Content: Unlike human teeth, the narwhal’s tusk is built from the inside out. It is soft on the outside and gradually gets hard and dense on the inside. This makes them the opposite of our teeth. On the surface of the tusk are millions of holes. We also have these holes in our teeth, which make them sensitive to cold food or drinks. However, our teeth are covered with hard enamel. The tusk of a narwhal is sensitive, and scientists believe this would be similar to having your nerves exposed. Since narwhals live in the Arctic, these nerves are always exposed to these icy waters. Where Does The Horn Of A Narwhal Come From? The narwhal horn is actually the left canine tooth that protrudes from the head of a male.
