Do Geese Have Teeth? Interesting Facts

Everyone who keeps geese will notice that these birds have teeth-like structures in their mouths and tongues. That’s weird because all birds, including geese, shouldn’t have teeth. That makes many people believe that geese are the only birds on the planet with teeth.

Although geese may appear to be having teeth, their teeth aren’t real, as most of us geese keepers think. The teeth in these birds are fake because they don’t have the enamel or the protective layer covering mammals’ teeth.

Therefore, geese don’t have teeth like mammals, including humans. These birds have teeth-like structures along the edges of their beaks, but not real teeth.

Do Geese Have Real Teeth?

No, geese don’t have real teeth. The teeth-like structures on the edges of their beaks and tongues aren’t real teeth. They are long, saw-like teeth rows known as tomia, and they don’t have enamels like the ordinary teeth in humans and various mammals.

Therefore, the tomia in geese aren’t as hard and sturdy as human teeth because they lack enamel. Nonetheless, that doesn’t suggest they are pulpy or soft. Tomia is extremely sharp and adapted for tearing and cutting.

They work like the teeth in humans and other mammals. However, tomia don’t chew but tear and cut the food into pieces when a goose is feeding. Because tomia are sharp and hard structures, they enable geese to draw blood once they bite prey.

Because geese feed on tough grains, aquatic vegetation, fish, and small mammals, these birds’ tomia help them grip and tear their food before swallowing.

Why do Geese Have Fake Teeth?

Most scientists believe that the geese species roaming the planet hundreds of millions of years ago had real teeth capable of tearing large prey. Today’s wild and domestic geese have teeth, although not as large as those of their ancient counterparts. While geese may appear to have real teeth, their teeth are fake because of a couple of things.

One reason geese’s teeth are fake is that the teeth in these birds don’t have enamel, or rather the protective layer covering the mammals’ teeth. Instead of geese having real teeth, they have hard, spiky cartilages that lack enamels.

These spiky teeth-like cartilages appear and function similarly to the mammals’ teeth. The cartilages are known as tomia, a growth extending from the birds’ beaks. That’s why if you look at your geese’s teeth closely, you will notice the teeth are just cartilages without enamels.

The other thing that makes geese’s teeth fake is that they aren’t suited for chewing, unlike human teeth. They are fit for cutting and tearing prey before the birds can swallow the prey into their crops.

Although their teeth are fake compared to human teeth, that doesn’t mean they can’t bite. These teeth can inflict sharp bites into an enemy’s body, leaving the enemy with severe injuries.

Geese’s teeth are fake because they are all uniform. Other mammals, including humans, have different sets of teeth in their mouths. For instance, mammals have molars, premolars, and canines.

Each tooth type has different functions in an animal’s feeding habits. For example, carnivores use their canines to tear flesh. Geese’s teeth are all the same, and they play the same role, tearing the foods these birds eat into smaller, digestible portions.

Why Do Geese Have Teeth on Their Tongues?

If you open your goose’s mouth and check its tongue, you will notice saw-like rows of teeth on the tongue. As weird as it seems, these saw-like teeth structures play a crucial role in geese’ feeding habits since the birds won’t normally feed without the saw-like teeth structures on their tongues.

Because geese feed on tough grasses, roots, stems, and animals, the teeth on their tongues assist the birds in tearing off their food. Otherwise, geese won’t tear their food if they don’t have teeth on their tongues.

The other huge benefit of geese having teeth on their tongues is that the teeth in these birds help them hold onto their prey while feeding, making the prey unable to escape. Geese feed on various live prey, including fish and smaller mammals; therefore, these birds need to hold the prey when feeding lest it runs.

Do Geese Chew Their Food?

No, geese can’t chew their food despite having teeth-like structures along the edges of their mouths and tongues. In these birds, the tomia, teeth-like structures are suited for tearing foods rather than chewing or grinding various foods.

Furthermore, the tomia help geese hold on to their food when feeding. Otherwise, the birds won’t hold their food in their mouths if they don’t have teeth. Geese will rely on their teeth to tear food, but they won’t chew the food before swallowing because their teeth aren’t suitable for chewing.

Geese’ feeding habits are similar to those of other bird species, whereby the birds swallow down food without chewing.

Does Goose Bite Hurt?

Yes, it does. A goose bite can be pretty painful because the tomia in these birds are quite sharp. The tomia consist of bone-hard material that geese depend on to attack their targets and feed. Therefore, a goose bite can hurt, considering geese’s teeth are extremely sharp and suited for tearing things.

A goose bite can leave you with nasty bruises and wounds, especially if several geese attack you at once. Therefore you shouldn’t get too close to aggressive geese because the birds will bite you, particularly if they see you to be a threat to their goslings or eggs. There are over 60,000 cases of goose bites in America every year.


Geese have teeth, unlike other bird species, but not real teeth. Moreover, wild and domestic geese’s teeth are suited for tearing their food rather than chewing food. Geese can’t live without their teeth because the teeth help them feed on the hard vegetation, seeds, and roots that make up their diet.

Therefore, it is normal for geese to have teeth, unlike other birds, although their teeth are fake compared to human teeth. Furthermore, geese are exceptional because they are the only creatures with teeth on their tongues.
