What should I do if my guinea pig loses its teeth?

If your guinea pig loses one or more teeth it is necessary to help them, so pay attention to the following things:

These things are important when your guinea pig loses some teeth, so we will explain in detail what to do.

Do not reduce their remaining teeth

Never try to reduce the length of the remaining teeth to match the broken tooth.

Some owners make this mistake which can only make it difficult for the guinea pig to eat because then all the teeth will be reduced.

There is no need to reduce the rest of the teeth because the broken tooth will quickly grow and catch up with the other teeth.

Reduction of other teeth is done only when those teeth count against the broken tooth in its regrowth.

But for this kind of intervention, you must consult a veterinarian who will decide whether reduction of the other teeth is necessary.

Give them food rich in water

When guinea pigs have broken teeth, their biggest problem is chewing their food.

Therefore, it is necessary to give them food that is rich in water because then the guinea pigs may refuse to drink water due to broken teeth.

Food rich in water is the following:

  • cucumber
  • tomatoes
  • watermelon
  • melon

At the same time, cut them into small pieces so that the guinea pig can eat them more easily. Water intake is very important for the health and life of guinea pigs.what happens if a guinea pig loses its teeth

Here’s a more detailed explanation of each of these reasons so you know what to do to improve their teeth in terms of breaking them less.

Genetic problems

Some guinea pigs simply have genetically weaker teeth and are therefore much more likely to break them.

When genetics is the cause of frequent tooth loss, then you should consult a veterinarian who can partially help by prescribing vitamins to strengthen the bones, but do not expect that there will be ideal results.

When guinea pigs are injured by falling or hitting an object while running, this can lead to tooth loss.

That’s why you need to be careful where you let him play when he’s out of the cage and watch the toys in the cage.what happens if a guinea pig loses its teeth

Vitamin C deficiency

Vitamin C is one of the most important vitamins that guinea pigs need to have healthy teeth. lack of vitamin C, apart from causing teeth to break, also causes scurvy.

  • broccoli
  • tomatoes
  • cauliflower
  • parsley

When guinea pigs have a vitamin C deficiency, they start to be lethargic, have diarrhea, lose weight, and their fur becomes rough and dull.

Vitamin D deficiency

Vitamin D deficiency can cause guinea pigs to lose their teeth more easily. Since guinea pigs do not eat food of animal origin, they can get this vitamin from sunlight.

You can place the cage near the windows of your home or you can also use a UVB bulb so that they have more vitamin D.

It is enough for the guinea pig to be exposed to sunlight for 1-2 hours a day to get the necessary vitamin D.

How long do guinea pigs’ teeth need to be?

Guinea pig teeth should be about 1.5 cm or 0.5 inch in size. Their teeth grow an average of 7.5 cm or 2.9 inches per year.
