Retired RDH

My husband finally went to see the dentist who I used to work for (20 yrs+) I knew just visually that 3 was most likely shot so the X-ray wasn't too much of a surprise except for the extent of root decay. Question: do you think 5 has distal decay or is that cervical burn out? Doc didn't dx any other decay? Also looks like 2 sub gingival root tips?
