Why Do Chinchillas Grind Their Teeth[4 Common Reasons]

If you have recently decided to adopt a chinchilla, you may be curious why they are grinding their teeth or making any form of a teeth-chattering noise.

That is expected and it is a common question to ask at the beginning of owning your new chinchilla.

While chinchillas make excellent pets, it can still be confusing in the beginning.

Why do chinchilla grind their teeth?

I have now been raising a chinchilla for the past 5 years and here is what I can tell on this topic.

Chinchillas often grind their teeth due to several factors. Chinchillas can grind their teeth because of stress, the pain they are experiencing, and some chinchillas will grind their teeth for no apparent reason at all. Chinchillas may also grind their teeth to express emotions such as happiness.

Why Do Chinchillas Grind and Chatter Their Teeth?

While chinchillas are one of the most social and friendly creatures we can adopt and own, this doesn’t stop them from sending us mixed signals from time to time.

Often, after owning a chinchilla for a long time, things become easier to understand.

However, circumstances still arise when it’s not always so easy to figure out why your chinchilla is doing one thing or another.

A chinchilla grinding teeth is undoubtedly one of these behaviors which can leave new or experienced chinchilla owners confused and not sure what to do next.

Let’s re-emphasize some of the common reasons why your chinchilla may be grinding their teeth.

First and foremost, if your chinchilla is currently grinding their teeth, don’t panic.

It’s just as likely it’s nothing to worry about, but at the same time, it could be something worth looking into.

Again, we have a few common reasons why chinchillas will choose to grind their teeth.

Here’s a look at the reasons I’ve compiled from raising my chinchilla or from additional research and speaking with other chinchilla owners in Facebook groups or online communities.

These are the top 4 reasons I’ve put together for a chinchilla grinding their teeth in my experience.


Top 4 Reasons Your Chinchilla Will Grind or Chatter Their Teeth

Below, I plan to illustrate the top 4 reasons your chinchilla may be grinding their teeth and then provide a detailed summary and give possible solutions you can try to put an end to the teeth grinding.

Reason #1 For Chinchilla Teeth Grinding- Stress

Stress can be the primary reason why your chinchilla is grinding their teeth.

This can also be for several different reasons.

It usually will occur when adjusting to a new environment.

For instance, when you are bringing your chinchilla home for the first time, changing your chinchillas’ room where their cage is located or changing homes altogether.

Chinchillas are very particular about their surroundings and are creatures of habit.

They need cold temperatures and quickly get used to their surroundings including what they can smell, what they can hear, and even what they see.

If your chinchilla is frightened by a new environment, it’s possible your chinchilla is grinding their teeth.

When this takes place, do your best to comfort your chinchilla.

Get your chinchilla out of their cage and interact with them as much as possible.

Attempt to interact and handle them in calm manners.

Don’t fear or stress about handling and interacting with your chin, a chinchilla will not bite in most circumstances (although it is possible).

The point I am trying to make here is simple.

If you notice your chinchilla grinding their teeth and you are relatively certain that it is due to stress, do your best to accommodate.

Make sure they seem comfortable in their environment and reduce the stress as much as possible and see if the teeth grinding eventually comes to an end.

Take Things Slow and Give It Time

Additionally, allow them to get to know their environment more frequently.

Maybe for the first few weeks, you clean their cage more often and let your chinchilla come out for dust baths during this time.

The more your chinchilla can get used to their environment, the sooner you can put an end to the teeth grinding if this is, in fact, the direct cause that your chinchilla is grinding their teeth in the first place.

Additionally, give your chinchilla time in this situation to allow their anxiety and stress levels to drop.

Sometimes it happens very quickly, and sometimes it can take weeks or even months.

Respecting your chinchilla’s space and feelings during this time is imperative.

Another big thing you can do to help your chinchilla adjust more quickly to being in a new home or getting used to you as the owner is considering a chinchilla playpen.

This allows for a smaller, safe space for your chinchilla to interact and get to know you.

It also reduces/eliminates any need for you to fully chinchilla proof a room for your chinchilla to play inside of.

I believe chinchilla playpens are highly-underrated and do a fantastic job at building a bond with your chinchilla much faster and making them much more comfortable.

This, in turn, may reduce the stress and the teeth chattering taking place.

I currently use the Jespet 61 inch (Link to Amazon)

I have been using it for 4 years now and have had zero issues with it.

If your chinchilla is grinding their teeth and the stress seems to be the cause with no end in sight, consider a chinchilla playpen to help with this issue.

Reason #2 For Chinchilla Teeth Grinding- Illness or Pain (Tooth or Non-Tooth Related)

Now for the bad news.

Sometimes your chinchilla will grind their teeth due to an illness or overgrown teeth issues.

Therefore, it’s so important always to allow your chinchilla the ability to chew and file down their teeth.

Chewing on chinchilla safe toys is what will enable chinchillas to naturally grind their teeth down and keep their teeth healthy.

If your chinchilla isn’t grinding their teeth and you are merely completing early research in case it ever happens in the future, you can help avoid this problem providing your furry friend some safe chinchilla toys to chew in their cage.

Hay cubes and wood sticks are some of the chinchilla’s most desired items to chew.

Just be careful when they are out for playtime.

Chinchillas love to explore, jump and climb.

You need to make sure the room is safe, and your chinchilla can’t access dangerous items that they could chew such as electrical cords or wires.

You also want to ensure that the wood items you offer your chinchilla are safe.

Be Proactive If You Believe Your Chinchilla Is Grinding Their Teeth Due to Illness

Lastly, if your chinchilla is grinding their teeth and you don’t believe it’s a tooth issue but some other pain causing the grinding, you need to contact a vet.

Chinchillas with illnesses tend to get worse more rapidly, so it’s essential to be proactive.

Often if your chinchilla has teeth related health issues, you will be able to notice an odor emitting from your chinchilla.

Again, breathe easy.

Chinchillas will not emit odor unless this is the circumstance.

Chinchilla’s poop and pee like other rodents.

However, they remain odorless if you take care of them.

And of course, clean their cage an adequate amount of times per week.

Reason #3 For Chinchilla Teeth Grinding- Boredom and No Real Good Reason

Now back to some good news.

Sometimes your chinchilla may just grind their teeth for no good reason at all.

This can be because they are bored.

If this is the case, you likely need to either get your chinchilla a new chinchilla mate to interact with or spend more time with your chinchilla.

Chinchillas are very social and friendly animals and can get bored or irritated with you quickly.

Socializing a chinchilla is an important step after the adoption.

If you notice your chinchilla grinding their teeth, with no odor, and see no other behaviors from your chinchilla, it could be no one’s fault except your own causing your chinchilla to grind their teeth.

Spend more time with your chinchilla and give your chinchilla large enough cage to stay active and having fun, so they don’t enter these depression sessions of boredom.

Reason #4 For Chinchilla Teeth Grinding- Communication and Sending You A Message

Now, this reason resembles reason number #3 in many ways.

We just discussed how your chinchilla may be grinding their teeth because they aren’t being socialized or interacted with enough.

Now, let’s assume you are getting your chinchilla out for playtime and making them do all their natural chinchilla type behaviors.

If this is the case and you notice teeth grinding during specific interactions such as when you attempt to hold your chinchilla, they may be sending you a message that they are annoyed.

One way to make this better is to start by learning how to get your chinchilla to enjoy being held.

Don’t’ take this the wrong way.

They love you and recognize you as the owner, but they have things to do when they are out for playtime.

They want to jump, climb, and explore during their short spurts of time out of the cage.

If you keep interfering with what they want to do, they may only be letting you know a straightforward message “I love you, but I have things to do.”

If this is the case, let them out in a safe area and let them do their thing.

Learning how to recognize your chinchilla’s body language and what they are trying to communicate will get much easier as time passes.

Don’t fret it much now.


How to Easily Tell Which of the 4 Reasons Is Causing Your Chinchilla to Grind Their Teeth.

Unfortunately, chinchillas aren’t that easy in this respect.

Chinchillas are a straightforward animal to care for but recognizing body signals and body language can be a bit trickier with chinchillas.

The easiest way I can think of to narrow down the cause for teeth grinding is to pay attention to your chinchilla’s odor and behavior.

If your chinchilla is emitting an odor, sleeping more than average, or seems agitated much more often than usual, there is a strong likelihood that it’s time to contact your vet.

Take your chinchilla in for a visit.

It could be something more serious going on with your chinchilla if this is the case.

However, if your chinchilla is behaving normally, eating, drinking water, pooping and nothing much has changed, it’s likely it’s one of the other three reasons causing your chinchilla to grind their teeth.


Chinchilla’s Grinding And Chattering Their Teeth Does Not Necessarily Cause For Concern

Like I’ve stated during this entire post, chinchillas can be challenging to understand with certain behaviors, and some teeth grinding or teeth chattering should not necessarily alarm you.

It’s the nature of owning a chinchilla, and they are still undoubtedly excellent animals to own.

I have no regrets about owning my chinchilla.

Be willing to find the root of the problem and adjust your routine to attempt to put an end to teeth grinding with your chinchilla.

Chili and I wish you the best of luck with your new chinchilla and the journey you have ahead of you.
