It looks more like Ren spread the force of his Aura (hinted by the ring) into the snake's head after he shoved its tooth into its eye. That would make much more sense as to why the tooth didn't just shoot straight through. As to why the snake's head exploded, I'd say Ren just poured enough Aura into his attack to overload the snake's head, thus killing it.
