How Many Teeth Do Porcupines Have?

Porcupines have twenty teeth. This includes four incisors and 16 molars. Like many members of the rodent family, their front two molars never stop growing.
Unlike other rodents, their teeth are bright orange in color. With so many teeth, you would think that these animals would bite when fighting, but they are not known for biting. They do use their teeth in a unique way when they are defending themselves, however.
We will find out how a bit later. Let’s take a deeper look into porcupine teeth and their unusual qualities.
Always Growing

Incisors on a porcupine never stop growing. This could become a problem if the porcupine doesn’t find a way to grind the teeth down to a manageable size. If they become too long, he won’t be able to eat. Being plant-eaters, the food a porcupine eats doesn’t do much in the way of helping to grind the teeth down.
This is why you often find porcupines gnawing on tree bark. In addition to tree bark, porcupines will gnaw on deer antlers that have fallen off in the winter. In addition to helping grind the teeth to a manageable size, the antlers help provide salt and other minerals that the porcupine needs to be healthy.
Porcupines can also be found munching on boat oars and other wooden objects around the camps of humans. They seem to be particularly attracted to things that are covered in human sweat. This is most likely because the sweat contains salt, which is something that all porcupines crave and will actively seek out.
Orange Teeth?

Something that may surprise you if you happen upon a porcupine is that they are bright orange in color. This is because the teeth contain a high amount of iron oxide that makes up the enamel. Not all rodents have this color, but porcupines do share this trait with beavers.
The mineral iron that makes up the enamel allows the coating of the teeth to become stronger than if the coating contained the traditional magnesium that makes up most teeth enamel.… Read the rest of the story.
