so I used to think this (till this past week), it's not quite true. Yes, ther are images of showing child skulls with lots of teeth. those are generally hyperdontia.

A regular child skill looks more like this x-ray

Yes, you can see the adult teeth, but not all of them, and not like the hyperdontia cases.
