Good point (pun intended, as always).  I remember reading an anecdote in
Richard Ellis's _The Book of Sharks_ back in 1978, in which he described
running his finger along the serrations of a _Carcharodon carcharias_
tooth:  "I didn't know I had cut myself until I saw the blood."

Of course, the *cumulative* effect of a mouthful of _Carcharodon_ teeth,
as I recall, is generally an avulsion.
