There are several reasons why your blue tongue skink might contract mouth rot. Luckily, all these reasons are human made errors that you can avoid. Ideally, mouth rot in blue tongue skinks and other reptiles come from low immune systems.

The immune system can occur due to:


When your blue tongue skink habitation does not match their natural habitats, they tend to get stressed quickly. It can be due to inadequate heating, too much or too little humidity, pest invasion, among other reasons.

Stress suppresses the immune system of blue tongue skinks and makes them susceptible to diseases and infection. When the immune system does not perform against foreign antigens, they can easily proliferate and multiply in epithelial and mucosal cells causing infections. So, it is necessary to remove the stress-inducing factors.

To keep your blue tongue skink healthy, you must ensure that you provide a suitable habitat.

You must include several things in your blue tongue skink’s cage to make their habitat comfortable and stress-free. These things include;

A Big Enclosure

Blue tongue skinks require a big enclosure that they can easily move around. To make your blue tongue skink feel comfortable enough in its cage, you must ensure that it is at least two times bigger than it is.

A Good Substrate 

The substrate or blue tongue skink’s bedding should be at least 4 inches deep to enable your blue tongue skink burrow in when they need to. It should also contain adequate humidity, depending on your blue tongue skink species.

You must also ensure that the substrate is free from parasites such as mites. And, you should replace the substrate regularly and thoroughly clean the cage with reptile friendly disinfectants. 

Basking Spot

Blue tongue skinks are highly likely to spend most of their day basking in the sun.  Thus, even in captivity, you must ensure that you include a basking spot for them to warm their body during the day. The best temperature to include in the basking spot for blue tongue skinks is 95-1050F.

Cool Spot

When blue tongue skinks bodies become excessively hot, they require cooling off their body in an area where the temperature is lower than the warm side. The cold spot should have a temperature ranging between 70-800F.
