Does A Frog Have Teeth – Types & Evolution

Does a frog have teeth? Some have tiny teeth on the top of their mouths and the upper jaws, while others have features resembling fangs. Some species lack any teeth at all. The majority of frogs use their jaw muscles to grip and tear.

Frogs usually feed on soft-bodied insects, worms, and other small invertebrates they can capture with tongues. A few species have been known to eat small fish, mollusks, or even small mammals.

Despite teeth in some species, they play no significant role in feeding habits. Instead, frogs rely on their long sticky tongues to catch food. The combination of teeth and tongue makes them great hunters!

However, not all frogs have these features, as different frog species vary in anatomy. For example, certain types of frogs, such as tree frogs, have a hard ridged beak used for eating instead of teeth or fangs, which are found in some aquatic species.

  • In a nutshell, the answers to the question “Do frogs have teeth?” is yes and no, depending on the type of frog. 
  • Some species possess tiny teeth or ridged beaks, while others lack any form of dentition! Regardless of the presence or absence of teeth, frogs rely mainly on their tongues for capturing prey.

Does A Frog Have Teeth – Types & Evolution

Types Of Frog Teeth


Frogs have the following types of frog teeth:

1. Maxillary:

Frog Maxillary teeth are usually found on the top of the mouth and extend along the upper jawbone. They’re used to hold food in place as a frog eats or swallows it.

2. Vomerine:

Frog Vomerine teeth, which look like fangs, are located at the base of a frog’s jaw and help them capture prey.

3. True Teeth:

Some species of frogs possess true teeth on their upper jaws and the top of the mouth, which are used to grip onto food and tear it apart.

  • Example: Bell’s Dwarf Frog

4. Fang-Like Features: 

Certain species have features resembling fangs, which helps them catch prey more effectively.

  • Example: Red-Eyed Tree Frog

5. Hard Ridges: 

Some frogs, such as tree frogs, have hard ridges instead of teeth or fangs that they use to eat their food. 

  • Example: Squirrel Tree Frogs 

6. No Teeth At All: 

Many species lack any kind of dentition and rely solely on their tongues for capturing prey. 

  • Example: American Bullfrogs

Why do some frogs have teeth?

  • Using Teeth for Grip:

The presence of teeth or fangs can allow frogs to grip their prey more securely and tear it apart more easily.

  • Eating Harder Prey:

Having teeth may also be advantageous when preying on harder-bodied invertebrates such as beetles, crustaceans, or mollusks which require more force to break down and consume.

  • Increased Hunting Efficiency:

Frogs with larger dentition may be able to capture prey faster than those without teeth due to their bites’ increased biting power and accuracy.

  • Adaptation over Time:

Over time, some species have evolved specialized dentition to catch certain prey more effectively. This is an example of natural selection at work!

The difference Between Mammal Teeth & Frog Teeth

1. Number of Teeth:

Mammals typically have more teeth than frogs, which only possess a few maxillary and vomerine teeth (or no dentition).

2. Shape & Structure:

Mammal teeth are usually flat and rounded, while frog teeth tend to be sharp and pointed. The shape of frog teeth is adapted for gripping prey securely.

3. Function: 

Mammal teeth primarily serve for chewing and grinding food, whereas frog teeth are used mainly for catching prey or holding it in place as it’s eaten.

4. Orthodontics Not Necessary!: 

Frogs do not require orthodontic treatments! Since they don’t use their teeth for chewing, they never need to worry about cavities or other dental issues. If you are interested to know another animal, like snakes who chew their food then visit this page.

5. Replacement: 

While mammal teeth are permanent, frogs can replace their teeth multiple times throughout their lifetime.

In conclusion, frogs may have some form of dentition depending on the species, but it is typically much less developed than mammals. Frogs use their teeth and tongues for hunting prey, while mammals use theirs for grinding and chewing food. Additionally, mammalian teeth cannot be replaced like those found in some frog species can! Ultimately, observing the differences between these two types of animals regarding tooth structure and function is fascinating.

Frog Teeth Evolution

  • Early Frogs: Ancient members of the frog family, like Prosalirus, had teeth and could eat small invertebrates.
  • Reduced Dentition: Over time, certain species lost their dentition or developed only rudimentary maxillary and vomerine teeth for gripping prey.
  • Adaptive Advantage: This adaptation allowed them to catch larger prey items more efficiently than before without relying on biting power alone.
  • Tongue Prey Capture: Some frogs today have evolved specialized tongues adapted for catching and consuming prey more easily than traditional dentition allows.
  • Specialized Teeth: Species like the red-eyed tree frog have adapted hard ridges instead of teeth to catch prey more effectively.

In conclusion, evolution has caused some species of frogs to lose their dentition completely or develop specialized dentition better suited for catching prey. This adaptation allows them to hunt and consume various food items more efficiently!

Therefore, it is essential to understand the differences between different types of frog teeth to appreciate the unique characteristics and specializations found within this diverse family.

Tooth Loss In Frog: The Impact On Frogs’ Diets

  • Without any form of dentition, frogs cannot take advantage of certain nutritious foods, such as seeds or nuts, which require chewing or grinding.
  • Those without dentition may rely solely on soft-bodied prey such as insects, worms, and other small invertebrates to survive.
  • Some species have adapted specialized tongues to assist with consuming food items that require more effort than can be provided by rudimentary dentition or none.


How Many Teeth Do Frogs Have?

The number of teeth varies by species. Some frogs have no dentition, while others possess maxillary and vomerine teeth for gripping prey.

Do Frogs Chew Their Food?

Frogs often swallow their food whole or use specialized tongues to capture prey instead of using their teeth to grind or chew it.

Which Frog Has Teeth?

Some species of frogs, such as the red-eyed tree frog, possess specialized ridges instead of true teeth for gripping prey.

Does A Frog Need Teeth, And Why?

Frogs do not need teeth to survive as they swallow their food whole or capture prey with tongues. Teeth are primarily used for grinding and chewing food, which is unnecessary for most frog species.

What Frog Has Sharp Teeth?

Some species of frogs, such as the fire-bellied toad, have sharp teeth for gripping prey.

Can Frog Teeth Regrow?

Yes, some species of frogs can regrow their dentition multiple times throughout their lifetime, depending on the species.


Frogs have a variety of dentitions depending on the species. Early frogs possessed teeth and could eat small invertebrates, while some modern species have evolved specialized tongues or non-traditional ridges instead of true teeth for consuming prey.
