Hypothetical question about vampires

Postby eugene2k » Mon Jul 28, 2014 2:30 pm

Vampires are a very popular hollywood myth and a lot of paranormal romance books describe them in one way or another. And of course there are a lot of different descriptions about humans transforming into vampires. Eye color changes (vampires even get glowing eyes), they gain weaknesses such as burning in the sun and super-abilities such as superspeed and superstrength. But while all of the above can be more or less explained by a viral infection (as it usually is when the book or movie is trying to explain the existence of a vampire through science) the one thing that in my opinion is hard to explain is the existence of vampire fangs. Obviously, humans only develop two sets of teeth throughout their lifetimes, and teeth can't change their size or shape, unless you somehow expose the odontoblasts that are hidden by dentin and tooth enamel. As such I can only think of one way for a vampire to develop fangs and it seems kind of messy to me: the environment in the mouth would have to temporarily become acidic so that enamel and dentin could be dissolved (which would dissolve all of the subject's teeth and not just the fangs) and then the environment would return to normal and odontoblasts would be able to build new teeth. Couple that with a change in the DNA of odontoblasts and the new teeth would become fangs.

Now, my knowledge in the field of biology is about highschool level, so if I'm missing something please point it out gently (and whatever you do, don't hit the face) and if there is any other way, I would be grateful if you could share it with me.

How about there's just accelerated tooth growth, and this forces the vampire to file down his teeth himself. They sharpen them either because they want to avoid the nerve endings deep within the tooth, or because it's convenient for blood sucking, or both.

How about there's just multiple tooth development, and this causes the creature of the night to computer file down his tooth himself. They improve them either because they want to avoid the sensors being strong within the tooth, or because it's practical for blood slurping.
