What is Molar Malocclusion?

Molar Malocclusion is a very serious health problem for guinea pigs. This is a situation in which, through a combination of genetics, poor diet (i.e. insufficient fiber), and lack of chewing opportunities the rear molars become overgrown.

In a normal, healthy guinea pig these molars meet in the middle and wear each other down. In malocclusion, the lower molars curve inward and trap the tongue, and the upper molars curve upward and penetrate the roof of the mouth. This condition creates the effect of 'slobbers', in which the guinea pig drools constantly, and eventually cannot eat. THIS IS AN EMERGENCY SITUATION! If left untreated, the cavy can starve/dehydrate, and if treated too late it may not regain function of the damaged tongue.

This situation is arising more often, partially due to nutritional misinformation and a diluted genetic pool. A guinea pig should visit a knowledgeable veterinarian regularly who can evaluate the rear molars and trim them into normal occlusion if necessary.
