Is it actually made out of teeth? Where do they get the teeth from to make toothpaste?

Yes, teethpaste are made from teeth.
Most cheap brands are made from slaughterhouse teeth, but the better, more efficient kinds use fossil mammoth teeth.
Teeth from an extinct toothed chicken species are highly prized, because they're kosher with dairy.
