Can someone review these pics and provide your opinion.

I’m going to the dentist this week with severe pain when ice cold drinks hit this spot and on and off pain as well.
The tooth second to last is a crown. Do you think this is part of the crown that cracked to the last tooth having a cavity (or worse).

pulp is dying on crowned tooth - irreversible pulpitis likely. If bite is ok, likely an RCT is needed.
