Malocclusion (Dental Overgrowth)
🔎 Find by symptom
About this condition
In rabbits, guinea pigs, and related species, teeth grow continuously throughout life. If the upper and lower teeth do not align properly, overgrowth and spur formation can occur, causing eating difficulties and oral pain. Both incisors and molars can be affected.
Common symptoms
- Drooling or wet chin and mouth area
- Decreased appetite and weight loss
- Avoidance of hard foods
- Attempts to eat but appears unable to chew or swallow properly
Common causes
- Insufficient chewing due to inadequate hay intake
- Genetic jaw or tooth conformation
- Tooth fracture or displacement from trauma
- Age-related changes in dental alignment
Prevention (husbandry & daily care)
Providing unlimited high-fiber hay such as timothy at all times is the most important preventive measure, as it promotes natural tooth wear. Avoid over-reliance on pellets or soft foods. Regular weight monitoring and close observation of appetite and eating behavior enable early detection of changes.
