Interesting Facts About Animal Teeth

There are many intriguing peculiarities in the animal kingdom. Imagine an odd new quirk or a strange new plume. As an illustration, consider the pygmy short-horned lizard. It can shoot blood out of its eyes to ward off predators. Another example is the snub-nosed monkey, which always sneezes to let the rainwater out of its nose. But did you know that this uniqueness extends to their teeth? These animal teeth facts can surely attest to it.

1.Tusks are teeth. Here’s a fact that your child might find interesting. Have you ever wondered why some animals have tusks? Or why do they grow them? Tusks are elongated front teeth. Another interesting fact is that they have long teeth that continue to grow.

Teeth in humans stop growing at a certain point. After all, more prominent teeth aren’t necessary for a human mouth. However, in animals that develop tusks, these elongated teeth play an essential role in their daily lives. A tusk is a multipurpose tool for those who wield it, whether for foraging food or protection.

2. Horse teeth continue to grow throughout their lifetime. Horse teeth are examples of teeth that continue to grow. Horses are herbivores that eat mostly grass and hay. One can imagine that their teeth are suffering due to their constant chewing. 

Fortunately, as a horse’s teeth grow continuously, any enamel that wears out and erodes gets replaced. The same goes for animals with similar eating habits, such as rodents and zebras.

3. Sharks don’t get cavities. Shark teeth are one of the most well-known sets in the animal kingdom, frequently appearing in horror films. Take away the fear factor, and you might start to admire those pearly whites. Sharks may even have “the healthiest teeth in the animal kingdom,” according to the Smithsonian. Shark teeth contain fluoride, which makes them extra resistant to cavities. They also lose and replace their teeth every week, so that you won’t see any holes in a shark’s teeth anytime soon. 

4. Dog saliva has a high pH value. You might discover that your dog is more resistant to cavities than you are, much like sharks. Their saliva holds the key. Dog saliva is less acidic than human saliva, neutralizing any acid assaults that oral bacteria may experience. Just ensure that your dog doesn’t consume an excessive amount of sugar. If you give your dog too much of it, the acids can overwhelm the basic pH.

5. Snails have more teeth than you think. Although it may seem weird, snails have teeth. More than any other animal combined, snails have more than 25,000. In addition, they regularly lose and regrow their teeth, just like sharks. But why do snails have so many teeth in the first place? The answer might lie with their seaward brethren. Usually found clinging to rocks, marine snails must break down any extra rock that can get in the way of their feeding to get the food they need. Fortunately, they can do so because of their tooth-filled “tongue” (a radula).

6. Humans and giraffes have the same number of teeth. It may not be easy to accept this little fact, but it is true. However, we can see why you would find it difficult to see their teeth because they are at the rear of their mouths. Instead of grabbing their food with their teeth, giraffes drag it deeper into their mouths with their tongues and lips. 

7. A poisonous snake’s fangs are hollow. We all know that poisonous snakes bite their prey to release venom. But where does the poison come from? It comes from their fangs. A venomous snake’s fangs are hollow, not the same structure filled with dentin and pulp. These teeth join the venom glands, which release the poison that the snakes need to kill or paralyze their prey. However, remember that not all snake bites are poisonous. The term “dry bite” refers to when a snake bites but does not inject venom.

8. Baleen whales don’t have “teeth” but have plates made of keratin. You may remember the large whale with the brush-like mouth that swallows Marlin and Dory if you’ve seen Finding Nemo. That is a baleen whale, and instead of teeth, they have plates that resemble fringes and sweep up food. After all, they don’t need teeth to eat. Instead, they eat tiny shrimp as well as any unfortunate marine creature that manages to get tangled in their fringes. 

9. Beavers have orange teeth. Have you ever looked closely at a beaver’s teeth? They may appear orange. Because their tooth enamel contains iron, they can chew through the bark. 

10. Dolphins use their teeth differently. Dolphins do not need teeth, which is surprising considering their prominence. However, it is useful when capturing prey or using their echolocation systems.

Facts about Animal Teeth:

  • Giraffes, the tallest living terrestrial animals, have only bottom teeth. Another surprising fact about giraffe teeth is that they have the same number as humans (32). 
  • Birds lack teeth, so they must swallow stones or grits to break up hard food.
  • The Egyptian plover is known as the crocodile bird because it cleans the teeth of crocodiles.
  • Pigs have 44 teeth, while armadillos have 104. This is because different animals have a different number of teeth. 
  • However, other animals do not have teeth. The size of the animal does not depend on the number of its teeth. Aside from birds, the most massive creature on Earth, the blue whale, lacks teeth which may not be a big concern as its diet consists of tiny shrimp.
  • The tusk of the narwhal is essentially a giant tooth.
  • Snails have a remarkable number of teeth for such tiny organisms, considering that their mouths are no bigger than a pin’s head. Snails have more than 25,000 teeth.
  • Human teeth cannot regenerate and grow new when permanent teeth are broken. However, elephants can develop new molars six times a lifetime. But on the other hand, this molar can grow up to seven square inches and weigh more than six pounds.
  • Frogs have teeth, whereas toads have not, which is another method to tell them apart.
  • Dolphins only have one set of 250 teeth in their entire lifespan.
  • Want to know more about dolphin teeth? They have an additional protective layer over their teeth to toughen them as they age. Because of this layer, you can see the dolphin’s age by counting the rings of their protective tooth layer.
  • Humans lose their baby teeth during various times of childhood. On the other hand, bunnies lose their baby teeth while inside the womb. 

More Crazy Animal Teeth Facts:

  • Mosquitoes have 47 teeth.
  • Sharks lose their teeth each week but replace them with new teeth. 
  • Tyrannosauruses had 60 teeth that could reach a length of nine inches. 
  • Herbivores like cows and sheep do not have incisors. Instead, they use their lips to cut plants.
  • Komodo dragons have a high count of oral bacteria. As a result, they easily infect their enemies with their sharp teeth.
  • Turtles do not have teeth. However, this was not always the case since they originally had teeth, specifically during the prehistoric era.
  • Spiders do not have a complete set of teeth. Instead, these insects have fangs.
  • Chimpanzees have the same number of teeth (32) as humans.
  • A horse‘s teeth weigh more than its brain.
  • Dogs‘ saliva has a high pH, making them less prone to cavities. Still, a man’s best friend can suffer from oral-related issues without proper care.
  • Kittens have 26 very sharp milk teeth replaced within six months by 30 adult teeth, consisting of two upper molars, six upper premolars, two upper canines, and six upper incisors.
  • Rats‘ teeth are constantly growing. As a result, they must gnaw to reshape and reduce the size of their teeth.

Trivia time is not yet over! When animals’ teeth are healthy, they are more inclined to be more energetic and happier. So how can you tell if the animal is happy? Like humans, a laugh can be a good indicator of an animal’s happiness.

But the real question is, do animals laugh? The answer is yes. How? Well, animals can laugh in various ways.

Here Are The Various Ways Animals Laugh


When these long-tailed, medium-sized rodents laugh, they make chirping sounds, which you can usually hear when they play or tickle. Another interesting fact about rats is that they prefer to be around rats who chirp more frequently because they perceive them to be more fun and positive.


Dogs laugh with forced breathy sounds; thus, the most excellent time to get them to laugh is during playtime.

Chimpanzees And Gorillas

Despite being thought of as our closest relatives, chimpanzees and gorillas laugh more like dogs than humans. Therefore, if chimpanzees and gorillas are teased, wrestled, or played with, you can hear your breathy laughter.


Meanwhile, birds are said to mimic the sound of human laughter by laughing with their heads thrown back. Some people believe that a bird’s laughter expresses territoriality rather than happiness.
