Well, if you generate enough smoke, I guess it's true that food
burning in any metal pan could kill birds at some point. But teflon
heated to high temp generates a specific chemical that is highly toxic
and will kill biirds. A stainless, cast iron, etc will not do that,
so its not all the same.

As for the question, if the pan was overheated on for a considerable
time and won't clean up, then it should be thrown out.
