Why Is My Crested Gecko’s Mouth Open? (7 Common Reasons)


Are you noticing your crested gecko with its mouth open and wondering what’s going on? Let’s explore the seven common reasons behind this behavior.

A crested gecko might have its mouth open due to thermoregulation, stress, respiratory infection, shedding, dental issues, dehydration, or just basking. Understanding these reasons can help ensure your gecko’s well-being.

Discovering the reasons behind your gecko’s behavior can provide valuable insights into its health and happiness. Let’s delve into each possibility to better care for your scaly friend.

Thermoregulation

Crested geckos, like many reptiles, regulate their body temperature by adjusting their environment. They might open their mouths to release excess heat when they feel too warm. This behavior helps them maintain a comfortable body temperature and avoid overheating.

To ensure your gecko’s comfort, provide a temperature gradient in its enclosure. This means offering warmer and cooler areas so your gecko can move between them as needed. Use a combination of heat lamps, heat mats, and ambient room temperature to create the ideal environment.

Additionally, monitor the temperature regularly with a thermometer to ensure it stays within the recommended range for crested geckos, typically between 72-80°F (22-26°C) during the day and slightly cooler at night.

Stress or Aggression

Stress or aggression can also cause a crested gecko to open its mouth. Factors such as loud noises, sudden movements, handling, or the presence of other pets can trigger stress responses in your gecko. Aggression may arise from territorial disputes or feeling threatened.

To minimize stress, create a calm and quiet environment for your gecko. Avoid sudden movements or loud noises near its enclosure, and handle it gently and infrequently. Provide plenty of hiding spots and visual barriers to help your gecko feel safe and secure.

If aggression is a concern, ensure that your gecko’s enclosure is appropriately sized and that it’s not overcrowded with other reptiles. If you have multiple geckos, observe their interactions closely and be prepared to separate them if necessary to prevent injuries.

Respiratory Infection

Respiratory infections are a common concern for crested geckos, especially if their enclosure’s humidity levels are too high. An infected gecko may display symptoms such as open-mouth breathing, wheezing, nasal discharge, or lethargy. If you notice these signs, it’s essential to seek veterinary care promptly.

To prevent respiratory infections, maintain proper humidity levels in your gecko’s enclosure. Use a hygrometer to monitor humidity levels regularly and adjust as needed. Aim for a humidity level of around 50-70%, with occasional spikes for shedding periods.

Provide good ventilation in the enclosure to prevent stagnant air, which can contribute to respiratory issues. Clean the enclosure regularly to remove any feces or food debris that could harbor bacteria and contribute to infection. Additionally, avoid using substrates that can become moldy or hold excess moisture, such as overly damp sphagnum moss.

Obstruction or Impaction

Obstruction or impaction can occur when a crested gecko ingests substrate, foreign objects, or large prey items that are difficult to digest. This can lead to blockages in the digestive tract, causing discomfort and potentially serious health issues.

To reduce the risk of obstruction, choose safe substrates such as paper towels, reptile carpet, or coconut fiber that are less likely to be ingested. Avoid loose substrates like sand or gravel, which can be accidentally consumed during feeding or exploration.

Offer appropriately sized prey items to your gecko to prevent choking hazards or digestive issues. If you suspect your gecko has ingested a foreign object or is experiencing symptoms of obstruction, such as loss of appetite, lethargy, or abdominal swelling, consult a veterinarian immediately.

Ensure your gecko has access to clean water at all times to stay hydrated, which can help prevent digestive problems. Regularly inspect the enclosure for any potential hazards or objects that your gecko could ingest accidentally. By taking these precautions, you can help keep your crested gecko happy and healthy.

Dehydration

Dehydration can lead to a crested gecko opening its mouth to breathe more effectively. Ensure your gecko has access to clean water at all times. Mist the enclosure regularly to maintain humidity levels, as crested geckos absorb water through their skin. Additionally, consider offering water in a shallow dish or using a dropper to provide hydration directly if necessary.

Watch out for signs of dehydration, such as sunken eyes, wrinkled skin, lethargy, or reduced appetite. If you suspect dehydration, consult a veterinarian promptly. In severe cases, your gecko may require fluid therapy to rehydrate properly.

Mouth or Dental Disease

Mouth or dental issues can also cause a crested gecko to keep its mouth open. Dental problems such as overgrown teeth or mouth infections can make it difficult for your gecko to close its mouth comfortably. Regularly inspect your gecko’s mouth for any abnormalities, such as swelling, redness, or discharge.

Provide your gecko with a varied diet that includes appropriate-sized insects and commercially available crested gecko diets. Avoid feeding foods that are too large or hard, as they can injure your gecko’s mouth. If you notice any signs of mouth or dental disease, seek veterinary attention promptly to prevent further complications.

Shedding

Shedding is a natural process for crested geckos, during which they shed their old skin to make way for new growth. As they shed, some geckos may open their mouths to facilitate the shedding process. This behavior helps loosen the old skin around their mouths and allows them to remove it more easily.

Ensure your gecko has proper humidity levels in its enclosure to support healthy shedding. Mist the enclosure regularly to maintain humidity levels between 60-80%. Providing a moist hideout, such as a small container filled with damp moss or paper towels, can also aid in shedding.

Observe your gecko closely during shedding to ensure it can remove the old skin properly. If you notice stuck shed around its mouth or toes, you can help by gently soaking the affected area in lukewarm water and carefully removing the old skin with a soft, damp cloth or cotton swab.

Avoid handling your gecko excessively during shedding, as this can cause stress and potentially interfere with the shedding process. Allow your gecko to shed in peace, providing a stress-free environment to ensure a successful shed and promote overall well-being.
