If you're asking why player-Khajiit don't have fangs, I would only trust either a loremaster's answer or some source that is in the game.
I've seen depictions where Senche-Raht, Pahmar-Raht, and Senche breeds all have fangs protruding from the mouth, but Caska doesn't appear to have those fangs. There are Saber Cats in the game, so the choice to not give them fangs seems to be intentional (it might have something to do with keeping the verisimilitude of being able to speak the common tongue with such protrusions). There could be lore reasons or technical reasons... it could be an oversight or it could even already be in the game.
