The teeth themselves are set inside the different,. the five pieces of this chuck, and they're a little bit harder than the rest of the skeleton. They have a higher magnesium content. Magnesium makes calcium carbonate, which is what the skeleton is made of. But the teeth are really, really hard because of this magnesium content.
