Can Invisalign move a tooth to replace another?

Save every tooth in your mouth!
My advice is to try and save every tooth in your mouth. There is a reason why molars (flat teeth) are in the back and premolars (skinnier teeth) are located more towards the front. You should have root canal therapy in both premolar and molar, then crowns on each made at the proper level, then an implant on the lower. Intrusion of a tooth is very difficult to do.
Every case is different. Invisalign is able to do many complex cases that was not possible before but there is no guarantee of anything until you are actually seen to evaluate the gap and the condition of the teeth. The best way to answer you is to have you come in for a complimentary exam to accurately guide you in what should be done.
