Can I get Invisalign/Braces if I have a tooth infection and missing one bottom tooth?

I actually have 2 issues at the moment. 1.) My upper back tooth is infected and there is a small bump in the gums. Had it for years but no pain. Root canal was suggested. 2.) My bottom molar was extracted due to infection and months later, my dentist notice the tooth above it is slightly growing downwards. He suggest I get a bridge for the missing tooth below. However, my goal is to have invisalign for my upper teeth. Is it possible to take care of the other issues later? Thanks!
