Let me just start this by saying that when it comes to the human body, excess anything makes me deeply uncomfortable. Fingers, toes, heads — it all makes me super uneasy if it's beyond the number it's supposed to be.
But I've found that in particular, the idea of an excess amount of teeth is enough to make my skin crawl and my whole body curl into itself in an uncomfortable, anxious little ball of "nope."
So this story definitely got me good.
