Yes, a leopard gecko has a complete set of 100 fully-formed tiny conical teeth at birth. The reptiles are polyphyodonts, meaning they continually replace their old teeth with a new set every 3-4 months. Although leopard geckos are naturally docile, they can bite when hungry, threatened, or over-handled.

 Read on to learn more about leopard gecko teeth and be a pro leopard gecko pet owner or caregiver. Some of the pain points we’ll tackle include the following:

What’s the Appearance of Leopard Gecko Teeth?

These reptiles have minuscule, sharp-pointed, and conical-shaped teeth with sides converging incisively on both jaws. Further, the upper jaw typically has more teeth than the upper one.

Regarding composition, leopard gecko teeth resemble mammals- a thin outer protective enamel covering the dentin.

The tooth dentin makes up most of the tooth structure and consists of a yellowish tissue harder than bone but softer than enamel. Lastly, the cementum anchors the teeth roots to the jawbone.

Nevertheless, Leo teeth aren’t specialized or properly aligned like those of most mammals and other reptiles. Instead, the geckos have a near-uniform type and size of teeth lining their jaws from front to back.

Functions of Leopard Gecko Teeth

Why would a tiny creature like a leopard gecko need so many teeth? Out in the wild, Leos hunt down their prey, mostly insects and other little critters. Mostly, the reptiles rely on their agility to catch the prey and the teeth to clamp it down and swallow it.

Leos are unlike other animals that bite and chew their food before swallowing it whole. Instead, leopard geckos use their sticky tongue to catch their prey and use their teeth to hold down the prey and prevent it from squirming away as they swallow it.

Then, the flexible tongue and muscle movements inside the mouth push the food down toward the stomach.

The number, uniformity, sharpness, and orientation of teeth in a leopard gecko’s mouth guarantee the lizard a better grip as the Leo moves the prey into and down its mouth.

Further, Leos repeatedly strike their food on the ground or shake their heads vigorously if it’s exceedingly large to tear it into smaller pieces. Sadly, your pet Leo can lose teeth this way, so it’s best to feed the pet smaller insects at a time.

Do Leopard Geckos Bite?

Understanding all behaviors of leopard geckos is a solid first step in preparing for most eventualities that can affect your health or that of your pet. For instance, you’ll want to ascertain that Leos won’t be a danger to you or your children.

So, does the presence of teeth in a Leo’s mouth mean that the lizard bites too? Leopard geckos are typically docile, so they’re unlikely to bite their owner or handler. Instead, they prefer fleeing to fighting.

Nevertheless, Leos won’t hesitate to use their teeth to bite as a defense when provoked, especially when hungry, attacked, over-stressed, or when you try handling them against their will. Here are a few reasons a leopard gecko can bite:

• Hunger
• Leopard geckos are extremely territorial
• Provocation or Fear
• Anxiety or Stress buildup

1. Hunger

Hunger can make anyone moody, including most animals like leopard geckos. However, hunger can lead a leopard gecko to bite its owner or handler in two ways:

• If you try to handle a hungry Leo, it might mistake your fingers for food, thus bite you
• A hungry leopard gecko is usually aggressive and often bites anyone who tries to handle them

Trying to pick up or handle a hungry Leo is a bad idea. So instead, it’s best to feed your little reptile buddy before attempting to pet them.

2. Leopard Geckos are Extremely Territorial

Like most reptiles, leopard geckos are exceptionally territorial, especially males. They’ll aggressively fight to dominate that enclosure’s space, food, mates, and other resources. Thus, housing two or more male Leos in the same tank is touting violent aggression.

Likewise, handling a male leopard gecko before washing your hands after handling another male gecko can cause the Leo to bite. The male will usually mistake the scent on your hand for another male gecko, prompting its territorial aggression to kick in.

3. Provocation or Fear

Fear causes an animal’s defensive instincts to kick in. While most small creatures such as Leos and bearded dragons prefer fleeing to fighting, they’ll often face off the other creature when pushed to the wall.

Since leopard geckos are naturally docile, they often resort to other ways to warn you to keep off, such as tail-wagging, pointing the tail upwards, hissing, or screaming. Nevertheless, if you ignore the previous warnings, the lizard might fight back by biting.

Provoking a leopard gecko often causes it to be aggressive or afraid, prompting it to bite. Likewise, over-handling your Leo or trying to pet it against its will can provoke or cause it to be frightened, thus biting you. Therefore, it’s best to handle your pet Leo only when it’s in the mood for handling.

4. Anxiety or Stress Buildup

Unsuitable tank conditions such as unclean surroundings, inappropriate lighting, and unfavorable temperature and humidity levels cause anxiety and discomfort in leopard gecko pets.

As a result, the pet experiences stress buildup or other health complications like tail loss.

Similarly, adopting a new Leo or transferring one to a new enclosure often causes relocation stress.

Consequently, the lizard becomes restless and might respond aggressively to handling by biting. Thus, it’s best to avoid handling your Leo when they’re stressed or anxious to prevent bites.

Are Leopard Gecko Bites Painful?

We’ve established that leopard geckos can bite when pushed the wall. However, since they have such an astounding number of teeth, their owners often wonder whether the lizards’ bites hurt.

Fortunately, leopard gecko bites don’t hurt humans. Instead, it feels like a hard pinch than a bite. Moreover, they only leave a scratch instead of a wound. Here’s why:

• Leopard gecko teeth are too small to puncture the skin in most instances
• Leo jaws are too weak to inflict substantial damage on the human skin

Nevertheless, you might feel pain when bitten by a giant leopard gecko.

Are Leopard Geckos Venomous?

Luckily, leopard geckos are non-venomous, so their bites are also non-venomous. Nonetheless, the geckos’ bites are sometimes infectious due to bacteria such as Salmonella or other disease-causing microorganisms in their mouth.

Leopard gecko bites are largely harmless since they’re usually shallow and painless. However, an open wound from a Leo’s bite can develop infections and deteriorate. Therefore, it’s best to seek medical attention if a leopard gecko’s bit draws blood.

Alternatively, treat the bite like any other flesh wound or a minor cut to prevent infection. Wash your hands carefully with soap water and then clean the wound with disinfectant, antibacterial soap, Sodium Peroxide, or alcohol before covering it with a standard plaster.

What Should You Do When a Leopard Gecko Bites You?

Most people react instinctively to a leopard gecko bite by whisking the hand away in panic. Unfortunately, in most instances, abruptly snatching the hand away whisks the pet violently into the air and can result in severe injuries, concussions, or death.

Additionally, fiercely pulling a leopard gecko off your skin causes it to hold more firmly. As a result, the Leo’s teeth might leave you with open cuts that can be painful and infectious. Thus, it’s best to stay relaxed and let the gecko remove the teeth from your skin. Alternatively, gently nudge the Leo away from your skin.

How to Prevent Pet Leopard Geckos from Biting?

Leopard geckos are naturally peaceful and won’t bite unless they’re agitated (from provocation), scared, hungry, or stressed out. Thus, the best way to avoid Leo bites is by keeping off anything that prompts the lizard to bite.

Here’s what you can do to stay on the safe side of a leopard gecko’s teeth:

• Avoid handling an anxious or stressed-out Leo. Some obvious warning signs to keep off your pet Leo include hissing, wagging the tail, and screaming. Besides getting a bite, ignoring these warning gestures can easily break the bond between you and your Leo.
• Feed your pet a healthy, balanced, and sufficient diet to maintain good health. Remember, trying to handle a hungry leopard gecko can result in bites
• House only one male Leo per enclosure to avoid aggression, nasty fights for dominance, and potential casualties, as male leopard geckos are extremely territorial
• Allow your pet leopard gecko sufficient time to adjust to its new habitat before trying to handle them. Adopting a new Leo or moving it to a new tank often leads to relocation stress. We’ve already established that handling a stressed-out gecko is touting a bite
• Maintain your leopard gecko’s tank in pristine condition by providing appropriate lighting and heating, maintaining hygiene, and providing a suitable substrate to keep the pet healthy and comfy. As a result, the Leo is less likely to bite you
• Always wash your hands thoroughly when handling different leopard geckos. Male Leos can mistake the smell on your hands for another male leopard gecko’s scent, prompting it to bite you
• Sudden movements around a leopard gecko can scare the lizard into believing a predator attack is imminent, leading it to bite you. Therefore, approaching your gecko slowly and carefully is best to ensure the lizard can see you.

Do Leopard Gecko Teeth Regrow After Falling Out?

Since a leopard gecko’s teeth are vital to its survival (feeding and defense), you must wonder whether the teeth regrow after falling out.

Yes, new leopard gecko teeth replace the old ones. However, tooth regrowth occurs differently in Leos and other reptiles than in humans and other mammals.

Leopard geckos, reptiles, amphibians, and toothed fishes are polyphyodonts- they continually replace their teeth throughout their lives. Moreover, unlike diphyodont creatures (typically mammals) with only two sets of teeth their entire life, polyphyodont animals are never toothless as their tooth replacement is continuous.

And there’s more.

Leopard geckos and most lizard species have pleurodont teeth- teeth anchored to their inside jaws via strong roots. Since the teeth aren’t fused to the jawbone, their weak attachment allows new teeth to sprout in the same place as the old ones.

How Does Tooth Replacement Happen in Leopard Geckos?

When a baby Leo hatches, it has a set of 100 fully-formed teeth. As the gecko ages, new teeth continually grow beneath the jaw under the old ones and regrow immediately the Leo loses a tooth. Moreover, a new set of teeth replaces the old teeth every 3-4 months.

Tooth replacement in Leos occurs continuously via a process coined ‘Marching Molars.’ It begins at the back of the Leo’s jaw, where the new teeth gradually nudge the old teeth forward until the front teeth fall out. Fortunately, the old teeth don’t risk being swallowed as they fall from the back toward the front.

Do Leos Require Special Oral or Dental Care to Safeguard Their Teeth?

Leopard gecko teeth always fall out, either naturally or as a result of biting on a hard object. Fortunately, new teeth promptly replace lost or old teeth. Still, ensure you feed your gecko the right type and size of food to protect its teeth from ripping out before their time.

The biggest worry in the oral health of a leopard gecko comes from bacterial infections such as mouth rot. Here’s a little about the disorder:

Mouth Rot

Mouth rot is a potentially fatal condition that manifests as the abnormal proliferation of bacteria inside the mouth due to infected lesions or trapped food. It’s caused by:

• Unsuitable Diet
• Unhygienic leopard gecko tank and living conditions.

Unsuitable Diet

Poor nutrition is a major cause of mouth rot in leopard geckos. Feeding your pet Leo a diet deficient in vital food elements such as vitamins, calcium, phosphorus, and other essential nutrients endangers its overall health and cause unwanted health complications such as mouth rot.

Equally, giving your Leo unhealthy foods can cause mouth rot. For instance, the sugars in processed and canned foods can cause gum or teeth diseases. Worse yet, they can pave the way for mouth rot.

Moreover, giving a leopard gecko unsuitably hard foods can also lead to mouth rot. The lizard might lose some teeth after biting on extremely hard prey or develop traumatic lesions, which can worsen into mouth rot.

Furthermore, continually feeding your Leo a wrong food choice can cause it to refuse to eat. Consequently, the pet might get malnourished and suffer other potentially fatal ailments like Metabolic Bone Disease.

Fortunately, feeding your pet Leo a balanced diet in the right proportions at the recommended frequency is often sufficient to guarantee the pet a healthy life.

Nonetheless, ensure you supply the pet with enough nutrient supplementation by gut loading or dusting the live feeder insects to promote a healthy life.

An Unhygienic Enclosure

Dirt accumulation and unhygienic living conditions are among leopard geckos’ leading causes of mouth rot. Since bacteria thrive in dirt, a dirty tank can easily lead to bacterial overgrowth in a Leo’s mouth, causing the dreaded mouth rot.

Additionally, unsuitable living conditions, particularly poor lighting and heating setups and durations, negatively impact a leopard gecko’s nutrition and lead to multiple severe health complications, including mouth rot.

Signs of Dental and Oral Complications in Leopard Geckos

Being observant and proactive in learning and addressing dental issues before they bloom into severe complications is crucial to pet leopard gecko care. Here are a few signs that your Leo’s dental or oral health is in turmoil:

• Visible Mouth Inflammation
• Loss of Appetite and Diminished Desire to Drink Water
• Foul Odor emanating from the mouth
• Drooling.

Visible Mouth Inflammation

Visible signs of inflammation in or around a leopard gecko’s mouth often indicate that the pet is suffering from mouth rot.

Inflammation in a Leo’s mouth can manifest in inflamed tissue around the teeth, swollen mouth, face, and other parts of the head, or yellow-colored puss with a foul odor around the reptile’s nose.

Loss of Appetite and Diminished Desire for Water

A leopard gecko suffering from dental or oral complications such as oral lesions usually experiences a reduced appetite for food and a decreased desire to uptake water due to its discomfort and pain.

Foul Odor in the Mouth

Bacterial imbalance, food remnants, and necrotic (dead) tissue inside a Leo’s mouth often result in an offsetting odor in the gecko’s mouth.

Drooling

Leopard geckos suffering from oral infections such as mouth rot often secrete excess saliva, which collects as drool around the mouth or slobbers down. Moreover, the Leo might keep its mouth open and let the drivel flow out.

Note: dental and oral infections such as mouth rot in leopard geckos can turn fatal if you ignore them or detect them early and treat them appropriately.

Pro Tips to Maintain Good Leopard Gecko Oral and Dental Health

Although you don’t need to brush your pet leopard gecko’s teeth, apply these tips to keep its oral health in pristine condition:

• Perform your pet’s daily or frequent oral examinations to identify dental and other oral problems early. To open your Leo’s mouth, gently stroke or tap its snout or gently massage the pet’s jaw’s underside.
• Stay vigilant by watching for any signs of mouth rot or other dental-related complications, and then address the issue promptly before the problem compounds. Remember, Leos are notorious for concealing weakness, which can lead to easy predation in the wild.
• Immediately but gently dislodge stuck food or substrate from the Leo’s mouth as it can rot or rub and injure the mouth, causing mouth rot or other oral problems. You can use a pair of tweezers or water squirt for the exercise
• Schedule regular professional reptile pet vet sessions for your pet Leo to prevent, treat, and control various dental and oral issues. Remember, a licensed herpetologist is best placed to handle sensitive leopard gecko oral complications such as mouth rot.

Final Verdict: Do Leopard Geckos Have Teeth?

Yes, leopard geckos have teeth. Baby Leos hatch with 100 fully-formed teeth, which regrow continually to replace the fallen or old teeth every 3-4 months.

Since Leos are naturally docile, they rarely bite unless you provoke them. However, a leopard gecko can bite if it’s hungry, stressed out, or if you handle it inappropriately (against its will or before thoroughly cleaning your hands after handling another gecko).

Fortunately, Leos aren’t venomous and are hardly painful but feel like a hard pinch. Nevertheless, if a Leo’s bite draws blood, it’s best to treat it carefully or seek medical attention to prevent infections.
