I have to see perio before getting my permanent crown molds done. Any suggestions? (photos)

I went to the dentist and had my old crowns removed. Gums where inflamed above two crowns due to poor seating and bulky crowns. my gums are pink/normal now. They said I have to see perio, I am curious as to why? Do my gums look unhealthy? I really want to get my molds done for my perm crowns. Dr said she would do it last time if no bleeding occurred, wich it did not. What would be the case for me not getting the procedure? Thanks!
