When vampires Drink, do their teeth get longer? Do vampires have fangs?
In particular, the "Buffy the Vampire Slayer" genre of vampires morph their entire face when they drink blood. When they’re undergoing blood lust, vampires go from their normal human face to their natural demon state – so yellow eyes, ridges around the eyes and nose as well as elongated fangs. In their demon state, vampires are not so pretty anymore. It’s supposed to be a reflection of their lack of soul.

Nope. Most vampire teeth are pretty normal looking. Some may be rather sharp though. Some people have longer teeth than others, but not ‘fangs’ like in the movies. Also, I feel obligated to say that biting is dangerous, it causes bad scaring, and most of us do not bite. Most make small cuts with STERILE objects. (Don’t try this at homes kids. You need to know A LOT about the body before EVER cutting, biting, or otherwise extracting blood.
