These have fangs as you can see.

Actually, what you are seeing are cuspids that look pretty much the same as human teeth. You may have been confused by the fact that the lack of adjacent teeth and the missing buccal plate of bone exaggerate their apparent length.

The upper photo clearly shows the Cemento-enamel junction (the diagonal brown line) on the upper right side. The tooth would originally have been anchored in bone almost to this level. The anatomy and profile of this tooth are just like a human.

In the lower image the lack of posterior teeth has allowed the jaws to overclose. This gives the misleading appearance of fangs. Your inexperience in this field has, once again, led you to misinterpret what you are seeing.

And yes, I am a dentist.
