The causes for mouth rot in geckos include:

  • Stress. The main cause for Crested gecko mouth rot is stress. If your gecko is stressed, their immune system won’t function properly and they will be more susceptible to different bacteria, viruses or fungi
  • Incorrect temperature and humidity levels
  • Parasites
  • Trauma/injury. If your Crested gecko constantly rubs its nose or head on the tank walls, it can result in sores that allow for bacteria, viruses, and fungi such as such as Pseudomonas, Aeromonas, Salmonella, Klebsiella, and Mycobacterium to enter and cause infection
  • Incorrect diet. Poor nutrition such as Vitamin C deficiency or incorrect Calcium/Phosphorous levels can result in mouth rot
  • Chewing on substrate/bedding such as coconut fiber

The causes mentioned above such as incorrect habitat setup, wrong temperature/humidity can cause stress to your gecko and weaken their immune system. If your gecko’s immune system is not fully working, it can result in an infection such as mouth rot.

As mentioned earlier stress can weaken your gecko’s immune system and result in an infection such as mouth rot.

It’s essential that you can recognize the symptoms of mouth rot, so you can catch the diseases early and act quickly to help your gecko recover.

Most often Crested gecko mouth rot begins with excessive salivation. Then, oral cavity tissues might develop little pinpoint haemorrhages that look like red dots. They are also known as “petechiae”.

Other symptoms of Crested gecko mouth rot include:

  • Loss of appetite
  • Not drinking
  • Cuts in the mouth
  • Food stuck in teeth
  • Puss or dead tissue around mouth
  • Drainage from mouth and nose
  • Increased amounts of mucus in the oral cavity
  • Excessive salivation
  • Swelling or reddening around or in the mouth
  • Inability to close the mouth
  • Reduced or absent tongue flicking
  • The lining of the mouth can become eroded. This will result in developing “cottage cheese” appearance which is either yellow or white-gray in color

In severe cases, symptoms might include:

  • The head might be swollen
  • Infection can spread to the jaw and/or cranium (skull)
  • Teeth can become loose
  • Pneumonia might develop
  • Bleeding. If the tissue becomes cracked, it might bleed whenever the gecko opens their mouth

If you notice any of the mentioned symptoms, you should take your Crested gecko to the vet to be properly diagnosed and treated.

Crested Gecko Mouth Rot – Diagnosing It

It’s really important to properly diagnose diseases such as Crested gecko mouth rot. If not diagnosed on time or left untreated, the surface tissue can die and spread to deeper tissues, including the bone.

If you suspect that your Crested gecko is suffering from mouth rot, you should take them to the vet who will diagnose them by doing the following:

  • History. The first thing your vet will ask you is about your Crested gecko’s living conditions such as temperature/humidity levels, diet and behaviors
  • Physical exam to confirm the mouth rot

Further tests might include (but not in all cases):

  • X-ray of the head and the body can determine if the bones and organs are affected
  • Blood and plasma tests can establish any anomalies
  • Bacterial culture and sensitivity tests help identify if there is any bacteria present
  • Fungal isolation test can establish if any fungi is present in the tissue
  • Cytology can establish if any of the cells are inflamed
  • Biopsy. In some cases, tumors can develop in the tissues around the mouth. In that case, the vet needs to do a biopsy of the affected tissue in order to come up with a diagnosis

Crested Gecko Mouth Rot – Treatment

If mouth rot is caught early on, your vet will prescribe treatments such as:

  • Cleaning the mouth. The vet will clean the gecko’s mouth with a gel and show you how to continue the treatment at home. It’s important to not overuse the gel to avoid further damage of the tissue
  • Antibiotics or antifungal agents. The vet will show you how to properly administer the meds
  • Oral antiseptic
  • Calcium. If the vet establishes that poor nutrition is the cause for the mouth rot, they will prescribe additional vitamins and minerals. The additional calcium should help your gecko’s jaw bones become stronger and avoid teeth decay
  • Surgery. In some severe cases, surgery might be required to remove dead or damaged tissue

It’s important to remember that Crested gecko mouth rot is a serious condition and if left untreated, it can result in death.
