Mouth rot, also commonly known as infectious stomatitis or necrotic stomatitis, is a serious condition that affects certain reptiles. It leads to severe oral infections that can be very painful and end in serious health complications when not treated promptly. Understanding mouth rot is super important for reptile owners to ensure their pets’ health. 

 

In this article, we discuss which animals are most likely to catch this condition, along with its symptoms, treatments, and prevention methods. Let’s go!

Mouth rot can have a big effect on many reptiles. Unfortunately, this is a pretty common reptile illness, and many reptile owners may deal with this headache at one point or another. Some of the most common animals that deal with this infection are:

 

  • Snakes: Pet snakes that can develop mouth rot include corn snakes and ball pythons. 

 

  • Lizards: Species such as iguanas, bearded dragons, and geckos are at risk.

 

 

While these animals can have different symptoms of mouth rot, the underlying cause is generally the same: a bacterial or fungal infection. Keep a close watch on your pet to ensure they don’t suffer from this awful condition.

Animals dealing with mouth rot can show quite a large variety of symptoms. These symptoms generally vary depending on the severity of the infection, but some of the most common signs include:

 

  • Swelling and redness: Early signs of mouth rot can include inflammation of the gums and the tissues around the mouth. Some affected areas may be red and swollen.

 

  • Discharge: Affected reptiles can have a thick pus or discharge from their mouth, often with an unpleasant, foul smell.

 

  • Loss of appetite: Due to the pain and difficulty eating, reptiles that have mouth rot will often exhibit a loss of appetite or a complete refusal of any food.

 

  • Difficulty closing mouth: In the more advanced stages, reptiles can have a lot of trouble closing their mouths. This can result in drooling and even an inability to hold food.

 

  • Behavioral changes: Affected reptiles can become irritable, and lethargic, and exhibit many signs of distress.

Most commonly, mouth rot is caused by a large combination of factors, including: 

 

  • Bacterial infections: The most common culprits of mouth rot are bacteria such as Pseudomonas, Aeromonas, and Streptococcus. These awful bacteria can enter through wounds or abrasions in the mouth.

 

  • Fungal infections: In some cases, fungal infections are caused by Candida or Aspergillus and can contribute to mouth rot.

 

  • Poor husbandry: Sometimes, inadequate habitat conditions, such as improper temperatures, humidity, and sanitation, can negatively affect your reptile’s immune system. This makes it much more susceptible to infections.

 

  • Trauma or injury: Injuries to the jaw or mouth can make a reptile vulnerable to infection. 

 

  • Nutritional deficiencies: Poor diets can weaken a reptile’s immune system, making the animal much more prone to infections. A healthy and stable diet for your animal is critical to maintain their health. 

 

How Veterinarians Diagnose Mouth Rot

Diagnosing mouth rot in reptiles most often involves a super thorough examination by a qualified vet. This process will usually include:

 

  • Conducting a veterinary examination: Your vet will examine your pet’s mouth for signs of any swelling, redness, discharge, ulcers, or necrotic tissue. They’ll also check the overall health of your pet, including signs of dehydration or weight loss.

 

  • Taking a clinical history: Your vet will ask about your reptile’s health history, recent injuries, any changes in behavior, and what their habitat is like to find any potential contributing factors.

 

  • Running tests: Your vet will do oral swabs and cultures to identify bacteria or fungi, blood tests to assess overall health and find any systemic issues, and x-rays to know the extent of the infection.

 

  • Ruling out other illnesses: The vet will rule out any other oral conditions to ensure a correct diagnosis of mouth rot. 

 

  • Monitoring: Regular follow-up visits are super important to see if the treatment worked and whether your pet needs any additional care.

Effectively treating mouth rot means getting your pet prompt veterinary attention. A medical professional may recommend: 

 

  • Antibiotics and antifungals: Based on the results from your vet, they may prescribe oral or topical antibiotics and antifungal medications to get rid of the infection.

 

  • Debridement: In severe cases, surgical removal of necrotic tissue may be needed to help with healing. 

 

  • Supportive care: Nutritional supplements might be needed to support your pet’s recovery.

 

  • Habitat changes: Make sure that you regularly clean your reptile’s enclosure and ensure the correct temperature and humidity levels. 

 

Above all else, in the days following your veterinary visit, monitor your pet for any troubling signs, such as extreme fatigue or non-responsiveness.

Preventing mouth rot really isn’t hard. Firstly, it involves keeping a proper habitat for your pet. As noted, this involves ensuring the right humidity levels and temperature. It’s also important to clean any animal waste within a reasonable period, as this could lead to fungal and bacterial infections. 

 

Secondly, feed your reptiles a balanced diet to keep their immune system strong. A proper diet depends on your pet’s age, type, and weight. While some pet snakes do well with a weekly feeding, other reptiles need more consistent eating schedules. 

 

Finally, bring your animal to the vet on a regular basis to prevent any life-threatening conditions. If you’re concerned about cost, many pet insurance policies offer coverage for routine visits and appointments. While it may seem like a large investment at first, putting some money aside can prove useful if your reptile suffers a veterinary emergency.
