Teeth are not bones
Teeth have a coating called enamel (the hardest substance in the human body), are made of dentin underneath, and have a pulp full of nerves and blood vessels on the inside. Bones, by contrast, have fatty marrow and/or something called “spongy bone” on the inside, and the outside of the bone is coated in a membrane. Bone is full of collagen and blood vessels; the hard parts of teeth have neither.
Some idiot didn't get the science facts right, there is a DOMINANCE of one nostril, and it shifts every couple of hours to another one, but it sure is not 100% one nostril, in normal circumstances.
