Ever wondered if chipmunks have teeth? Yep, they sure do.
Chipmunks sport sharp, ever-growing front teeth—incisors—that crack open nuts and chew tough food. Those teeth play a huge role in how these little critters survive out in the wild.

Chipmunks also use their cheek teeth to grind up plants, seeds, and sometimes even insects. Since their teeth never stop growing, they have to keep gnawing to wear them down and stay healthy.
Honestly, chipmunks are kind of fascinating when it comes to dental stuff.
Knowing about chipmunk teeth can help you understand their quirky habits. Whether you’re curious about their bite, their diet, or how their teeth work, you’ll find the basics here.
Do Chipmunks Have Teeth? Core Facts

Chipmunks, just like many other rodents, rely on a special set of teeth to get by. Their teeth handle gnawing hard foods like nuts and seeds.
These teeth keep growing all their lives, so chipmunks need to wear them down constantly.
How Many Teeth Do Chipmunks Have?
Surprisingly, chipmunks have between 20 and 22 teeth. The exact number depends on the species, like the eastern chipmunk (Tamias striatus).
Their teeth follow a pattern: incisors up front, no canines, and a mix of premolars and molars.
Here’s a quick breakdown:
| Tooth Type | Number per side (top/bottom) | Total Teeth |
|---|---|---|
| Incisors | 1/1 | 4 |
| Canines | 0/0 | 0 |
| Premolars | 1-2/1 | 4-6 |
| Molars | 3/3 | 12 |
This setup lets chipmunks crack tough shells and grind up their food pretty efficiently.
Types of Teeth and Their Functions
Chipmunks have two main types of teeth, each with its own job. The front teeth, or incisors, stay sharp and never stop growing.
You’ll see chipmunks use these to gnaw on wood or crack open nuts. Their incisors work kind of like chisels, breaking through tough stuff.
Behind a gap called the diastema, chipmunks have cheek teeth—premolars and molars. These grind and chew food so chipmunks can digest nuts, seeds, bugs, and plants.
Since they don’t have canines, their teeth line up perfectly for their mixed diet.
Continuous Growth of Chipmunk Teeth
Chipmunk teeth just keep growing, unlike human teeth. You’ll notice this with other rodents too, like squirrels.
The front incisors grow nonstop to make up for all the gnawing they do.
Chipmunks have to chew on hard things like wood or seeds to keep their teeth from getting too long. If they skip this, their teeth can overgrow and cause problems, like trouble eating or even mouth injuries.
So, they gnaw a lot—it’s just what they do to keep those teeth in check.
Chipmunk Dental Health and Adaptations

Chipmunks have strong teeth that grow all through their lives. They gnaw to keep those teeth sharp and the right length.
These teeth help them crack open tough food and, sometimes, defend themselves.
What Happens If a Chipmunk Breaks or Loses a Tooth?
If a chipmunk breaks or loses a tooth, things can get rough. Since their teeth grow nonstop, damage can make eating hard foods much harder.
A broken front tooth might lead to infections or make gnawing painful. That could stop a chipmunk from eating enough, which honestly puts its health at risk.
They need both their incisors and cheek teeth to chew nuts, seeds, insects, and plants. Losing teeth can cause malnutrition or weakness, making them easier prey for hawks or coyotes.
How Chipmunks Use Their Teeth in the Wild
Chipmunks use their teeth to chew through tough foods—nuts, seeds, sometimes even bird eggs. Their front incisors are sharp and strong, perfect for gnawing and cracking shells.
They’ll also chew wood or even plastic to wear down their teeth. This constant gnawing keeps their teeth short and sharp.
With help from their powerful jaws, chipmunks crush food and enjoy a pretty varied diet. That’s how they stay healthy and ready to dodge predators like hawks or coyotes.
Differences Between Chipmunk and Squirrel Teeth
Chipmunks and squirrels both belong to the rodent family, so honestly, their teeth look pretty similar at first glance.
They’ve each got those long, sharp front teeth that just keep growing. But if you look closer, chipmunks usually have fewer premolars than squirrels do.
Chipmunk teeth work best for handling smaller, tougher foods. These little guys need to gnaw constantly, or else their teeth get way too long.
Squirrels, though, often have bigger teeth. Makes sense, since they like cracking open harder nuts and sometimes even chew on bark.
Both animals use their teeth for chewing and even for defense. But chipmunks seem to depend more on quick, frantic gnawing just to get by.
