A narwhal has no teeth in his/her mouth. The tusk is the only tooth. See attached link from the Polar Science Center.

Yes they do have. The Narwhal (meaning "corpse whale" in Old Norse) is a rarely seen Arctic whale. This social whale is known for the very long tooth that males have.
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.
The genus Monodon includes the beluga whale and the narwhal. They are characterized by their lack of a dorsal fin, rounded bodies, and specialized teeth - the beluga has peg-like teeth while the narwhal has a long, spiral tusk. They inhabit cold Arctic and sub-Arctic waters.
The genetic code for the formation of the narwhal tusk involves a complex interaction of various genes and regulatory elements that control the development of specialized teeth in the narwhal. Specific genes involved in tusk development have not been fully identified and characterized yet.
The Narwhal has a curve in its mouth making it appear to smile all the time. The Narwhal has a large tusk that made reminded sailors of the mystical Unicorns.
The land mammal with the fewest teeth is the armadillo. It has just a few peg-like molars. However, apart from some mammals which have no teeth at all (such as anteaters, echidnas and platypuses), the mammal with the fewest teeth is the narwhal. A marine mammal, the narwhal has just two teeth. These teeth are not inside the narwhal's mouths, but are buried in their upper jaws in both males and females. Only one tooth is visible, and that is the left tooth of the male, which can grow to around 2.4 metres.
A curiosity and a source of amazement are what I think of a narwhal. It's curious how a narwhal looks, what with its frontwards projecting tusk that really is one of two teeth. That tusk may be a reason for its survival and for its decline. For example, the tusk may help a narwhal navigate ocean waters. At the same time, the tusk lures hunters in search of fortune. Also, it's amazing how a narwhal adapts to a challenging environment. For example, a narwhal calls Arctic waters home. Its coloring apes and therefore blends in with the play of light and shadow in the Arctic Ocean's upper waters.
