We’ve shared lots of information on the human mouth, but what about the teeth of our furry friends? Animals have an incredible dental anatomy, ranging in different shapes and sizes depending on what species they are and what sort of diet they consume. The list of interesting facts about animal teeth is seemingly endless, but here are a few of our favorites:
- They Have Few to No Cavities
The majority of animals have a diet extraordinarily low in sugar, especially in comparison to the diets of humans, making them much less likely to develop cavities in their lifetime. In addition, they also chew on much harder material than we do on a regular basis, which helps polish their teeth and keep their mouths free of debris. Those with the highest risk of cavities are domesticated animals; as people have a tendency of sneaking their household pet a treat off of their own plates every now and then (or every meal). So if you want to keep your furry friends teeth healthy, hold the human treats and reach for a bone instead!
- Hippopotamuses Have the Longest Canine Teeth
They may be cute and cuddly on the outside, but don’t let their looks deceive you. They can reach amazing speeds on land and in water, are extraordinarily territorial and aggressive, and sport a set of canine teeth that can grow up to 3 feet in length. Being known as one of the most dangerous animals in the world, Hippopotamuses are not animals to be messed with.
- The Largest Mammal in the World Has No Teeth!
The largest mammal in the world has been awarded to the oceans gentle giant, the Blue Whale. Growing up to lengths of up to 30 meters, weighing up to 140,000 kg, and possessing a heart the size of a small vehicle, the Blue Whale is no small marine mammal. But, despite its overwhelming size and stature, it doesn’t have any teeth! The Blue Whales diet consists mainly of krill. They feed on these small shrimp by swallowing them whole, leaving them with no need for a set of teeth for chewing.
- Snails Have a Remarkable Amount of Teeth
Even though they don’t look like much, the snail does not fall short in the tooth department. Snails, both land and water breeds, have a remarkable set of 25,000 teeth in over 120 rows along the span of their tongue. These teeth, though only visible through a microscope, have been found to be stronger than most spider silks. Crazy, right?
- A Dolphins Age can be Determined by its Teeth
Dolphins have rings on their teeth that develop from the growth that occurs throughout their lifetime. Since Dolphins can only grow one set during their lifespan, their age can be determined by counting the amount of rings found on their teeth, just like a tree!
- Giraffes Have the Same Amount of Teeth as Humans
Giraffes have a full set of 32 teeth just like humans, but despite us having the same amount of teeth as them there are still many differences. Giraffes have no upper front teeth. The majority of their teeth are actually found in the back of their mouths, so they use their long tongues and lips to grab onto leaves and sticks and then send this foliage to the back of their mouth for chewing and digestion.
