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
I always recommend to postpone the crown until the tooth is asymptomatic. There might be some accessory canals that are not taken care off or the tooth might be fractured. I wouldn't place a permanent crown on a tooth until the pain is gone.
If your crown is out you need to see a dentist ASAP to prevent further damage & possible infection. A dentist will evaluate your tooth & crown, & recement it if possible or advise another treatment.
I think Invisalign will be a great option for you, you can probably get Express 10 which costs less than full.
Occasionally due to clinical limitation when taking impressions, wisdom teeth on the models are not accurate, in that case invisalign leaves out half of the wisdom teeth. in my experience it doesn't effect the treatment at all.
