We all dread the day we’ll see that something is wrong with our pets’ health – and mouth rot is an issue that is usually quite traumatic to witness
All animals can get sick, including the captive ones. Although leopard geckos are particularly hardy pets, they still can suffer from an illness – especially if they live in inadequate conditions.
Mouth rot is one condition that is commonly connected with bad keeping conditions, but it is not all that is
As a loving and responsible leopard gecko owner, at this point, you’re probably wondering:
- Why does mouth rot happen?
- How do you cure mouth rot in leos?
- How to prevent mouth rot?
If you want to know the answers to these questions – this article is all about mouth rot. We’ll cover why it occurs, How to prevent it, and how best to treat it if it happens.
The topic is certainly not pretty, but fear not – the solutions are out there, and I intend to lay them out for you.
What Is Mouth Rot?
Mouth rot, also known by its less graphic medical name infectious stomatitis, is a bacterial infection of the mouth. It can happen to lizards, snakes, and turtles – and leopard geckos are unfortunately not an exception. It is one of the most common leopard gecko mouth problems (if not the most common).
The infection starts when bacteria invade the reptile’s mouth tissue. It is important to note that mouth rot is not caused by some specific pathogen but rather by the overgrowth of bacteria that commonly live in the mouth.
That means that mouth rot occurs when something is wrong with your leo’s immune system, the environment, or both.
How Do I Know If My Leopard Gecko Has Mouth Rot?
In leopard geckos, the symptoms of mouth rot are the same as in other reptiles.
They can include:
- Loss of appetite (the mouth are inflamed, and eating becomes too painful)
- Redness of the lining of the mouth
- Visible puss or dead tissue in the mouth
- Open abscess
- Liquids oozing from the mouth and the nose.
If mouth rot is not treated, it can spread to the rest of the digestive tract (hence the medical name stomatitis) and lungs, causing pneumonia.
The common symptoms of pneumonia in leopard geckos are:
- Mucus or mucus bubbles around the nostrils
- Difficulty breathing
Why Does Mouth Rot Happen?
As with most unspecific bacterial infections, many circumstances can contribute to the development of mouth rot in leopard geckos.
Since mouth rot is caused by bacteria commonly found in the reptile’s mouth, it is an immune dysfunction that enables the infection to occur.
When the immune system is down (which can happen for several reasons, as I’ll discuss below), it can’t keep the number of these germs under control. Overgrown bacteria take their opportunity and start feeding on the reptile’s tissues, causing damage.
The bacteria cause inflammation, and in severe cases, the tissue goes necrotic (hence the term ‘rot’).
So, how can your leo’s immune system become compromised?
In the case of mouth rot, the most common reason is inappropriate (too high) humidity and inadequate temperature.
Also, poor diet, lack of supplementation, and injuries of the mouth can bring on the disease as well.
However, even if you’re doing everything perfectly, an underlying health issue or simply old age can serve as a base for the development of mouth rot.
Feeding Tips to Avoid Mouth Rot
Larger feeder insects such as super worms will try to defend themselves when your leo grabs them. They have strong mandibles (insect jaws) and can bite your gecko. If they grab the mouth tissue – there’s an opportunity for mouth rot development.
That is the reason I crush the head of each superworm with feeding tweezers before offering it to my leo. It is a bit gruesome, but they would get crushed seconds later in the gecko’s mouth anyway – and safe is safe, right?
While I’m at it, the choice of tweezers is crucial to avoid any injuries during feeding if you use them. Always use tweezers specially designed for reptile feeding. Alternatively, you can repurpose plastic toy tweezers (e.g., from toy medical sets), but make sure they have absolutely smooth edges and tips.
How Do You Treat Mouth Rot in Leopard Geckos?
If your leopard gecko is showing the symptoms of mouth rot, the best course of action is is to take him to a specialized reptile vet as soon as possible.
A typical mouth rot treatment usually includes a course of antibiotics and local antiseptic cleaning of the infected area and the entire mouth.
In severe cases, surgery may be required to remove any dead, necrotic tissue.
Leo’s mouth will need some time to heal. In difficult cases, they won’t be able to use their mouth for a while. That means they will also require nutritional support and fluids provided by the vet.
How Do You Prevent Mouth Rot in Leopard Geckos?
Prevention is always better than the cure – and preventing mouth rot is relatively easy if you follow the best leopard gecko keeping practices.
Ensure that the temperature and humidity are always suitable for the species.
Leos do not live in humid areas, so it is essential to ensure that the humidity level doesn’t rise (between 30 and 40% is ideal) and that air circulation is fair.
To Sum It Up
Mouth rot is a common problem in all pet reptiles. However, it cannot occur out of the blue.
Favorable circumstances for mouth rot development include inadequate husbandry, mouth injury, underlying health conditions – or any combination of these factors that will result in immune deficiency.
The best way to prevent mouth rot is to keep your pet leo in the right conditions, with a particular focus on proper nutrition, temperature, and humidity. Ensuring good hygiene is also a must. If an infection does occur, the critical thing is to take your gecko to the reptile vet.
I hope you have enjoyed the article and that now you feel empowered to deal with mouth rot in reptile pets. As you can see, just being a responsible leo owner goes a long way in preventing the conditions?
