Common Baby Guinea Pig Dental Problems

Sometimes, even regardless of taking care of your baby guinea pig’s teeth, your little pet can fall prey to any one of these following diseases.


Elongated Roots

Baby guinea pigs have open-rooted teeth that are continually growing. Sometimes, the roots of your pet’s teeth can get pushed up and start growing inside their jaw. This is how elongated roots are caused.

The problem is that even an oral examination does not reveal this. However, if they have elongated roots, you will notice certain bumps in their lower jawline.

The key to finding out whether your baby guinea pig is experiencing elongated roots is to keep a check on their eyes. If their eyes are bulging or tearing, it can be a sign that the roots of their top teeth aren’t growing correctly.



Malocclusion Guinea Pig Teeth

Teeth that aren’t worn out properly and are overgrown are known as maloccluded teeth. Even though it seems like only the front teeth are being affected, in fact, both the front and the back teeth are affected at the same time.

As this oral problem gets worse, the ability of your baby guinea to chew will gradually deteriorate. Moreover, their front teeth won’t be receiving a reasonable level of wear, which is necessary.

Malocclusion can also cause infections, injuries, and sores in your baby guinea pig’s mouth, making it difficult for them to lose weight.

Baby guinea pigs are often susceptible to broken teeth due to various reasons, such as accidents and lack of Vitamin C. If your baby guinea pig is normal and healthy, the damaged or lost tooth will grow back relatively quickly.
