Yes that is a pair of teeth growing out of that mountain lions heads and no they do not know why that has happened.

“It is possible that the teeth could be the remnants of a conjoined twin that died in the womb and was absorbed into the other fetus. It is also possible that deformity was a teratoma tumor. These kinds of tumors are composed of tissue from which teeth, hair, and even fingers and toes can develop. They are rare in humans and animals.”
