Has this permanent crown (#18) been done correctly? Do I need to redo it? 3 weeks po. (photos)

During 3 weeks after the crown procedure, I had severe gum inflammation and had antibiotic treatment. One month later I went to another dentist who told me that the crown margin is too deep into the gum which is still irritating the gum and referred me for crown lengthening. The periodontist thinks the crown shouldn't have those pointy parts, which traps food and may cause loss of bone in long-term. She recommended to extract the wisdom teeth (pushing on the crown) and redo the crown.
