if toph can bend minerals in the ground, is it not a stretch to assume she can bend calcium? and if so, can she then bend teeth? like some sort of freak tooth bender?
Well, I mean, we know that earthbenders can bend crystals. Bumi does it in Season 1, Episode 5, obviously, and then there’s the whole thing with the Dai Li in the Crystal Catacombs. Crystals are minerals, just like calcium, and since earthbenders can bend crystal just fine, technically there is no reason that calcium would be too much.
(I cannot express to you how much it pains me to say that.)
Bones are made mostly of calcium phosphate (also a mineral) and a protein (collagen). Considering earthbenders can also bend things such as mud and metal, which are only part earth, I believe we can say rather confidently that the presence of the protein isn’t going to stop an earthbender from bending the bone, though they would probably need to be more fine-tuned to the earth, like metalbenders, in order to bend it.
I would say bones would be between earth and metal for ease of bending, not as simple as bending regular earth, but not at all as difficult as bending metal.
So, yeah, I would say a subset of earthbending being, like, Bonebending would not be much of a stretch, though I feel it would definitely be put up with bloodbending in terms of, like, how bad it is (at least when used against someone else), since bones take forever to heal and broken ones are awful. On the other hand, could be used for healing broken bones? That could be very useful, especially since bones take so long to heal.
The answer to your question, then, is yes.
Toph, of all people, would be able to bend bones, and therefore teeth, most likely with relative ease, and therefore would be “some sort of freak toothbender.”
This might be one of the worst asks I’ve ever gotten.
Thank you, Reina.
