This is an image of a shark denticle from a lateral view. Denticles are very similar to vertebrate teeth, as they consist of a pulp cavity, surrounded by dentine and an outer layer of enamel-like material 🦈🔬

This is the ventral view of a hatchling shark head, stained with alizarin red. You can see multiple multi-cuspid tooth generations in the jaws, and dermal denticles which have defensive and drag reductive functions 🦈🔬
