Pointy Teeth and Legacy Wraithlings

In the Legacy series and some fanons, young Wraith are said to be fruit-fed. Yes, that can work: some of the biggest canines on Earth belong to those who are herbivores or primarily herbivores. Fruit bats have mouths full of sharp, pointy teeth. Having pointy teeth means nothing. Besides, Wraith teeth are not even all that large or sharp and certainly human teeth are even less so.
