Closer to the former. Shed theropod teeth are quite abundant,
far more abundant than almost any other dinosaur remains.
[In fact the uneven tooth size in a T. rex jaw is largely due to
different ages of the teeth].
However, a tric' or edmontosaur that rips lose has a good chance
of escape, thus not providing any food for the T. rex. So holding it
close while killing it would increase the chances of a successsful
hunt. It is *this* more than the loss of teeth that was probably
important - that plus the reduced danger of being gored by a tric' that
is held by the back while being slashed.
The peace of God be with you.
