Beaver Teeth: What Do They Look Like & Why Are They Orange?

Beavers are extraordinary animals with many unique features, including their teeth. Have you ever wondered what makes beaver teeth so special?

In this blog post, we’ll take a closer look at beaver teeth and explore some of the reasons why they are so unique.

We’ll also discuss how beavers use their teeth to help them thrive in their environment.

Beaver Teeth Facts

Beaver teeth are incredibly strong and sharp. The enamel on beaver teeth is much thicker than the enamel on human teeth, about twice as thick.

Here are some incredible facts about beavers’ teeth:

  • The combination of strong dentine and thick enamel makes beaver teeth resistant to wear and tear. 
  • Beaver teeth can withstand a force of up to 150 pounds per square inch.
  • They use their teeth to gnaw through bark and wood.
  • Beavers’ teeth are orange because of their enamel, which contains iron.

What Do Beaver Teeth Look Like?

Beavers have large, orange teeth, that they use to fell trees. Their teeth appear orange due to a special coating. They have sharp front teeth for felling, while their back teeth are flat to grind plants.

Beavers’ teeth are specially adapted for gnawing through tough materials like wood. 

Beavers’ front teeth are so large and wide that they can grow up to 2.5 inches (6 cm) long. The back teeth are much smaller and help beavers grind their food.

Their teeth are orange in color and have a hard, enamel coating. This helps to protect them from wear and tear. Their teeth continually grow, so they have to chew on wood to grind them down. This keeps their teeth sharp.

Why Do Beavers Have Orange Teeth?

Beavers are well known for their large teeth. But did you know that beaver teeth are actually orange?

Beavers’ teeth are orange because of the iron-rich protective enamel on their teeth. This enamel keeps their teeth safe from excessive tear, and gives them an orange look, like rusted iron.

What Are Beaver Teeth Made Of?

Beavers’ teeth are made of dentin and enamel. The dentin covers the rear of their teeth, while the front is covered with enamel. The enamel makes them strong, as this consists of iron compounds.

Beavers’ teeth are made of dentin and enamel, the latter containing iron.

Enamel is the hardest substance in the animal kingdom, and it’s what gives beaver teeth their strength and sharpness[1]. Human teeth are also made of enamel, but our enamel isn’t as strong as beaver enamel. That’s because beavers have a higher concentration of minerals in their teeth, which makes them harder and stronger.

The enamel is also what makes their teeth orange: the iron turns into a rusty orange color after sitting in the teeth for so long.

Beavers use their teeth for two main purposes: to build their homes, and to defend themselves. 

Beavers build their homes, called “lodges”, by cutting down trees and logs with their teeth. They then use these same logs and branches to construct their lodge walls. 

They will also use their sharp teeth to defend themselves against predators.

How Many Teeth Do Beavers Have?

Beavers have twenty teeth. All of their teeth grow continuously throughout their lifetime. Beavers use their teeth for gnawing on wood, which they do to build their homes and dams. 

The front half of a beaver’s mouth is filled with large, chiseled teeth that are great for chewing through tough materials like tree bark. The back half of their mouth contains smaller, sharp teeth that they use for slicing and cutting.

Beavers’ teeth are adapted to their diet and lifestyle. The enamel on their teeth is very thick, which helps protect them from the wear and tear of gnawing on wood all day long. 

The shape of their teeth also helps them to be efficient at cutting and chewing.

How Big Are Beavers’ Front Teeth?

Beavers have some of the biggest teeth in the animal kingdom. Their upper incisors (front teeth) can grow up to 1in (25mm) in length. That’s about the same size as a human thumbnail!

The front teeth of a beaver are so big that they protrude out of their mouths, even when their mouths are closed. 

This can make beavers look a bit silly, but it’s actually a very efficient way for them to keep their teeth sharp.

How Long Are Beavers’ Teeth?

Beavers’ teeth are some of the most interesting teeth in the animal kingdom. They use their teeth to cut down trees and build their homes. For that, they need to be long and strong.

Beavers’ teeth are not all the same length. The upper incisors are long, measuring anywhere from 20 to 25 mm. The lower incisors are much shorter, only reaching about 10 mm in length.

So, why the difference? It comes down to how beavers use their teeth. 

The long upper incisors are perfect for cutting through tough tree bark. The shorter lower incisors are used for finer work, like gnawing on smaller branches.

How Strong Are Beavers’ Teeth?

Beavers have some of the strongest teeth on the planet because of the iron in them. This iron makes their teeth tough, durable, and resistant to tooth decay. They are so strong that they can fell trees more than ten feet tall.

Beavers’ teeth are powerful and tough due to the presence of iron, which also gives their teeth their orange color[2]. Beaver teeth must be able to withstand a great deal of wear and tear in order to chew through entire trees. 

The strength of beaver teeth allows them to cut through tree trunks with ease, making them an important tool in the beaver’s survival.

Their strong teeth are also essential for the survival of the species. They use their teeth to build dams and lodges, which provide them with shelter and protection from predators. Beavers also use their teeth to create channels and canals, which help them to move around their wetland habitat.

Without their strong teeth, beavers would not be able to survive in the wild. The strength of beaver teeth is a testament to the amazing adaptability of this species.

Do Beavers’ Teeth Keep Growing?

Yes, beavers’ teeth continue to grow throughout their lives, but daily use helps keep them in check. Their teeth wear unevenly because the softer dentine (bony tissue that forms a tooth) wears away faster than the enamel. 

This shapes the incisors, allowing beavers to cut through hard objects like wood.

What Is the Longest Beaver Teeth?

The incisor teeth of giant beavers, known as Castoroides, were approximately 8 to 9 feet long[3]

These animals were common in North America during the Pleistocene epoch, and their fossils have been found in many parts of the continent. 

Giant beavers were much larger than their modern relatives, and they had longer, sharper teeth that were better suited for cutting down trees.


Beaver teeth are so strong that they helped them survive for millions of years. Their teeth are so tough that they can gnaw through trees and branches to create their dams.

They appear orange because they’re covered in iron. Their enamel (the coating of their teeth) contains iron compounds, making their teeth incredibly tough.
