They usually have a set of incisors and cheek teeth in each jaw. Guinea pigs have 28 teeth in total which is the number in both the upper and lower jaws involved in chewing food before swallowing it. The guinea pigs love to chew on anything they can get their mouths around, including electric wires!

The names given to the teeth are:

Incisor– There are six of them at the front of each side of the mouth. One on top and one on the bottom for a total of 12.

Molar -There are three molars on either side of each jaw, for a total of 12 molars.

Premolar – There is one premolar on top and one on the bottom of each jaw, for a total of six premolars.

Fun Fact: Guinea pigs don’t have upper incisors, meaning that they can’t chisel and cut food. They must first mash their meals with their lower front teeth before swallowing them.

Which way do Guinea Pig Teeth point?

The incisors point forward-facing downwards normally, while the cheek teeth point outwards and downwards. So they can still grind food with their molars even if they can’t with their lower front teeth.

Looking closely at the mouth of a guinea pig, you can see that as their lower jaw is rotated outwards while those in charge up top are pointing upwards almost like with rabbits.

This makes it easier for them to keep their teeth clean by side-to-side grinding instead front tooth backs and forth motion we use when eating or talking; which might be partly why they seem so sweet despite having such sharp incisors!

Guinea pigs have teeth that look a lot like ours, with one exception.

The cheek teeth are not paired but rather there is on top and below like humans only smaller – they’re called premolars or molars ( GuineaPigs also have 4 upper cheek tusks/toes on either side of their jaw while we usually just see 3 pairs).

These spade-like shapes fit so perfectly into each other it’s hard to tell where one ends and another begins!

Guinea Pig Teeth Growth Cycle

The guinea pig teeth grow slightly longer as they are being used to chew food, which is why it’s important for them to have a constant supply of appropriate things in order to keep them from possibly trimming or curving their incisors!

If the animal doesn’t gnaw continuously on something sharp enough then its canines may curve and grow into an unhealthily angled position.

I love giving my guinea pigs things to chew on, like twigs and hay – it keeps their teeth in good shape.

If they start to bleed, get caught on the bars of their cage, appear overgrown or make your guinea pig uncomfortable then it is time for a check-up with a trained vet that can trim them back.

Guinea pigs may also eat less and drop weight if their teeth grow too far causing them discomfort.

Common Symptoms include:

  1. Drooling frequently
  2. Not eating for a long time
  3. Not carrying food to their mouth – even when it’s their favorite food
  4. Not cleaning themselves
  5. Lastly, they also sit with their mouth open looking like they’re grinning – these symptoms mean you might need to take them in for a check-up at the vet 

How often do their molars grow and how fast?

Guinea pig’s first molars come through at around 10 weeks old and usually last until 4-6 months of age depending on the guinea pig.

Their second molars usually appear from 5 months and last until 10 months. How fast they grow depends on how often and what they chew on.

They use their tongues to nudge and grind the food against their lower front teeth and molars. So they ‘chew’ their food with their tongues, not with their teeth.

Guinea Pigs have a hard time eating leafy greens because their tongues are not designed for this.

Even though they can eat them, it’s much more difficult and often ends up with the Guinea Pig spitting out what she doesn’t chew properly or even choking on her food while trying to do so.

You should learn how to spot the signs of dental issues and seek advice from a trained vet if you think your guinea pigs’ teeth need attention, but here is how it’s done:

First of all, find some small treats that your guinea pig loves. It could be something like fruit or veggies or special hay cubes. Then hold open their mouth with one hand while using the other to give them the food inside.

It may take a few tries but eventually, they will learn what this means and associate it with getting fed – hopefully making it easier for you to do in the future!

When they open their mouth and accept the painless treat, hold it closed and use a pair of pliers to grip any visible tooth firmly.

Slowly push down on the tooth until you feel resistance and then rock the plier back and forth until you hear a cracking sound.

Release your fingers from their mouth as soon as possible so they realize this isn’t food or fun – otherwise, they may snap at you if they think it is food

General upkeep: You should check your guinea pig’s teeth now and then make sure nothing looks overgrown or strange, but the only attempt trimming those that look visibly out of place or causing discomfort.

You can gently lift up their lips and shine a light into their mouths to check them, but if you’re unsure take your guinea pig to a vet.

Cavies (guinea pigs) have a total of 28 teeth that to this, cavies only have the ability to chew on one side need to be maintained, particularly by cutting their incisors, which can grow six inches a year and prevent them from chewing food properly. In addition to cutting their teeth, cavies also need to keep their teeth ground down by chewing on wood blocks or sticks.

Guinea pigs’ teeth are open-rooted, which means that they continue to grow throughout the life of the animal, at about six inches (15 cm) per year.
