Teeth overgrowth happens when guinea pigs don't chew enough hay or fibrous foods. Hay acts like natural sandpaper, keeping teeth short and even. Diets low in hay and high in pellets or soft foods allow teeth to grow unchecked. Genetics also play a role, with some guinea pigs naturally prone to misaligned teeth (malocclusion). Injuries, infections or jaw problems may also cause uneven wear, leading to sharp points and painful chewing.
Wet fur around the chin or chest is often the first sign. Excess saliva is produced when teeth interfere with normal chewing.
If chewing becomes too painful, guinea pigs eat less and lose weight quickly. This is one of the most dangerous consequences of dental issues.
Abscesses can form in the mouth or jaw if sharp teeth cause injuries that become infected.
Overgrown tooth roots can push into sinuses, leading to watery eyes, nasal discharge or bulging eyes.
Guinea pigs may pick up food but drop it repeatedly or chew very slowly. Hard foods like pellets may be refused completely.
Affected guinea pigs may avoid hay or pellets and eat only soft foods, which further worsens the overgrowth problem.
Irritability, hiding more often, or less activity may indicate mouth pain. Some guinea pigs grind their teeth loudly from discomfort.
Because their teeth grow nonstop. If they don’t wear down naturally with hay, teeth become too long and block eating, or cause painful injuries in the mouth.
Look for drooling, weight loss or difficulty chewing. If you see wet fur around the chin, food being dropped or refusal to eat hay, it’s time to see a vet.

Your guinea pig may stop eating, lose weight, develop painful sores or even die from starvation. Overgrown teeth can also cause abscesses and jaw problems.
