About Dental Malocclusion
Dental malocclusion in small mammals (rabbits, guinea pigs, chinchillas) occurs when continuously growing teeth (hypsodont dentition) fail to wear properly, leading to overgrowth, abnormal angulation, and oral pain. Unlike dogs and cats, these species' teeth grow continuously throughout life and require constant wear through fibrous diet to maintain proper length and alignment.
Category: Dental
Severity: Moderate
Symptoms to Watch For in Your American Guinea Pig
- Decreased appetite or selective eating
- Drooling (slobbers)
- Weight loss
- Facial swelling or abscess
- Eye discharge (upper tooth roots near tear duct)
- Inability to close mouth
- Grinding teeth (bruxism)
- Matted fur on chin
Causes
Genetic predisposition (particularly in dwarf rabbit breeds), insufficient dietary fiber (hay), trauma to teeth or jaw, metabolic bone disease affecting tooth development, and congenital jaw length discrepancies. Lack of abrasive food prevents normal tooth wear.
Diagnosis
Oral examination (may require sedation for full assessment). Skull radiographs or CT to evaluate tooth roots, jaw bone, and periapical disease. Assessment of occlusal surfaces for spurs, hooks, and abnormal wear patterns.
Treatment Options
Regular dental filing/burring under sedation to correct overgrowth. Extraction of severely affected teeth. Abscess management (debridement, antibiotics, pain management). Dietary modification to increase hay consumption.
Prevention for American Guinea Pig
Diet consisting of 80%+ grass hay for rabbits and guinea pigs. Providing appropriate chewing materials. Avoiding selective feeding of pellets over hay. Regular dental checks. Breeding away from severe malocclusion.
Prognosis
Mild cases managed well with regular dental care and diet correction. Severe cases with root involvement or abscesses carry a more guarded prognosis. Lifelong management typically required once malocclusion develops.
