bent cog teeth?

Thinking it was a rear der problem, I adjusted it a couple times. But
in the middle cog I would get a jingle sound. After close examination it
looks like a couple of the cog teeth may be bent. I'm using shimano 9
speed, with the new SRAM 9 speed chain. Is it safe, or should I bend what
looks likes the offending cog teeth, or just put up with the jingle? The
new SRAM chain looks wider, then their older version, but how would I know.

Bend away slowly
