Broken teeth

If the baby guinea pig is often exposed to unfortunate injury situations, their teeth may break.

If they are deficient in vitamin C again this can be the cause of their teeth breaking.

That’s why it is necessary to make sure that the diet always has enough vitamin C and that you take care that your little guinea pig is not hit, especially when you let him out of the cage.

My guinea pig makes popcorn when I let him out of his cage and hit him uncontrollably hard objects like chairs and tables.

In any case, if the baby guinea pig is healthy, its broken teeth will grow back.

Malocclusion or misalignment of teeth

If the baby guinea pig has irregular teeth and if they are overgrown then they have malocclusion or irregularity of the teeth.

The more time passes, the worse the malocclusion will affect the baby guinea pig’s teeth.

Malocclusion can cause additional problems such as injuries, wounds, and infections, so you must take the little guinea pig to the vet.

Problems with the roots of the teeth

Baby guinea pigs may have teeth with open roots that are growing all the time and can be pushed and grow towards the jaw.

In this way, there is an appearance of elongated roots, and this is noticed by the protrusions on their lower jaw.

The easiest way to tell if a baby guinea pig has this problem is to look at their eyes because if they are bulging it is a sign that they have dental problems.

Why do baby guinea pigs lose their teeth?

Most often, baby guinea pigs lose their teeth due to vitamin C deficiency.

When they do not have enough vitamin C, they can get scurvy, which is a dangerous disease for their health and life.

Guinea pigs can only get vitamin C through their diet, so you should always ensure that this vitamin is present in their daily diet.

Your pet can also lose their teeth if they chew on very hard materials or objects.

They will grow back but as they grow your guinea pig will have trouble eating the food.

How long does it take for guinea pig teeth to grow?

The teeth of guinea pigs grow constantly, or on average about 7.5 cm per year.

Because their teeth are constantly growing, the actual length of their teeth cannot be determined.

When the guinea pig is healthy and everything is fine, the incisors as the main teeth are about 1.5 cm long, so they wear out and grow again all the time.

Do guinea pigs feel pain in their teeth?
