Do Ducks have Teeth?

Ducks are beautiful and fascinating animals, and it’s easy to see why so many people love them. If you see them in water, they are like swan-like creatures with long necks and beaks that are always ready to go fishing. You’re maybe one of those people who have seen many ducks in your life, but you never actually paid attention to whether they had teeth. But what about those teeth? Do ducks have teeth? How many teeth do they have?

In this article, you will learn everything you need to know about ducks and their teeth. 

History of Ducks and Their Teeth 

Just like the other species of birds, ducks are fascinating, and we are only beginning to understand all of their secrets. 

Many people keep ducks as pets, but they have been around for much longer. In fact, these birds have been around for over 30 million years! Fossils of ducks have been found dating back to the Cretaceous period, which means that they were around even when dinosaurs roamed the earth.  

Their closest relatives are geese and swans, and two other waterfowl. They all descend from the same ancestor. 

Humans have used their eggs, meat, and feathers for centuries, and some cultures even worshiped them.

So, Do Ducks Have Teeth?  

It’s a common misconception that ducks do not have any teeth. 

In actuality, ducks have teeth-like structures that are called “papillae.” These are very small, keratinized projections that line the inside of a duck’s mouth, and they have 28 to 32 of those. These are tiny and are located on the edges of their bills. Despite the fact that duck teeth are not real teeth, they serve to break up food and prevent it from sliding out of its mouth.   

What are Duck Bills?  

A distinguishing feature of the duck is the “duck bill”. The duck’s bill is flat and often has serrated edges.  This feature has special sensory receptors that enable them to find food and helps them to filter food out of the water.

Although duck bills may look similar, each duck species has a slightly different bill shape adapted to their food as they have a varied diet.

Do ducks chew food with bills? No, they don’t. The slight movement of bills helps ducks swallow food in the whole bites.

Other birds that feed on food from water may have flattened bill shape beaks.

Spatulate Shape   

Some ducks have specialized bill structures. They have spoon-shaped bills, known as spatulate bills. This type of duck’s bill helps with filter-feeding. The duck uses its bill to scoop up water and then sifts through the water to find food. 

Some of the most common species with spatulate bills include: 




Pectinate Shape   

The bills of other ducks are comb-like, known as a pectinate bill. This type of bill is adapted for picking up food from the bottom of a body of water. The pet duck uses its comb-like bill to rake through the mud. 

Some of the most common ducks with pectinate bills include: 




What’s Inside the Duck’s bill 

  • Nail-like Tubercles: The bills of some ducks have tiny, nail-like tubercles. These tubercles help pet ducks grip their food. 
  • Glands: These produce a waxy substance that helps to waterproof the duck’s feathers 
  • Nostrils: These allow her to breathe while underwater 


Ducks also have something called lamellae in their bills. Lamellae are tiny, hairlike structures that help them filter their food. Lamellae are especially helpful for them they eat small aquatic creatures like crustaceans. The lamellae help the duck sift through the water and pick out its food. 

Grin Patch    

The bills of some ducks have patches of bare, fleshy skin called a grin patch. It helps the duck grip its food. The grin patch is beneficial for these birds that eat slippery prey like fish. 

Duck Bristles   

Duckbills also have special sensory receptors that help them to find food. These receptors are called bristles, located around the edges of the duck’s bill. The bristles help detect vibrations in the water, which can indicate the presence of food. 

These are just a few of the adaptations that these birds have developed in order to survive. These adaptations help them find and eat food and avoid being eaten by predators.

Two Classes of Ducks  

Dabbling ducks  

Dabbling ducks are the most common type of duck, and they are often the kind that people think of when they think of ducks. 

These famous birds include species such as mallards, wood ducks, and teals. 

These birds feed by tipping their bodies forward and scooping food off the water’s surface with their bills. These birds usually eat aquatic plants, insects, and small fish. 

Diving ducks

Diving ducks are less common than dabbling ducks, but they are still found in many parts of the world. 

The diving ducks include species such as mergansers and scaups. These birds feed by diving underwater to find food. They usually eat aquatic plants, small fish, and crustaceans. 

Both dabbling and diving ducks are adapted to their respective feeding methods. The former have bills shaped like paddles, which help them scoop food off the water’s surface. While the latter have bills that are shaped like tubes, which allow them to suck in food from the bottom of a pond or lake.

Duck teeth: How to keep them healthy

Duck’s teeth, called beaks, don’t work like ours or most animals. They don’t chew their food but swallow it whole instead.

If you’re thinking of raising ducks or other birds alike, here are some tips to help keep the beak healthy:

1. Keep Their Beak Clean 

Like our teeth, plaque and bacteria can build up on the beak if we don’t brush them regularly. You can clean the beak by gently rubbing it with a wet cloth. 

2. Keep Their Beak Trimmed 

If you notice that the beak is getting too long, you can trim it with a nail file or emery board. But be careful not to cut too much—you don’t want to hurt your duck! 

3. Provide Them with Plenty of Water 

Water is essential for a duck’s health, and it can also help keep its beak clean and healthy. Make sure your duck has access to clean fresh water. 

4. Feed Them a Healthy Diet 

A healthy diet is essential for a duck’s overall health, and it can also help keep its beak healthy. Ducks need a diet that is rich in protein and low in fat. You can give your duck a variety of foods that contains a nutritional value such as vegetables, fruits, grains, and even insects. 

5. Take Them to the Vet 

If you notice anything unusual about the beak of your duck, such as discoloration, cracks, or excessive growth, take them to the Vet. A vet can help diagnose any problems and recommend treatment.
