Can I Treat my Teeth Gaps with Inman Aligner? (photo)

Your dentist would have the best information on how long they want you to wear your aligners. The refinement trays might have less movement build into each tray so you would not need as much time with them. Seven days still seems very short so just check that this is what they want you to do.

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.

If they weren't included in your treatment then you can expect to pay $500-$750 in most areas. $1100 does seem a little high. You can go to any Invisalign dentist to get Vivera retainers. 

I would speak to your doctor about your concerns. Invisaling does have some limitations so be sure to ask if your result is due a treatment limitation or if you need some more aligners to get the correction that you desire.
