Did You Know?
1. Contrary to popular belief, moles do have teeth! However, their teeth are not conducive to chewing their food. They have sharp, pointy teeth designed for catching and killing their prey, which mainly consists of insects, worms, and small rodents.
2. The teeth of moles are highly specialized and are positioned strategically in their mouths. The front teeth, known as incisors, are elongated and protruding to aid in digging tunnels efficiently. The strong canines are used to immobilize their prey, while the molars located at the back of their mouths help them crush the exoskeletons of insects.
3. Interestingly, moles’ teeth are not stained or colored by iron, as opposed to their fur. This allows the teeth to remain sharp and clean, preventing the buildup of debris that could hinder their hunting abilities.
4. Moles have a remarkable ability to regenerate their teeth throughout their lives. As they continue to wear down due to constant digging, new teeth grow to replace the damaged or worn ones. This constant cycle ensures that moles always have efficient teeth for their underground lifestyle.
5. Moles have an impressive bite force for their size. Despite their small stature, their teeth can exert a pressure of up to 300 pounds per square inch (psi). To put it into perspective, this is around the same bite force as a medium-sized dog!
Introduction To Moles And Their Dental Anatomy
Moles, the small mammals belonging to the family Talpidae, have fascinated scientists and nature enthusiasts. There are around 42 different mole species found across the world, excluding Antarctica and South America. But do moles have teeth?
Contrary to what one might think, moles have a unique set of dental adaptations that help them thrive in their underground habitats. They possess a total of 44 teeth, which includes twelve incisors, four canines, sixteen premolars, and twelve molars. These heterodont teeth, with their diverse sizes and shapes, serve different purposes in a mole’s life.
The Range And Distribution Of Moles
Moles, which are widely distributed, have discernible geographic limitations. Their absence in Antarctica and South America remains a puzzle, leaving us to explore their remarkable adaptability within the rest of the world. Moles inhabit diverse regions, from open grasslands and woodlands to forests and mountains. However, they have a strong affinity for moist soils, making marshes, meadows, and gardens particularly suitable for their subterranean lifestyle.
As we delve deeper into the realm of moles, it becomes clear that their habitat preferences are closely tied to the presence of earthworms, which serve as the primary food source for moles. Earthworms provide the necessary energy and nutrients for the survival of moles. Consequently, the geographical distribution of moles tends to coincide with the availability of earthworm populations, ensuring a continuous supply of sustenance.
The Heterodont Teeth Of Moles And Their Functions
In the realm of dentition, moles exhibit an impressive array of heterodont teeth, each with specific functions suited to their subterranean lifestyle. Let’s embark on an exploration of moles’ remarkable dental anatomy.
Starting with the incisors, moles possess twelve of these long, blade-like teeth. Interestingly, the upper incisors are larger than their lower counterparts. These incisors play a crucial role in tunneling, allowing moles to excavate and navigate through the soil with remarkable precision.
Moving on to the canines, moles possess four of these specialized teeth. However, their arrangement differs from what one might expect. The lower canines are actually larger than the upper canines, which is unique to these enigmatic creatures. These canines, sharp and pointed, serve as formidable weapons during territorial disputes and fights.
As we delve into the premolars, we observe their triangular shape, located near the front of the mouth. These teeth, adorned with sharp points, are essential for moles to chew and grind their food, providing efficient processing of the earthworms, slugs, snails, spiders, grubs, beetles, and larvae that constitute their diet.
Finally, we reach the molars, displaying a remarkable adaptation known as dilambdodont dentition. These teeth possess two “V”-shaped ridges, collectively resembling a “W” shape. The first and second upper molars have double ridges, while the third upper molar showcases an intriguing “N” shaped ridge. These molars are exquisitely designed for cutting and chewing prey, with sharp and pointed points in both the upper and lower molars facilitating efficient food processing.
Dental Characteristics And Adaptations Of Moles
Within the mole family, a distinct genus named Mogera exhibits some peculiar dental characteristics and adaptations. Compared to other moles, Mogera moles possess one less pair of incisor teeth. They also boast larger premolars, with a notable configuration of ten incisors and 42 teeth overall.
What purposes do these adaptations serve? The larger premolars in Mogera moles are believed to enhance their ability to capture and process the invertebrates comprising their diet. These adaptations allow Mogera moles to thrive in specific ecosystems where such adaptations provide a competitive advantage.
Moles primarily utilize their teeth for two critical tasks: eating and fighting. These teeth, carefully crafted by evolution, are equipped to process their subterranean delicacies efficiently. Additionally, during territorial disputes and mate competition, male moles skillfully employ their teeth to assert dominance and secure their position within the complex social hierarchy.
Evolutionary History Of Moles And Oldest Fossil Evidence
To fully understand the unique dental anatomy of moles, one must explore their evolutionary history. These astonishing creatures have been in existence for millions of years, with their early ancestors resembling shrew moles and displaying a more extensive above-ground presence.
Fossil evidence of moles dates back approximately 36 million years, shedding light on their evolution and long-standing existence. These ancient fossils reveal the gradual adaptations and dental modifications honed over time, further solidifying their position as expert subterranean dwellers.
- The intricate teeth of moles serve crucial functions in their quest for survival:
- Tunneling
- Capturing prey
- Engaging in territorial disputes
By understanding and appreciating this unique dental anatomy, we gain a deeper understanding of the fascinating lives led by these subterranean creatures.

Frequently Asked Questions
How many teeth do moles have?
Moles are known for their impressive dental structures, boasting a total of 44 teeth. This includes twelve incisors, four canines, sixteen premolars, and twelve molars. These teeth enable moles to effectively dig through soil and feed on their primary diet of earthworms and insects. With such a robust dental array, moles are well-equipped for their underground lifestyle.
What is a mole tooth?
A mole tooth, in the context of dentistry, refers to a molar tooth that belongs to a mole. Mole teeth are similar to human molars in terms of being rounded and flat, but they vary in size and shape according to the species. These teeth play a crucial role in the mole’s specialized diet and are adapted for digging through soil and consuming earthworms, insects, and plant matter. While often overlooked due to their underground lifestyle, mole teeth are an interesting example of nature’s diverse dental adaptations.
What kind of teeth do moles have?
Moles have a specialized set of teeth that are well-suited for their insectivorous diet. Their long incisors allow them to easily pick insects out of dirt and leaves, while their small but sharply edged canines, pre-molars, and molars aid in chewing hard-shelled beetles, other insects, and worms. These teeth adaptations enable moles to efficiently consume their preferred food sources and thrive in their underground habitats.
What do moles eat?
Moles are fascinating creatures with a diverse appetite. They primarily consume a variety of insects and invertebrates, such as earthworms, centipedes, millipedes, snails, grubs, and ants, among others. However, unlike their North American counterparts, Washington moles also incorporate plants into their diet. This means they may occasionally snack on plant matter, making them somewhat omnivorous in their feeding habits. It is interesting to note the wide range of fare that moles can enjoy, from crawling critters to vegetation, allowing them to adapt and thrive in various environments.
