Ever looked at a pig and wondered what’s actually going on inside that snout? Most folks just see a pink, mud-loving snout or a source of breakfast. But honestly, if you’ve ever had to handle a pig or work on a farm, you know their mouths are serious business.
Yes, pigs have teeth. A lot of them.
In fact, a fully grown adult pig usually packs 44 teeth into that jaw. That’s significantly more than the 32 humans have. They aren't just for show, either. Domestic pigs and their wild cousins are omnivores. They need a versatile toolkit to crunch through everything from roots and acorns to the occasional unlucky insect or small rodent. If you’re raising them, understanding these teeth isn’t just some weird trivia—it’s actually a massive part of their health and your safety.
The Wild Reality of Pig Teeth
When we talk about whether pigs have teeth, we have to distinguish between the cute Hampshire pig at the county fair and a feral hog deep in the brush. They have the same dental blueprint, but the "tusks" are where things get wild.
Pigs are diphyodonts. Just like us, they start with "milk teeth" and eventually swap them out for a permanent set. But unlike us, some of their teeth never stop growing. Their canines—specifically in boars—are basically biological steak knives. These tusks grow continuously throughout the animal's life.
It’s actually kinda terrifying.
The upper and lower tusks rub against each other every time the pig closes its mouth. This friction acts like a whetstone. It sharpens the teeth into literal razors. In the wild, this is for defense and fighting for dominance. On a farm, it’s a liability. Most farmers end up "nipping" or trimming these tusks to prevent the animals from accidentally (or intentionally) slicing up their pen-mates or their owners.
The Breakdown of the 44
If you were brave enough to count them, here is what you'd find in a mature hog. They have twelve incisors right at the front for nipping and grasping. Then come the four canines—the tusks we just talked about. Behind those, you’ve got sixteen premolars and twelve molars.
The molars are flat and heavy. They’re designed for grinding. Think about the texture of corn, soy, or tough roots. Without those heavy-duty grinders, the pig’s digestive system wouldn’t stand a chance. It’s all about surface area. The more they can grind that feed down, the better they absorb the nutrients.
Why Piglets Are Born "Armed"
Here is something most people don't know: piglets are born with teeth already poking through the gums. These are called "needle teeth."
There are eight of them. They are sharp. Really sharp.
Why? Because nature is competitive. In a large litter, piglets fight for the best teats. Those little needle teeth are used to bite siblings to secure a better feeding spot. It’s brutal. Many producers choose to clip these teeth shortly after birth because the piglets end up scarring the sow’s udder or causing infections. If the sow is in pain, she might jump up and accidentally crush a piglet, or she might stop letting them nurse altogether.
It's a controversial practice in some circles. Animal welfare groups often push for better management instead of clipping, but in high-density farming, those teeth cause real damage. It’s a delicate balance between animal comfort and injury prevention.
Dental Problems You Didn't Know Pigs Had
Just like you might need a root canal, pigs can suffer from dental decay and gum disease. But they can’t exactly tell you when they have a toothache. They just stop eating.
In the world of swine medicine, dental health is often overlooked until it becomes a crisis. A pig with a broken molar or an abscessed gum will lose weight fast. Their coat gets dull. They get cranky. Vet experts like those at the AASV (American Association of Swine Veterinarians) emphasize that "quidding"—where a pig drops partially chewed food out of its mouth—is a huge red flag.
If you see a pig doing that, its teeth are failing.
The Impact of Diet on Wear
What a pig eats changes how its teeth wear down. Pigs in a natural forest environment spend hours "rooting." They push their snouts into the soil and grind against rocks and dirt. This naturally wears down those ever-growing tusks to some degree.
Compare that to a pet "miniature" pig living in a suburban living room. These indoor pigs aren't rooting in the dirt. They’re eating soft pellets and Cheerios. Their teeth don’t wear down naturally. This leads to overgrown canines that can actually grow so long they pierce the pig’s own lip or cheek.
If you own a potbellied pig, you’re basically a dental hygienist by proxy. You have to monitor those tusks.
Common Misconceptions About "Mini" Pig Teeth
There is this huge myth that "Teacup" or "Mini" pigs don't get big tusks.
That is 100% false.
Genetically, a mini pig is still a pig. They have the same 44 teeth. Even the females have canines, though they usually don't grow into the massive, protruding tusks seen in boars. However, an intact male "mini" pig will absolutely grow dangerous tusks. Neutering a male pig early can slow down the growth of these tusks, but it won't stop it entirely.

Honestly, if you’re getting a pet pig because you think they’re "basically dogs," the dental situation will be a wake-up call. Dogs don't have teeth that grow forever. Pigs do.
How to Manage Pig Teeth Safely
If you’re actually dealing with pigs, you need a plan. You can’t just reach in there. A pig’s jaw strength is immense. They can crush bone.
- Regular Inspections: For pet owners, get your pig used to you touching its snout early on. Flip the lip. Check for redness.
- Tusk Trimming: This should usually be done by a vet or an experienced handler using OB wire (obstetrical saw wire). It’s like a thin, abrasive wire that saws through the tusk cleanly. It’s not painful if done correctly because they’re cutting above the "pulp" or nerve line.
- Proper Nutrition: Provide "enrichment" objects. If they can’t root in the woods, give them a rooting box filled with large smooth stones. It helps satisfy the urge and provides some minor dental wear.
- Watch the Sugar: Seriously. Pigs love sweets, but fruit-heavy diets cause cavities just like they do in kids. Keep the treats to a minimum.
Managing pig teeth is basically about being proactive. Once a pig has a massive abscess or a shattered tusk, the sedation and surgery costs are astronomical. It’s way cheaper to keep an eye on things from the start.
Pigs are incredibly intelligent, but they are also "prey" animals by instinct, meaning they hide pain well. By the time they show you they have a tooth problem, they’ve probably been hurting for weeks. Check the mouth. Watch how they chew. It makes all the difference in their lifespan and their temperament.
