Help : malformed newborn ball python

[Bogertophis]

Thanks for your answer

I thought that his jaw might get back into place during the first meal

I'm thinking of doing an x-ray at a vet...

Otherwise, this baby has normal behavior, is active, curious, moves quickly ... no other problem

Are you sure some of his teeth aren't "caught"? That happens sometimes with snakes of any age, like when they hit the glass going after motion, but it could happen
just as well in the egg I would think. And that could explain his awkward tongue flicks too...
