The Mystery of Deer Teeth

In the wild, understanding a creature like a deer goes beyond its graceful leaps and antler size. One of the unsung markers of species identification lies within their mouths – their teeth. There’s a fascinating world to discover in the dental structure of deer, from rare upper canine teeth, commonly known as deer fangs, to the changing count of cheek teeth that can help estimate their age.

Read into this post as we explain more about deer teeth, taking cues from whitetails to mule deer. Whether you’re an animal enthusiast or an eager hunter, this guide will help you decode the dental secrets of our four-legged friends.

Unraveling the Mystery of Deer Teeth

Identifying Characteristics of Deer Teeth

Recognizing the distinct elements of deer teeth can provide valuable insights into their age, diet, and evolutionary history. These herbivores possess a variety, with premolars serving to slice up food and molars used for grinding it down.


Each is encased in enamel, a hard white outer surface, protecting the softer, brown dentine inside. A hollow section in the tooth, called the infundibulum, often retains food residue, and brown tartar staining can be found. The number of cheek teeth can be a key indicator of age; deer under a year generally have fewer than six, while those older possess six.


Rarely, deer, specifically whitetails and mule deer, develop upper canine teeth or fangs. These vestiges from past evolutionary stages were once utilized for protection, mating, and potentially meat consumption. Today, these fangs have largely diminished, with muntjacs being one of the few deer species still sporting both fangs and antlers.

  • Some Mule Deer grow small upper canine teeth or fangs.
  • These fangs can be under ½ an inch and might not protrude from the gum line and historically served for defense and mating in deer.

Other Species

  • Fangs are found in less than 1% of whitetails.
  • Fangs (Upper Canine Teeth) are rare in Mule Deer

Understanding the Function of Deer Fangs

Grasping the role of deer fangs in the animal kingdom is an intriguing journey into evolution. Also referred to as upper canine teeth, these features are uncommon in contemporary deer species.

However, they’re not completely extinct. Existing primarily in whitetails and mule deer, these are usually shorter than ½ an inch.


Their function? Well, they were essentially the weaponry of ancient deer species. Used for defense, mating rituals, and potentially even to consume meat, these fangs were an integral part of their survival toolkit. Today, their role has largely diminished. Still, certain species like muntjacs continue to sport both fangs and antlers.

As far as prevalence goes, less than 1% of whitetails boast upper canines, with a slightly higher percentage in Central American whitetails. Surprisingly, both bucks and does can possess these teeth. However, they’re predominantly observed in bucks, thanks to the popular trend of European skull mounts.

Fascinating Facts about Mule Deer Teeth

Looking further into the intriguing world of mule deer, several captivating facts come to light.

  • A fascinating feature of mule deer is the occasional presence of small upper canine teeth or ‘fangs.’ This is a rare occurrence with these tiny teeth often failing to break through the gumline.
  • Akin to a walk down memory lane, these fangs hark back to a time when deer relied on them for defense and mating rituals.
  • In a quirky twist of evolution, certain modern deer species, like the muntjacs, display both fangs and antlers, a testament to their ancient lineage.
  • Fangs in deer are a rarity, with less than 1% of whitetails boasting upper canines. This rarity can make a deer with fangs a sought-after prize among hunters.
  • Let’s not forget the more common deer teeth, the cheek teeth, used for cutting and grinding food. Their wear and replacement patterns offer clues to a deer’s age.

Antlers Connection

Finally, deer antlers, often a point of fascination, shouldn’t overshadow the story that their teeth tell.

From fangs to cheek teeth, every type tells a tale, contributing to the diverse narrative of the deer species.

Understanding the anatomy and functions of deer teeth can be quite fascinating. From the various types of teeth that each serve a specific role, to the rare and peculiar existence of fangs, these insights reveal the intriguing evolutionary history of deer. By studying the wear and replacement patterns, we can even estimate the age of a deer, which can be an important tool for hunters or wildlife conservationists.

The presence of fangs, although rare, is an intriguing aspect of the deer’s dental structure. These upper canine teeth are a remnant of their evolution and used to serve various functions, including protection and mating. Modern deer species, like the muntjacs, still flaunt both fangs and antlers, showcasing the genetic echoes of their ancestors.

In summary, the realm of deer dentistry is a fascinating blend of biology, evolution, and natural history. Whether it’s the intricate structure of their teeth or the rarity of their fangs, these dental peculiarities paint a captivating picture. The study of deer teeth is a testament to the power of nature’s craftsmanship and an invitation for us to appreciate the incredible diversity of wildlife.
