Loose dental crown - should I leave it and wait for it to fall out?

So I have a dentist I’ve seen multiple times since January in regards to this. I have an upper front tooth that has had a root canal that is loose. It has been loose since January, and has progressively gotten more loose. My dentist says the post is loose, and he needs the crown to fall out before he can repair. He’s tried pulling it out with no luck over the summer. I have an appointment in 2 months. Does it seem wise to leave it as it is and wait for the appointment?
