Guinea Pig Teeth: A Guide To Guinea Pig Dental Care

Pet guinea pig has become a phenomenon among pet owners due its cute size but their miniature size makes it very hard for their owners to identify any teeth related issues and disease they would have.

Constantly Growing Teeth And Dental Issues

The main thing you need to know about guinea pigs’ teeth is they are always growing. As humans our teeth keep on the same size and shape throughout our life time but guinea pig’s teeth can be considered as overgrown teeth because they usually grow 1 to 2 mm per week. There is an interesting reason behind this. Their teeth get worn down by fiber which includes in their diet. Because of that the teeth have to keep growing otherwise the teeth will disappear from its mouth.

Our rodent pet is not the only one who has this kind of teeth which is commonly known as open rooted teeth. Small herbivores such as rabbits, chinchillas and degus also have them though guinea pigs don’t have many teeth as rabbits. A guinea pig has 20 teeth while a rabbit usually has 28 teeth.

If you are a cavy owner you need to make sure that your guinea pig’s diet includes enough plant particles. If not teeth will not wear out appropriately and this could result teeth to grow in the wrong path or too long.

In front of mouth, guinea pigs usually have two long slender incisors on both their lower jaw and upper jaw and they also have four cheek teeth.

When guinea pigs teeth are not able to wear off by chewing enough grass or timothy hay, they could become overlong teeth with the time.

The most general dental disease with guinea pigs is elongation of their cheek teeth. The mandibular incisor tooth is the worst affected when compared to others and they can grow so long and trap the tongue as well. This could cause more health issues as your piggy will not be able to eat properly because this entrapment prevents the tongue from normal movements.
