Yes, but depends on the species, just like it does in salt water fish. Just because you can't see a fishes teeth doesnt mean it doesnt have any. Many fish have what are called phyringial teeth, which means they are set further back in their mouths/throat. Carp are a good example of a fish having this sort of dental arrangement. Good examples of Freshwater Fish with prominent teeth are piranah's, gar, pike etc!
