Although it is likely that these fossilized teeth belonged to the dinosaur later identified as Gorgosaurus libratus

Gorgosaurus

Gorgosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, between about 76.5 and 75 million years ago. Fossil remains have been found in the Canadian province of Alberta and possibly the U.S. state of Montana....

, it is virtually impossible to distinguish between different tyrannosaurid species based on tooth characteristics alone, so Deinodon is today considered a nomen dubium
