It’s unlikely that you will wear only a few teeth. One should expect to wear all evenly. That said:

-the teeth of chainrings designed with profiles to assist in shifting will have different profiles making some look worn compared to others.

-it is possible to damage some teeth during shifting under power. This is more likely with softer aluminum rings. I have seen both bent and sheared off teeth as a result.

-if your chain is worn it can contribute to premature ring wear, but all teeth, not just a few.

i suspect that what you see is normal tooth profiles. Where is the clunking coming from?

Check you chain for wear and replace it if it is very near, or completely worm. If it is very worn you your cassette may be as well and should be replaced.
