Crested Gecko Dental Disease: Teeth and Gum Problems in Crested Geckos
- Crested gecko dental disease usually refers to inflammation or infection of the gums and mouth tissues, often called stomatitis or mouth rot in reptiles.
- Common warning signs include reduced appetite, trouble grabbing food, swelling or redness along the gumline, thick saliva or mucus, and weight loss.
- Poor husbandry, chronic stress, mouth trauma, retained shed around the face, and underlying illness can all make oral infection more likely.
- Early veterinary care matters because severe cases can spread into the jaw bones or lead to secondary respiratory or digestive problems.
- Typical U.S. veterinary cost range is about $120-$350 for an exam and basic treatment, $300-$800 with diagnostics and medications, and $800-$1,800+ for advanced imaging, anesthesia, debridement, or hospitalization.
What Is Crested Gecko Dental Disease?
Crested gecko dental disease is a broad term for problems affecting the teeth, gums, and other tissues inside the mouth. In reptiles, this is often described as stomatitis or infectious stomatitis. The condition can start with mild gum irritation and redness, then progress to swelling, discharge, tissue damage, and pain if it is not treated. (merckvetmanual.com)
In crested geckos, mouth problems may be easy to miss at first because these lizards often hide discomfort. A gecko may still look alert while eating less, dropping food, or losing weight slowly over time. As inflammation worsens, the tissues along the tooth rows can become visibly abnormal, and severe infection may extend deeper into the jaw. (merckvetmanual.com)
Dental disease in a crested gecko is rarely only about the teeth themselves. It is often a sign that something else needs attention too, such as enclosure humidity, temperature, sanitation, nutrition, trauma, or another illness that has weakened the immune system. That is why your vet will usually look at the whole picture, not only the mouth.
Symptoms of Crested Gecko Dental Disease
- Eating less or refusing food
- Trouble grabbing, chewing, or swallowing food
- Weight loss or poor body condition
- Red, swollen, or irritated gums
- Thick saliva, mucus, or stringy discharge in the mouth
- Bad odor from the mouth
- Small red or purple spots, ulcers, or cheesy-looking debris in the mouth
- Dropping food, rubbing the face, or resisting handling around the head
- Visible jaw swelling or deformity
- Lethargy or signs of illness beyond the mouth
See your vet immediately if your crested gecko stops eating, is losing weight, has visible swelling, or has discharge, ulcers, or debris in the mouth. Mild redness can become a much bigger problem in reptiles because oral infection may spread into deeper tissues and even contribute to secondary respiratory or digestive disease. Early signs can be subtle, so any persistent change in appetite or mouth appearance is worth a prompt exam. (merckvetmanual.com)
What Causes Crested Gecko Dental Disease?
The most common cause of reptile stomatitis is bacterial infection involving organisms that are often already present in the mouth. These bacteria are more likely to cause disease when the mouth tissues are damaged or when the gecko's immune defenses are weakened. Tiny abrasions from prey items, enclosure furnishings, retained shed, or rubbing the face can all create an entry point. (merckvetmanual.com)
Husbandry problems are a major contributor. Reptiles depend on species-appropriate temperature, humidity, lighting, diet, and sanitation to keep their immune system and tissues healthy. For crested geckos, current care guidance places the enclosure around 72-75 F on the warm end, 68-75 F on the cool end, with 70-80% humidity and regular monitoring. When those basics drift off target, stress and illness become more likely. (petmd.com)
Nutrition can matter too. Reptiles need appropriate calcium, vitamin D, and overall dietary balance, and poor nutrition can contribute to weak tissues and other systemic disease. In some geckos, oral disease may also occur alongside metabolic bone disease, chronic dehydration, or other infections. Your vet may therefore treat the mouth problem and the underlying setup issue at the same time. (merckvetmanual.com)
How Is Crested Gecko Dental Disease Diagnosed?
Diagnosis starts with a careful history and physical exam. Your vet will usually ask about appetite, weight changes, diet, supplements, feeder insects, enclosure temperatures, humidity, lighting, cleaning routine, and any recent shed or trauma issues. In reptile medicine, husbandry details are part of the medical workup because environmental problems often drive disease. (merckvetmanual.com)
During the exam, your vet will look for gum inflammation, discharge, ulcers, loose or damaged teeth, jaw pain, and signs of dehydration or other illness. Some crested geckos need sedation or anesthesia for a complete oral exam, especially if the mouth is painful or if deeper structures need to be assessed. In exotic dentistry, a definitive diagnosis may require probing, charting, and imaging while the patient is anesthetized. (vet.cornell.edu)
Depending on severity, diagnostics may include skull or jaw radiographs to check for bone involvement, cytology or culture of abnormal material, and bloodwork if your vet is concerned about broader illness. These tests help separate mild surface inflammation from deeper infection, abscessation, or bone disease and guide which treatment option makes the most sense for your gecko. (merckvetmanual.com)

Questions to Ask Your Vet About Crested Gecko Dental Disease
Bring these questions to your vet appointment to get the most out of your visit.
- Does this look like mild stomatitis, deeper dental disease, or possible jaw involvement?
- What husbandry factors in my crested gecko's setup may be contributing to this problem?
- Should we do radiographs, cytology, culture, or other diagnostics now, or can we start with conservative care?
- Is my gecko painful, and what signs of pain should I watch for at home?
- How should I adjust feeding if my gecko is eating less or dropping food?
- What temperature and humidity targets do you want me to maintain during recovery?
- How will I know if the mouth is healing versus getting worse?
- What is the expected cost range for the treatment options you think fit my gecko's case?
How to Prevent Crested Gecko Dental Disease
Prevention starts with husbandry. Crested geckos do best when their enclosure stays within an appropriate temperature gradient and humidity range, with clean water, regular sanitation, and good ventilation. Current care guidance commonly recommends a warm side around 72-75 F, a cool side around 68-75 F, and humidity around 70-80% for this species. Use reliable thermometers and a hygrometer so you are measuring, not guessing. (petmd.com)
Diet matters too. Feed a balanced crested gecko diet and review supplements and feeder choices with your vet, especially if your gecko is growing, breeding, or has had prior health issues. Reptile nutrition and calcium balance affect tissue health and overall resilience, even when the first visible problem shows up in the mouth. (merckvetmanual.com)
Check your gecko regularly for subtle changes. Watch for reduced appetite, food dropping, weight loss, face rubbing, or any redness or debris around the mouth. Avoid enclosure hazards that can injure the face, and do not delay an exam if something looks off. Early treatment is usually easier, less invasive, and less costly than waiting until infection spreads. (merckvetmanual.com)
