As I recall last year's as part of the Tikiween event one of the rewards were Vampire Teeth, and when they first came out some people complained that you couldn't see the teeth (as most of the time, like IRL, our mouths are closed)... But LKWD decided to change them any way and made them so they stick out of your mouth even when closed, and frankly I think they look silly that way:
Regardless, now for those that got the teeth from 2012 and now these new ones, you can pick which style of teeth you prefer - those that stay inside your mouth (2013) and those that poke out (2012).
As others have said, if you use the new teeth, just start texting or use R1 animations, like the Yawn, and you'll see the vampire teeth are in fact 'working'.

"Like it never happened"
- Stand for something better than mediocrity and don't disguise it as adequate, when clearly it is far from that to anyone willing to be objective and unbiased. -
The only way you'll be able to see them is when your avatar's mouth is open and moving. That's how all teeth items seem to work.
