LOL, Kerry. Sparkly is as sparkly does, I'd say.

As far as I have always known a vampire's fangs retract. They only appear when the vampire is getting ready to bite/feed on someone. At other times they have normal teeth.
Yes, the "modern" version vampires have retractable fangs.... Dracula in Coppola's film, and all the modern TV versions. I haven't seen Edward Cullen and his lot on film, but it's a safe bet he doesn't walk around with incisors down his chin on a daily basis. And the Buffy vamps went from handsome hunks to toothy monsters every time feeding time was nigh, of course.
But somehow I always figured the old-style vampires, the Nosferatu and the original Draculas, walked around (flew around?) with their prominent teeth always on display. And Barlow on "Salem's Lot" seemed one of those old-style Nosferatu types.
Maybe I'm wrong - maybe the old school vamps did have retractable fangs too. Anyone know for sure? Has the retractable feature emerged in modern-day evolution of vampires, or has it always been there?
