Because no narwhals have horns! However, both male and female narwhals have tusks. Males are more likely to have two tusks, but you can't necessarily see a narwhal and judge its gender based on its tusk.
It is believed that the horn (Which is actually a tusk, a type of tooth) is used for nothing more than sexual identification. Males are the ones that have the tusk, located on the left incisor, though females can have them on rare occasions. 1 out of every 500 Narwhals has a second tusk on the right incisor, but there has only been one sighting of a female narwhal with two tusks.

A female narwhal does not typically have a tusk, but yet not all males do, either. About 15% of female narwhals have these tusks. The truth is, scientists don't yet know why most males have them, and most females don't. They do, however, know that the so-called "tusk" is really a tooth that has grown through the upper lip. Narwhals only have two teeth. Sometimes both of them will grow through the upper lip, and other times, neither tooth will grow out like this. Scientists are still trying to figure out why that is, and it may take a while, but eventually they will have an answer.
A male narwhal tends to have just one tusk. The tusk grows out from the incisor tooth on the upper left jaw. But there are rare instances of a narwhal having two tusks. The second tusk tends to be a smaller version of the main one. It grows out of the right incisor.
Most narwhals have just the one 'tusk', and it is actually a tooth. One in 500 males have two tusks, but the skull has a double tusk'.
Characteristically, the male narwhal is known for his tusk, which is actually one of his two teeth that happens to jut out beyond the confines of his mouth. There are exceptions; however, to this rule -- there are some female narwhals that also have this tusk, and some male narwhals have two tusks, in which case both teeth are outside the mouth.
Narwhals have teeth. In fact, the male's characteristic tusk is merely the extension of the incisor on the left side of the upper jaw. In rare instances, the male narwhal has two tusks. In such cases, the second, smaller tusk grows out of the incisor on the right side of the upper jaw.
