Wisdom Fangs

I've been contemplating the possibility that our wisdom teeth at one time contained venom.

I was in bed last night thinking about venom and how unfair it is that humans don't have any. Then I thought of vestigial tails and how unfair it is that we no longer have real tails. Which of course led me to the idea that perhaps our wisdom teeth back in the day were actually venomous fangs and what we now know as "wisdom teeth" are vestigial in that sense. How cool would that be?
