The fangs were actually a little bit small for my K9s and I didn't like the look of them on my incisors so I fit them for the K9s.  There is a bit of a gap at the top of my tooth because they don't quite reach my gum line and they stick out a bit far from my tooth.  They do look very good if you don't look at my gum line and they are very secure on my teeth.  The smell of the mold is a bit strong but I think if I leave them out the smell will dissipate.  Overall they are a good product and will make a great addition to my Halloween costume
