I've just started my Invisalign refinement and am on aligner 1 of 10. My ortho's assistant has instructed me to wear each aligner for 7 days. She assured me that if my aligners are seated properly, I can change them weekly. She suggested using Chewies several times a day, in order to get them seated. I asked her why my case was special enough to change them weekly and she said my teeth were "loose" and were able to move quickly. She assured me she did the same for her refinement, as well.

Answer: Can I Change Invisalign Aligners Every Seven Days?
It’s possible for an attachment to wear out or partially break of over time. Depending how far along you are in treatment your doctor might choose to not replace it. If the tray is not sitting in all the way that might also cause the attachment not fully fill in the mold.
If your overbite is that extensive Invisalign might not be the best option. It would only be able to decrease the overbite slightly so it really depends on what your end goal is. They would also have to evaluate if tooth extraction is an option to fully correct the overbite.
You can certainly get your cavities filled while you are in aligners. Given this situation, I normally fill one or two cavities at a time to make sure aligners still fit properly afterwards rather than filling them all at once.
