You know how human teeth have those prong bits that anchor into the gums, the “root”? Inside those are the nerve canals: spaces filled with a pulp that nerve endings run through.
Shark teeth don’t have these canals in their root. Their teeth aren’t anchored into the gums and don’t connect to any nerve endings.

But do they get head-freeze if they eat it too fast?

that’s why they can have so many teeth,
imagine humans with10 times the amount of teeth, and therefore 10 time more likely to get tooth ache.
