Shark teeth are embedded in the gums of the animal rather than directly to the jaw. Sharks are constantly losing teeth due to wear and tear when they eat, though the teeth are replaced throughout the animals' life. Multiple rows of replacement teeth grow in a groove on the inside of the jaw and steadily move forward in comparison to a conveyor belt. Some sharks may lose 30,000 or more teeth in their lifetime. The rate of tooth replacement varies from once every 8 to 10 days to several months. In most species, teeth are replaced one at a time as opposed to the simultaneous replacement of an entire row.

Bought for bathroom decor
I bought several sets of jaws during the shark week sale so I could hang them in my shark-decor bathroom. They appear to be set with resin (since cartilage is not as rigid as bone) so they are perfectly humidity-safe. My only complaint is that there’s a great variation in how “flat” the jaws are, some of them curve outward very heavily. This is a really minor issue, though, obviously natural specimens will never be uniform. But it’s something you should have in mind if you are planning on mounting them to a wall vs putting on a shelf. I bought some extras so I could have my wall mounts and I’ll be putting the curved ones on a small shelf.
