In Age Of Ultron we witnessed Hulk lose a tooth.
My question is: Has Bruce Banner lost a tooth as well?
Even with insanely rapid regenerative abilities, I wouldn't think Hulk would regenerate a tooth, seeing as how it's pretty safe to assume that Bruce Banner most likely has all of his adult teeth in his mouth. So why would Hulk grow a tooth back if there is nothing to repair because teeth fall out and that just sucks? I guess his gums would heal instantly. But a tooth? It's not like a chipped tooth would eventually come back to being a full tooth if given time. It just doesn't. So his just wouldn't. Of course I'm speculating since Marvel has yet to publish the The Hulk's orthopedic medical records. But it seems a more logical guess that a regenerative ability would only benefit the body when there's something for the body to regenerate.
