Cat Teeth Grinding: Warning Signs Every Owner Must Know in 2025
My journey into understanding cat teeth grinding started when I discovered something alarming about my own cats. The moment I learned that 75% of cats over five years old suffer from tooth resorption, I knew I needed to pay closer attention to my feline friends’ dental health. This painful condition often leads cats to grind their teeth – a sign I’d previously overlooked.
Watching my cats closely taught me that teeth grinding or chattering isn’t just a quirky behaviour to ignore. Regular vet check-ups can spot 85% of oral diseases causing this issue. What surprised me most was learning how these dental problems could signal bigger health concerns, from simple tooth decay to more serious conditions like pancreatitis.
Let me share what I’ve learned about cat teeth grinding from caring for my own cats. Together, we’ll look at the warning signs you should watch for, understand what causes this behaviour, and learn how to protect your cat’s dental health. My experience might help you spot problems early, saving your cat from unnecessary pain and discomfort.
Understanding Cat Teeth Grinding Basics
My vet first explained to me that cat teeth grinding, or bruxism, looks quite different from normal chewing. Instead of the usual up-and-down motion I see when my cats eat, grinding involves unusual side-to-side jaw movements [1]. This puts extra pressure on their TMJ – that’s the joint connecting their skull to their lower jaw [1].
What is bruxism in cats?
I’ve learned that cats don’t just grind their teeth for no reason [2]. When my cats developed this habit, I noticed they made distinct clicking sounds while moving their jaws [3]. My vet explained this usually means they’re hurting somewhere – it could be their teeth, tummy problems, or sometimes even brain-related issues [3].
Normal vs abnormal teeth movements
When I check my cats’ mouths during their health checks, I make sure their teeth line up properly when they close their mouths. Some of my Persian-owner friends struggle more with this – their cats’ flat faces often cause tooth alignment problems, just like Siamese cats with their longer faces [3]. Here’s what I look for:
| Normal Movements | Abnormal Movements |
|---|---|
| Smooth chewing | Side-to-side grinding |
| Easy food pickup | Difficulty picking up food |
| Comfortable jaw closure | Painful mouth closing |
Why cats chatter their teeth at birds
My cats do something completely different when they spot birds through our windows – they chatter their teeth [4]. It’s fascinating to watch:
- Their jaws move quickly with clicking teeth
- They make soft, high-pitched sounds
- Their ears point forward, totally focused
I used to think they were just excited or frustrated about not catching the birds [5]. But recently, I read something fascinating – scientists think cats might actually be trying to copy their prey’s sounds [6]. They discovered this after watching Brazilian wildcats mimicking monkey calls while hunting [6].

Early Warning Signs to Watch For
Living with multiple cats has taught me to spot teeth grinding signs early. My oldest cat showed me just how subtle these warning signs can be, and now I know exactly what to watch for.
Changes in eating habits
I first noticed something was wrong when my cat Max started acting oddly around his food bowl. He’d rush to eat but then struggle with his kibble [3]. Soon after, I spotted him dropping food while eating, and he started avoiding his dry food completely [7]. The most telling sign was when he began tilting his head sideways to eat – a clear sign he was trying to avoid pain [7].
Behavioural changes
My usually friendly cat suddenly showed dramatic personality changes. Here’s what I noticed:
- He’d get cross when I tried to pet him
- He stopped joining us in the living room
- He found new hiding spots under furniture
- He barely played with his toys anymore [8]
Sometimes, teeth grinding from stress can show up differently. My younger cat started having toilet accidents and would tremble when stressed [7].
Physical symptoms to monitor
These physical signs made me realise it was time for a vet visit:
| Symptom | What to Look For |
|---|---|
| Drooling | Excessive saliva, often accompanied by pawing at mouth |
| Oral Issues | Bleeding gums, facial swelling |
| Grinding Sound | Low to loud clicking noises from jaw |

Common Causes of Teeth Grinding
My years of cat ownership have taught me that dental disease is the biggest reason cats grind their teeth. My vet explained that this affects between 50% and 90% of cats over 4 years old [9]. Let me share what I’ve learned about these causes to help you spot problems early.
Dental disease and oral pain
I was shocked when my vet told me that tooth resorption affects about 75% of cats over five years old [3]. My cat Bella suffered from this – her teeth started dissolving from the inside out. Through her experience, I learned about several dental issues:
| Dental Issue | Impact |
|---|---|
| Gingivitis | Inflamed, painful gums |
| Tooth Resorption | Gradual tooth dissolution |
| Periodontal Disease | Tissue and bone damage |
| Malocclusion | Misaligned teeth friction |
Stress and anxiety factors
While dental problems are most common, I’ve noticed my cats sometimes grind their teeth when stressed. My cat Luna started this habit when we:
- Moved to our new flat
- Adopted another cat
- Changed her feeding schedule
- Started treating her arthritis
Medical conditions
Through caring for multiple cats, I’ve discovered that teeth grinding can signal other health issues too:
| Condition Type | Examples |
|---|---|
| Gastrointestinal | Pancreatitis, IBD, ulcers |
| Neurological | Seizures, brain tumours |
| Systemic | Low potassium, vitamin deficiencies |

| Keep dental records | Delay veterinary visits |
My experience has shown me that understanding these causes helps spot problems early. I now know exactly what to watch for in my cats’ behaviour and when to seek help.
Essential Home Dental Care Tips
My vet shocked me when she said 50-80% of cats over four years old develop periodontal disease [10]. Since then, I’ve made dental care a priority for my cats, and I’d love to share what works for us.
Daily tooth brushing techniques
Teaching my cats to accept tooth brushing wasn’t easy, but I’ve developed a method that works brilliantly:
- I start by gently touching around their mouths during cuddles
- Next, I let them taste and smell cat toothpaste from my finger
- Then, I introduce their special cat toothbrush
- Finally, I brush at a 45-degree angle to clean teeth and gums properly [11]
One mistake I made early on – never use human toothpaste! It contains ingredients that can make your cat seriously ill [11].

Creating a dental care routine
My cats taught me that consistency beats perfection every time. Here’s what works for us:
| Do’s | Don’ts |
|---|---|
| Brush daily or at least twice weekly [11] | Use human toothpaste |
| Choose a quiet, calm time | Force brushing when cat resists |
| Reward after brushing | Use dental floss [11] |
Between brushing sessions, I use these helpful additions:
- Dental sprays for daily plaque control
- Water additives for continuous care
- Specially formulated dental diets [11]
Pro Tip: Here’s my secret trick – I dab a bit of tuna water on my finger during training sessions. My cats love it, and it makes the whole experience much more pleasant [11].

When to Seek Veterinary Care
After years of caring for cats, I’ve learned to spot the difference between minor issues and real emergencies. Let me share when you should rush to the vet and when it’s okay to wait for a scheduled appointment.
Emergency warning signs

Final Thoughts – Cat Dental Care
Final Thoughts – Cat Teeth Grinding
Living with three cats has taught me that teeth grinding isn’t just another odd cat habit. My oldest cat Sophie first showed me how this behaviour could signal deeper health problems. When she started grinding her teeth last year, I quickly learned the importance of spotting these warning signs early.
I’ll never forget the relief on Sophie’s face after her dental treatment. That’s why I’m so passionate about proper dental care now. Yes, getting my cats used to tooth brushing was a challenge – Lucy still gives me the occasional grumpy face – but seeing them happy and pain-free makes it all worthwhile.
My regular vet visits with the cats have shown me just how crucial professional check-ups are. My vet spotted Max’s early gum disease during a routine cleaning, saving him from serious complications later. These check-ups, combined with our daily dental care routine at home, keep my cats’ teeth healthy.
Starting a dental care routine might seem daunting at first. Trust me, I’ve been there. But watching my cats suffer from dental pain was far worse than any struggle with toothbrushes. If you notice your cat grinding their teeth or acting differently, don’t wait – book that vet appointment. Your cat’s comfort and health are worth every effort.
FAQs
Q1. Why do cats grind their teeth?
Cats may grind their teeth due to dental issues, pain, or discomfort. This behaviour can indicate various health problems, including dental disease, injuries, or internal medical conditions, and often signals that veterinary attention is needed.
Q2. At what age do dental problems typically start in cats?
Dental issues can begin to develop in cats as early as four years old. Studies show that between 50% and 90% of cats over four years of age suffer from some form of dental disease, highlighting the importance of early and regular dental care.
Q3. How often should I brush my cat’s teeth?
Ideally, you should brush your cat’s teeth daily. However, if that’s not possible, aim for at least twice a week. Consistent dental care is crucial in preventing oral health issues and reducing the risk of teeth grinding.
Q4. What are the signs that my cat needs immediate dental care?
Look out for excessive drooling, difficulty eating, visible pain while eating, or blood in the saliva. These symptoms warrant urgent veterinary attention as they could indicate serious dental or health issues.
Q5. Can stress cause teeth grinding in cats?
Yes, stress and anxiety can contribute to teeth grinding in cats. Changes in environment, new pets, or alterations in daily routines can trigger this behaviour. However, it’s less common than dental issues as a cause of teeth grinding.
