Teeth are not your typical organic matter.

They would fit any reasonable definition that I can think of. Now,
fillings, that's something else.

Didn't say they weren't organic, just that they aren't typical in terms of
being burned up in a fire. One study has 85% of the teeth tested survive a fire
lasting 50 minutes in which temperatures exceeded 1,000 degrees.

A typical aluminum skinned airliner subjected to such temperatures and then
having a a few floors of a building collapse on the wreckage is going to all but
obliterate it to casual inspection; but human remains inside are likely to still
have recoverable DNA.

I think the bulk of a tooth is inorganic, and contains no DNA
but the innermost part has the nerve and a little flesh and blood
that is organic, and does have DNA. But if the tooth is heated
long and hot enough that DNA will be destroyed.

Besides, separating bone fragments and teeth from pulverized plaster
and cement, while no doubt doable, could not have been thoroughly
done within the amount of time during which the debris was removed
and disposed of.
