You can buy them from the internet, as was recommended to be by Tipster Vampiricelf. I got mine from ebay. They're called 'mould on' fangs and mine were less than £5 inc P+P. They come with two sachets of putty, you mix them together and then half the mixture, put it inside the teeth and press it up onto your canines for five minutes (which is actually quite a long time). Make sure you push it on firmly, and don't wiggle them, otherwise they won't fit as tightly. Trim off the excess dried putty with a knife and presto! removable, realistic vampire fangs you can use again and again. Mine even came in a little coffin box! Brilliant.
