If you hear a soft grinding or clicking sound when your cat eats, yawns, or even relaxes, your feline may be bruxing — the medical term for teeth grinding. Occasional grinding is harmless, but persistent cat bruxism is often a red flag for an underlying dental or medical problem. Because cats are masters at hiding pain, teeth grinding can be one of the few outward clues that something is wrong inside their mouth, jaw, or body. This guide explains the causes of cat teeth grinding, what the different patterns mean, and how to treat them with help from your veterinarian and gentle home care.
What Is Cat Bruxism?
Bruxism is the involuntary grinding, rubbing, or clenching of teeth. In cats it can appear as a rhythmic grinding of the molars, a repeated jaw movement, or clicking sounds while the cat is awake. Some cats grind because their teeth are misaligned or painful, while others grind as a response to stress or a deeper medical issue. According to the American Veterinary Medical Association (AVMA), any repetitive oral behavior that lasts more than a few days deserves a veterinary evaluation rather than a wait-and-see approach.
Common Causes of Cat Teeth Grinding
- Dental pain — the most common cause. Gum disease, tooth resorption (FORL), fractured teeth, or a dental abscess can all trigger grinding as the cat tries to relieve discomfort.
- Tooth misalignment — an improper bite or a crowded mouth, common in brachycephalic and small-jawed breeds, can cause teeth to rub together abnormally.
- Jaw or TMJ issues — temporomandibular joint problems or a recent jaw injury can lead to grinding.
- Oral foreign bodies — something stuck between the teeth or in the gums.
- Metabolic conditions — in some cats, grinding is linked to systemic issues such as kidney disease or hyperthyroidism.
- Stress and anxiety — some cats grind their teeth as a self-soothing behavior when stressed.
Is Cat Teeth Grinding Dangerous?
Left untreated, persistent bruxism can wear down tooth enamel, expose sensitive dentin, and even lead to fractures or root damage over time. More importantly, grinding is often a symptom of an underlying painful condition that will not resolve on its own. If tooth wear is severe, your cat may eventually need restorative or extraction treatment. Catching and treating the root cause early protects both your cat's teeth and their overall wellbeing.
How to Diagnose the Cause
Your veterinarian will start with a thorough oral exam — which often requires sedation for a complete look at the teeth and gums — followed by dental X-rays to detect problems below the gum line that cannot be seen with the naked eye. Depending on the suspected cause, bloodwork may be recommended to rule out metabolic conditions like kidney disease or thyroid problems. Based on these findings, your vet can design a targeted treatment plan.
Home Care That Supports Treatment
While your cat is being evaluated, gentle at-home oral care can ease discomfort and slow disease progression. RunyePet Dental Finger Wipes provide a soft, non-abrasive way to wipe away plaque and food debris from sore gums without the pressure of a brush. Adding RunyePet Dental Cleaning Powder to your cat's food helps reduce plaque at mealtime and supports healthier gums. For a complete toolkit, the RunyePet Dental Cleaning Kit gives you everything needed to keep the mouth clean through recovery.
Treatment Options for Teeth Grinding
- Treating the underlying dental disease — professional cleaning, extractions, or root therapy.
- Fixing misaligned teeth or managing jaw disorders with veterinary dental care.
- Addressing metabolic causes with medication and dietary changes prescribed by your vet.
- Reducing stress through environmental enrichment, routine, and calming aids.
- Using soft food temporarily if grinding is linked to painful chewing.
Frequently Asked Questions
Why is my cat grinding her teeth?
The most common reason is dental pain from gum disease, tooth resorption, or a fractured tooth. Stress and metabolic issues are other possible causes, so a veterinary exam is recommended.
Is teeth grinding in cats an emergency?
Not usually an emergency, but you should book a veterinary appointment soon. Persistent grinding signals an underlying problem that can worsen and become more painful over time.
Can I clean my cat's teeth if they grind?
Yes, but use a gentle approach. Soft dental finger wipes are less likely to aggravate sore gums than a toothbrush. If your cat is already in pain, ask your vet before starting home care.
Will my cat's teeth wear down from grinding?
Yes. Chronic bruxism can wear down enamel and damage teeth over time, which is why addressing the cause early is so important.
Final Thoughts
Cat teeth grinding is a clue, not a condition to ignore. By working with your vet to find the root cause and pairing treatment with gentle daily care from RunyePet Dental Finger Wipes and dental powder, you can protect your cat's teeth, relieve their discomfort, and keep that quiet purr healthy for years to come.
