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,

Well no, unless its an artificial replacement a tooth was
made by the body that its attached too and is by definition organic.

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.


True but a tooth is essentially a sealed ceramic capsule.
Its a matter of record that DNA has been retrieved from
victims who's bodies were reduced to charcoal in a fire.

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.


Well no, it was done while the wreckage was being sorted and
sifted off site and they had several months to do this.

Again they recovered considerable such samples
from the Oceanic crashes of TWA-800 and SwissAir 111
so recovery from the WTC is quite believable.
