The teeth look probably OK.
It is hard for me to say. How can you tell? Let me describe what I can observe. If I push and pull on one crank arm the entire crank moves a bit. Not up and down but back and forth. Inotherwords, I can see the chain rings and other arm move when I move the left arm. It is like the crank is a smidgen too wide for the bracket. It is possible that there is a bad installation as the bike was originally obtained from an incompetent source.
If there is anything else I can try to diagnose this let me know.
