Fun fact - all of your adult teeth were already there from the start, hiding under(inside?) the gums. We don't "grow" new teeth when the baby teeth fall out - the adult teeth were always there under them.
I have a condition where my lower front permanent teeth never developed. We weren't sure if any of our kids would have the same issue so we discussed it with the dentist. They couldn't tell us if all the permanent teeth were present or developing because there hadn't been enough time for first xrays to show all of the permanent teeth buds growing. Even at age 3.
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.
