Native Americans ate them all the time. They would smoke them or slow roast them. A lot of archaeologists often confuse drum-fish teeth with human infant tooth caps.
I've caught a couple thousand of them I reckon. But I never knew they had teeth.
So I googled it.

As for eating them, I would have to be getting pretty hungry first.
