectly, otherwise your teeth won't move the way we planned them to do.
You need to see your Invisalign provider as soon as possible to evaluate the issue. Good luck

If invisalign aligners fit PERFECTLY and INTIMATELY, there would be no room for teeth to move TO.  It is possible that your aligners should fit MORE than what you show, but you should NOT expect them to fit like a retainer.  Wires, as in traditional braces, have what is called memory.  They are the shape they SHOULD be, and when placed onto crooked teeth, the wire deforms and puts pressure on teeth while trying to get back to the original shape.  Invisalign aligners do NOT have memory.  They can stretch a little bit (not a LOT), so there must be space to move TO.  Each aligner will move a tooth "around" 0.2mm, so it IS a slow process.However, teeth don't always "track" or move as anticipated (as designed in the Invisalign Clin Chek).  When teeth don't track, subsequent aligners will not fit, so teeth won't move as planned.  A "mid course refinement" is then done (new impressions and new aligners created and ALL the old aligners are tossed into the trash).Go see your dentist/orthodontist.  They will know what to do.
