A Guide to Guinea Pig Teeth | All You Need to Know About Guinea Pig Dental Care!

Dental care is very important for both humans and animals. For guinea pigs, stinky breath usually means that there’s a problem with either stomach or teeth.

What are guinea pig teeth? Teeth are very important organs in your guinea pig’s body. They use their teeth to grind some hay or any food you give to them. As such, they should be treated well and with care. If you notice that your guinea pig has some problems with its teeth, you should definitely take it to the nearest vet.

This article is here to inform you about guinea pigs and their teeth. We’ll talk about everything from typical dental problems to their teeth in general. If you’re willing to learn something new, let’s start!

Guinea Pig Teeth | What You Need to Know

Guinea Pig Teeth

Guinea pigs have 20 teeth. The middle two at the front and the bottom are incisors. Other teeth include premolars and three pairs of lower and upper molars.

Unlike many predator animals, guinea pigs don’t have canines. It means that they can’t slaughter an animal like a lion would do. This goes hand to hand with guinea pigs, though. As they’re herbivorous animals, they don’t need two pairs of canines.

Between their upper and lower incisors, they have a tiny gap. This gap is called a diastema. It’s also important to mention that their teeth are open-rooted, meaning that they’ll grow indefinitely.

Preventing their teeth from growing further is simple – get some food! When guinea pigs chew, they don’t only remedy this problem but also take care of their dental health, which is crucial for an animal like this.

Still, their front teeth are very sharp and can easily chew down things like your furniture. That being said, don’t let your guinea pig chew everything it sees. It’s important to mention that guinea pigs’ teeth should be white, which represents a healthy color.

What If Your Guinea Pig Refuses to Eat?

What If Your Guinea Pig Refuses to Eat

The experienced guinea pig owners know that guinea pigs sometimes just won’t eat. One time, they’re full and they can’t take a single bite. Other times, it may be a digestion problem or simply a dental problem.

In the case of digestion problems, the symptoms can almost always be seen. However, dental problems can be latent as guinea pigs don’t flinch when they feel the pain in their mouth.

In the case its appetite ceases, you should always consider dental problems. It can go so seriously that guinea pigs can develop anorexia. In guinea pigs, anorexia represents a severe loss of appetite. The loss of appetite leads to weight loss.

If your guinea pig refuses to eat for a couple of days, taking it to a vet is very important. In fact, if it doesn’t eat a day or two, it’s a reason for concern. The vet will then determine if your guinea pig is having digestion, dental, or any other problems.

What Dental Problems Can Guinea Pigs Get?

Unfortunately, guinea pigs can suffer from various dental problems. But, on the brighter side, there are only a couple of them which are the most common and most of them can be fixed relatively easily. Here they are:

1. Tooth Loss and Broken Teeth

Guinea pigs can break their teeth, much like humans. In humans, breaking a tooth is much harder and requires some serious pressure. In guinea pigs, it’s very easy if the diet isn’t good and is lacking vitamin C.

If you thought that only vitamin D and calcium are great for your bones, vitamin C works like a charm! That’s why incorporating a bit more vitamin C in your guinea pig’s diet is crucial. However, let’s not blame the diet completely, as broken teeth can be an effect of the injury.

If your guinea pig is healthy, both broken or lost teeth shouldn’t be a problem. It will easily grow again. However, some problems can occur and it can start to grow in a different direction, pushing other teeth, which can be very painful for guinea pigs.

When you see a lost tooth, examine its root. If there’s blood inside, be sure to flush it out and disinfect it. A tooth infection is very dangerous and can produce abscess, which can make your guinea pig’s mouth swollen.

2. Elongated Roots

The rooted teeth of guinea pigs sound like an ideal situation. They grow bigger by the day, much like rabbits. But, guinea pigs can suffer from a condition in which their roots are elongated.

When the root is elongated, it means that it’s pushed up, which can make the tooth grow into the jaw. The worst thing is that the oral examination can’t bring up any results. Instead, you can feel it under the palm of your finger. In the bottom teeth, touch the jawline and you should feel bumps.

For the upper teeth, it’s quite easy to notice it by examining the guinea pig’s eyes. If they’re teary, it can definitely indicate that teeth are making the problem. Thankfully, you can still do an X-ray to fully determine if you’re right.

This problem, in most cases, can’t be fixed directly. But, if it’s an early stage of the condition, a vet might give you a chin sling. It’s sort of a contraption that’s attached around the jaw with some straps.

3. Malocclusion

Malocclusion is a state in which guinea pig’s teeth are overgrown and not worn properly. It can easily be spotted by looking at the front teeth. However, while it may seem that only front teeth are maloccluded, in most cases, the back teeth are also in a trouble. If not treated on time, malocclusion can produce some serious problems for your guinea pig.

For example, the teeth can deteriorate over time, alongside the ability to chew. Without chewing stuff, guinea pigs can’t receive a healthy amount of wear that keeps their teeth healthy.

Malocclusion can also interfere with the guinea pig’s teeth growth. In most cases, top molars will grow towards the cheeks, while the bottom molars usually grow in the direction of the tongue. This condition causes injuries, infections, and sores in the guinea pig’s mouths, which can be a very unpleasant experience.

Coupled with the fact that your guinea pig will lose weight if it doesn’t eat properly, the lack of various macronutrients and micronutrients will definitely take a toll on the poor guinea pig.

Here are some signs which can determine if your guinea pig has a problem:

  • Sudden weight loss
  • Guinea pig refuses to eat
  • Difficulties with chewing or chewing on one side of the mouth
  • The mouth of the guinea pig is constantly open
  • Discharge from nose or eyes

If you notice some of these, be sure to visit the vet as soon as possible. The vet will then take your guinea pig to an X-ray and determine the cause, as well as the presence of the problem.

Usually, maloccluded teeth can be easily spotted through x-ray. If a malocclusion is severe, your guinea pig will need dental work every month to get the job done.

First of all, you want to take a look at its incisors. Although they look very small, they’re in fact the biggest teeth in your guinea pig’s mouth. With the ability to grow up to 1.5 centimeters, their roots are located deep inside the guinea pig’s mouth.

If you move its mouth a little bit, you can see the whole incisors, which is a great sign. When a guinea pig eats normally and shows no signs of appetite loss, its teeth should be worn down with the food.

However, incisors should be intact and their length should match. Guinea pigs also have molars and these teeth are a lot harder to come by. Not only they’re far inside the mouth but they are also very small.

Examining the molars by yourself is probably not the smartest idea. On top of that, some amount of food can get there and it’s even harder to see them. If you really want to check the molars, visiting your vet is the best bet. With the special tools that they have, examining should be a piece of cake and any needed intervention can be done in a matter of seconds.

Moreover, guinea pigs love to chew everything, similar to other rodents. However, guinea pig’s teeth are sometimes fragile and can break when they chew something hard. This is why checking your guinea pig’s mouth often is imperative.

In case it has a broken tooth, you’ll need to take it to the vet. The vet will determine if they need to do something and in most cases, this tooth will need to be trimmed or filled to be even again. Sharp edges of the teeth can damage the guinea pig’s mouth and lead to some serious trouble.

Recommended Food for Guinea Pig’s Dental Health

Diet, in most cases, is the number one reason why your guinea pig’s teeth are beaten. That is why a proper diet is very important, for both guinea pigs and humans.

People can’t grasp just how healthier we can be if we stick to healthy food and evade sugars and fats altogether. Back on the topic, guinea pigs will need a lot of fibers in their diet, a bit fewer calories, and some high-quality grass and hay every day.

While the quality diet can’t guarantee that your guinea pig will be always healthy and without problems, it can decrease the chances of any problems by a huge percent.

Moreover, pelleted food will often be designed in a way that complements hay and grass thus helping your guinea pig to wear down its teeth. Some tree branches are also great but have in mind that some of them are full of chemicals and pesticides. Aside from that, you can always include some salt or mineral blocks.

Salt blocks will give your guinea pig a healthy amount of calcium and other minerals, as well as vitamins if you’re planning to buy enriched salt blocks. If you’re not sure what salt blocks to give it, you can always talk with the vet about that.


Be sure to examine the teeth once a month or even better, take it to the vet for a preventive examination. It’s better to detect potential problems on time than having to put your guinea pig through tremendous pain.
