There is something about Wolverine’s skeleton that fans often overlook. His adamantium reinforces his bones, but his teeth are not simply another set of metal-coated bones. Teeth have a different structure, including enamel, dentin, and roots. That raises an interesting question about how his healing factor works. If Wolverine can survive devastating injuries and regenerate damaged tissue, why would his teeth still behave like ordinary teeth instead of becoming part of the same indestructible system? The answer depends on the limits of his mutation, not just the fact that adamantium is bonded to his skeleton.

Peter Parker keeps losing the things that make his ordinary life worth living, and people still treat his struggles as if they are just part of being Spider-Man. That is what separates him from many other superheroes. Tony Stark can rely on his resources. Thor has lived for centuries. Peter is a young man who still has to worry about rent, relationships, and whether he can make it through another day without disappointing someone. His greatest weakness has never simply been that he is less powerful than other heroes. It is that saving strangers can mean sacrificing the life he is trying to build for himself.
