Do Leopard Geckos Have Teeth?

Leopard geckos have teeth. The teeth on leopard geckos are conical and neatly lined close to these reptiles’ upper and lower jaw. Leopard geckos’ teeth are pretty small and won’t cause damage to humans.

Why Do Leopard Geckos Bite?

Several reasons could make a leopard gekko bite its handler. Here’s a look at three main reasons why these reptiles bite:

Due to an injury

Just like humans, some leopard geckos could become aggressive after suffering an injury. Leopard geckos that just survived an attack due to an autotomy or flipping over may resort to biting.

Even if bites from leopard geckos have no significant impact, it’s the only defense they got left. If you notice your leopard gecko has an injury, try handling it without putting your fingers close to its mouth.

When frightened

Frightened leopard geckos could bite on anything close to them. Biting on stuff is a means of defense geckos will likely resort to whenever they feel cornered or intimidated. It is important for owners to make their leopard geckoes feel comfortable at all times.

Are Leopard Gecko Bites Dangerous to Humans?

Bites from leopard geckos do not pose a significant threat to humans, especially adults. But there’s a chance of bacterial infection from leopard geckos. Geckos that do not have access to complete care may become a host for bacteria. In most cases, domestic leopard geckos do not host bacteria due to the extensive care they receive.

If you have extra sensitive skin, it’s better to avoid handling geckos that haven’t received any treatment. The slightest bite from leopard geckos could result in injuries that may escalate.

What to Note if Your Leopard Gecko May Bite You

Reclusive Behavior

Whenever a leopard gecko exhibits some hermit traits, it may be an indication that it wants to bite something. Leopard geckos are more likely to become reclusive if they feel threatened. In some cases, a leopard gecko could hide itself if it’s injured or feeling ill.

Pooping on you

Leopard geckos rarely poop on their handlers, but if they do, it’s usually a precursor to biting. So, if a gecko poops on your hands or clothes, quickly put it back in its tank (don’t throw it).


A hissing leopard gecko may feel threatened by your presence and resort to biting. Whenever a gecko hisses constantly, get it in its tank and wait for a while before picking it up.

Hostile stance

A hostile leopard gecko usually sways its tail in an aggressive manner. Hostile geckos are more likely to bite on anything they get their teeth on.

Geckos do not have strong teeth that could cause their bites to have an impact. Since leopard gecko bites don’t hurt, owners have little to worry about when handling these reptiles.

Can leopard geckos carry disease?

Leopard geckos well catered for do not carry disease. But leopard geckos in an environment with poor hygiene could carry diseases other reptiles spread, most commonly salmonella.

Final Thoughts: Are Leopard Geckos Poisonous?

Are leopard geckos poisonous? No, they’re not, but could become disease carriers without proper care. It is important for owners to maintain their leopard geckos’ health to keep them safe from carrying diseases.

If you have soft skin and get bitten by leopard geckos, wash off the affected area and seek medical attention.

Generally, geckos are less likely to bite unless they feel threatened or need to eat. Leopard geckos are adorable creatures and may never bite their handlers at any time. Also, don’t expect a massive bite from leopard geckos as compared to other reptiles.
