Iguanas, with their striking appearance and intriguing behaviors, are popular reptiles both in the wild and as pets. These fascinating creatures belong to the Iguanidae family and are primarily found in Central and South America, as well as the Caribbean. One common question that arises among those who encounter iguanas is: do iguanas have teeth? Understanding the dental structure of iguanas is essential for comprehending their feeding habits, dietary needs, and overall behavior. In this article, we will explore the anatomy of iguanas, focusing on their teeth, their role in an iguana‘s diet, and how these reptiles use their teeth in the wild and in captivity. By examining the different types of teeth and their functions, we aim to provide a comprehensive overview of iguana dentition and its significance to their survival and well-being.
Iguanas Have Teeth
All species of iguanas have sharp pleurodont teeth. These teeth are fused or ankylosed to the jaw and are specialized for tearing apart plant matter and insects. Pleurodont teeth are attached to the inner sides of the jawbone, a feature common among many reptiles. These teeth are not rooted deeply like the teeth of mammals, but they are still quite effective.
Iguanas have a unique dental structure. Their teeth are designed to handle their specific diet, which primarily consists of leaves, fruits, and flowers. This dental adaptation allows them to efficiently process tough plant material, making them well-suited for their herbivorous lifestyle.
Tooth Structure
Iguanas typically have between 80 to 120 individual teeth at any given time. Their teeth resemble tiny, serrated, diamond-shaped blades attached in neat, uniform rows. Unlike humans, all their teeth are identical in size and shape. This uniformity is beneficial for their diet, as it ensures that every tooth can effectively tear and shred plant material.
The teeth are continuously replaced throughout the iguana’s life. As an iguana wears down its teeth from constant use, new teeth grow in to replace the old ones. This process, known as polyphyodonty, ensures that iguanas always have functional teeth for feeding.
Iguana teeth are also quite sharp. Despite their small size, these teeth can cause significant damage if an iguana feels threatened and decides to bite. The sharp edges and serrated structure make them effective not only for feeding but also for defense when necessary.
Function
Iguanas primarily use their teeth for eating and tearing. They don’t chew food; instead, they break it down into smaller pieces before swallowing. The sharp, serrated edges of their teeth allow them to slice through tough plant material with ease. Once the food is in small enough pieces, the iguana swallows it whole.
Their digestive system is adapted to handle large pieces of plant material. Iguanas have a long, complex digestive tract that helps break down fibrous plant matter. The teeth play a crucial role in the initial processing of food, making it easier for the digestive system to do its job.
In addition to eating, iguanas may use their teeth for other purposes. During social interactions, especially among males, biting can be a way to establish dominance. In these situations, the teeth can cause injuries, which serve as a deterrent to challengers.

Baby Iguanas
Baby iguanas are born with fully-formed teeth, which help them break out of their shells and start feeding immediately. These teeth are essential for their survival, as they allow the young iguanas to begin eating as soon as they hatch. The ability to feed right away is crucial for their growth and development.
The teeth of baby iguanas are similar in structure to those of adults, though they are smaller. As the iguana grows, so do its teeth. The process of tooth replacement continues throughout the iguana’s life, ensuring that it always has the necessary tools for feeding.
The presence of teeth at birth also helps baby iguanas defend themselves. While they are vulnerable and small, their sharp teeth can still inflict damage on potential predators. This early development of teeth is a vital part of their survival strategy.
Self-Defense
While iguanas mainly use their teeth for eating, they may also use them for self-defense when necessary. An iguana’s primary means of defense include using its tail to whip at threats, fleeing to safety, and biting if cornered. When an iguana bites, it can deliver a painful and potentially damaging bite due to the sharpness of its teeth.
In the wild, an iguana’s teeth can deter predators. A well-aimed bite can cause enough pain and injury to make a predator think twice about attacking. In captivity, iguanas may bite if they feel threatened or stressed. Handling iguanas properly and understanding their behavior can help prevent such incidents.
In addition to defense, iguanas may use their teeth in social interactions. Dominance disputes among males can involve biting, along with other aggressive behaviors. These interactions help establish social hierarchies within iguana populations.
Conclusion
In conclusion, iguanas do have teeth, and these teeth are highly specialized to meet their dietary and survival needs. Their sharp pleurodont teeth are an essential part of their biology, allowing them to effectively process tough plant material and defend themselves when necessary. Understanding the structure and function of iguana teeth can provide valuable insights into their behavior and ecology.
Iguanas have between 80 to 120 individual teeth at any given time, and these teeth are continuously replaced throughout their lives. Their teeth are identical in size and shape, designed to efficiently tear and shred plant material. Baby iguanas are born with fully-formed teeth, which are crucial for their immediate feeding and defense.
While iguanas primarily use their teeth for feeding, they can also use them for self-defense. Their sharp teeth can deliver painful bites, deterring predators and helping establish social hierarchies. Proper handling and understanding of iguana behavior can help prevent bites in captivity.
Overall, iguana teeth are a fascinating example of how reptiles have adapted to their environments and diets. The specialized structure and function of these teeth highlight the incredible diversity and complexity of reptile biology. Whether in the wild or in captivity, iguanas rely on their teeth for survival, making them an essential aspect of their anatomy and behavior.
FAQs
1. Can an iguana bite you?
While the average iguana is harmless to humans, they have sharp teeth that can cause significant damage. The teeth of green iguanas are serrated and can cause deep bite wounds. Iguana teeth may look intimidating at first, but iguanas rarely bite unless they are provoked.
2. Is an iguana a good pet?
One of the most popular pet lizards is the iguana. However, they require a significant time investment and a high level of care. They have severe feeding and housing requirements and can grow to be fairly large and are extremely powerful. They can also be tough to tame and may grow hostile if not handled regularly.
3. Is iguana poisonous?
Iguanas possess atrophied venom glands that produce a weak harmless venom, and they are common pets to reptile collectors. Nevertheless, iguanas possess dozens of sharp serrated teeth. Although bites are relatively uncommon, they can produce serious injuries to faces, fingers, wrists, and ankles.
4. Do black iguanas bite?
Black spiny-tailed iguanas are excellent climbers, and prefer a rocky habitat with plenty of crevices to hide in, rocks to bask on, and nearby trees to climb. They are diurnal and fast moving, employing their speed to escape predators but will lash with their tails and bite if cornered.
5. Is it bad to touch iguanas?
We would advise against touching iguanas unless it’s absolutely necessary. However, if for some reason you do touch a wild iguana, wash your hands thoroughly right away. Iguanas may carry salmonella.
