Should my Vivera fit perfectly? Teeth shifting. (photos)

Question

Just started Vivera and am noticing that my teeth are shifting. Do my Vivera fit properly? Are my teeth shifting as a result of not fitting properly? Photos below. Hopefully you can see. I'm not applying pressure. I just used dark objects hoping that you can get a better picture of the fit

Your Vivera retainers should fit just lite your Invisalign aligners fit. From the photos that you sent it does appear that the retainer is not fitting properly.  That being said, if you are wearing them as prescribed even with the slight area that is not fitting they should not shift on you.  I would call your dentist and let them know your concerns.  Good luck.
