Pattern on tooth fragment?

I don’t expect this tooth fragment can be identified but I’m curious if any one has ever seen enamel like this? It seems to have a thin clear outer layer and the layer below has the dots. Found Myrtle beach where Cretaceous, Pliocene, and Pleistocene fossils can be found.

My guess - it is an artifact of the mineralization of the piece.

I'll go along with Tony, also guessing. Results of weathering/chemical processes?
