Answer:

D

Step-by-step explanation:

The reason why I think it's D is that this question is in the past tense. It wouldn't make sense for the sentence to have the word "have" Since the patients' teeth have been decaying for a while now (Going by the sentence) had would make more sense.

Answer:

D. had long decayed​

Step-by-step explanation:

When you need to talk about two things that happened in the past and one event started and finished before the other one started, place “had” before the main verb for the event that happened first.
