Guinea Pig Teeth, Dental Disease, And Dental Care

Do all guinea pigs come with teeth that grow continuously? Guinea pigs’ constantly growing teeth are also “elo-don’t” dentitions. They have incisors and front teeth, which keep growing if you don’t check them regularly. Their unique sense of having ever-growing dentition is unique. Guinea pig teeth are similar to human nails. It’s essential to introduce them to biting and chewing methods. This helps in managing the growth of their teeth. The overgrown teeth in Guinea pigs lead to painful dental issues.

What’s Special About Guinea Pig Teeth?

Ever Growing Teeth:

Guinea pigs belong to the rodent family known as Caviidae. Similar to the rodents, Cavies are elodonts, a condition where the teeth grow continuously. The teeth do not stop growing during the entire lives of Guinea pigs. If they fall out, the teeth will grow back. They have a total of 20 teeth.


Cavies feature four long, thin teeth in front of the oral cavity. These teeth are known as incisors. There are two upper incisors and two lower incisors. The incisors are the teeth that help them grab food. They are also meant for grooming purposes. Behind guinea-pig incisors, instead of canine, there is a diastema, a gap between the premolars and incisors.


Cavies have around 4 upper and lower premolars, two on each side. Premolars come after the incisors and next to the molars. Removal of the teeth helps grind the food that Guinea pigs usually survive on.


Next to the premolars, there are around 12 molars. These molars are utilized for heavy-duty grinding. Again, molars are for chewing food, and that too in bulk. There are around 6 molars on each side of the oral cavity 3 upper and 3 lower. Molars are also ever-growing and develop for the entire life.

Guinea Pig Dental Problems:

Guinea pig’s teeth have open roots. They have long-rooted teeth, which can result in several dental issues like malocclusion or broken teeth. However, most of the  Guinea pig’s dental problems can easily be treated.

Tooth Loss:

Tooth loss is mainly because by Vitamin C deficiency in guinea pigs’ diets. This results in broken teeth. Apart from it, there is a deficiency of calcium and Vitamin D in guinea pigs resulting in broken teeth. These minerals are essential for strengthening muscles, teeth, and bones. As Cavies are elodonts,  there is a high chance their teeth will grow in different directions. This results in pressure on surrounding teeth leading to a painful impact for Guinea pigs. It is therefore essential to get guinea pigs checked regularly.  If there is tooth loss, it is essential to get it checked for the formation of blood clots.

Elongated Roots:

Elongated roots in Guinea pigs press other teeth around, leading to a painful jaw. A dental examination helps in finding out this condition. The jawline at the bottom might have bumps which tell us whether Guinea pig’s teeth have long roots or not.


Malocclusion indicates that there isn’t a proper alignment of teeth in guinea pigs. This can cause several issues like less wear of teeth and deterioration of oral health. If Guinea pigs swallow their food without undergoing any grinding process, this will result in a lack of wear over the teeth. When malocclusion results, teeth move in various directions. For instance, upper molars move towards the inner side of the cheeks.

On the other hand, lower molars will affect the tongue, causing pain for Cavies. This results in improper closure and opening of the mouth. In addition, incisors might overgrow, leading to malalignment and affecting the growth of premolars. This can cause abscesses, sores, or infections within the Guinea pig oral cavity.

Development Of Spurs:
