Guinea Pig Dental Disease Prevention and Care

Dental disease is extremely common in guinea pigs and a major cause of suffering, often going undetected until animals are seriously ill.

Key Facts

Guinea pig teeth grow continuously and must be worn down by appropriate diet
Malocclusion causes tooth spurs that lacerate the tongue and cheeks causing pain
Dental disease often presents as weight loss rather than obvious pain signs
Diagnosis requires specialist examination often under sedation to assess back teeth
High-fibre diets with unlimited hay prevent most dental problems
Regular weight monitoring is the most practical welfare check for dental problems

Welfare Considerations

Dental disease causes profound suffering in guinea pigs that often goes unrecognised because prey animals hide illness. By the time outward signs appear - weight loss, reluctance to eat, wet chin from drooling - disease may be advanced. The majority of guinea pig dental problems are preventable through appropriate diet. A diet based on unlimited hay provides the abrasive wear needed to maintain dental health. Once malocclusion develops it typically requires regular specialist dental treatment under anaesthesia.

What You Can Do

Ensure guinea pigs have unlimited access to hay as the foundation of their diet
Weigh guinea pigs weekly to detect early weight loss before dental disease advances
Have guinea pigs examined by a small mammal specialist at least annually
Seek veterinary assessment promptly for any reduction in food intake or weight
