Cats aren't always obvious when something hurts, especially when the problem is hiding inside their mouth. That's why knowing the signs of dental problems in cats is so helpful. A change in breath, eating habits, or even how your cat reacts when you touch their face may be telling you something feels different.
Common signs of dental problems in cats include bad breath, red or bleeding gums, drooling, eating differently, pawing at the mouth, broken or discolored teeth, and changes in behavior. If you notice any of these, schedule a veterinary exam.
Dental problems are far from unusual. Cornell University's Feline Health Center reports that between 50% and 90% of cats over four years old have some form of dental disease. The goal isn't to diagnose your cat at home. It's to know their normal well enough to recognize when it's time for a checkup.
Why Cat Dental Problems Are Easy to Miss
A cat with dental discomfort may not suddenly stop eating or cry out in pain. Some cats with dental disease show few outward signs at all. Veterinary examination, and in some cases dental X-rays under anesthesia, may be needed to uncover problems that aren't visible above the gumline.
That makes the little changes important. You know your cat better than anyone, so pay attention when something about their eating, grooming, breath, or behavior starts to feel different.
7 Signs of Dental Problems in Cats
One sign by itself doesn't tell you exactly what's wrong. What matters is noticing when something is new, persistent, or unusual for your cat.
1. Bad breath that's stronger than usual
Persistent bad breath can accompany dental disease and shouldn't automatically be dismissed as normal "cat breath."
2. Red, swollen, or bleeding gums
Healthy gums shouldn't look very inflamed or bleed routinely. Gingivitis can cause redness, swelling, discomfort, and sometimes bleeding along the gumline.
3. Drooling more than usual
Excessive drooling, or saliva containing blood, can occur when a cat has oral discomfort.
4. Eating differently
Watch for taking longer to eat, dropping food, turning the head while chewing, chewing on one side, preferring softer foods, or seeming hesitant at mealtimes. These can all be signs of cat tooth pain.
5. Pawing at the mouth or face
Repeated pawing, head shaking, or jaw chattering can be associated with oral discomfort.
6. Visible changes to the teeth
Broken, loose, discolored, or heavily tartar-covered teeth deserve veterinary attention.
7. Changes in behavior
A cat dealing with dental discomfort may become more irritable, less interested in food, or suddenly resist having their face or mouth touched.
"But My Cat Is Still Eating…"
This is one of the biggest reasons cat teeth problems get missed. Eating doesn't necessarily mean your cat's mouth feels fine. Some cats keep eating despite dental pain, while others change how they eat in small ways: chewing on one side, slowing down, dropping pieces, or choosing softer food.
So instead of only asking, "Is my cat eating?" ask, "Is my cat eating normally?" That small distinction can tell you much more.
Common Dental Problems in Cats
The signs above can point to several different conditions. Only a veterinarian can tell which one your cat has, but it helps to know the names you might hear:
- Gingivitis: inflammation of the gums, often an early stage of dental disease.
- Periodontal disease: damage to the tissues that support the teeth, which can progress if plaque and tartar build up.
- Tooth resorption: a common feline condition in which a tooth gradually breaks down. It can be painful and is often hidden below the gumline, which is one reason X-rays matter.
- Stomatitis: severe, painful inflammation of the mouth and gums.
How to Check Your Cat's Mouth at Home
A quick, gentle look every so often helps you learn what's normal. Only try this when your cat is calm.
- Choose a quiet moment, and let your cat sniff and relax first.
- Gently lift the upper lip on one side with a clean finger.
- Look at the gumline. Healthy gums are generally a pale to healthy pink.
- Note any redness, swelling, bleeding, or heavy tartar.
- Look for broken, loose, or discolored teeth.
- Stop right away if your cat pulls away, resists, or seems to be in pain, and reward them for the effort.
This is a check-in, not a diagnosis. Your vet can see what you can't, including what's below the gumline.
When to Call Your Veterinarian
Book a vet visit if you notice any of the seven signs above, especially if they last more than a few days or keep returning. Contact your vet promptly if your cat:
- Stops eating or is eating much less
- Has facial swelling
- Has heavy bleeding from the mouth
- Shows obvious pain, such as crying out, hiding, or refusing to be touched around the face
A cat that won't eat can become seriously unwell, so don't wait it out.
How to Support Your Cat's Dental Health at Home
Regular veterinary dental checks and consistent home care work together to support cat oral health. The American Veterinary Medical Association recommends having a pet's teeth and gums checked by a veterinarian at least once a year, with earlier evaluation when concerning signs appear.
At home, that can mean becoming familiar with your cat's mouth and gradually building a toothbrushing routine once your vet confirms their mouth is healthy enough for brushing. It doesn't have to start with a perfect session: let your cat investigate the cat toothbrush, lift their lip briefly, brush a few teeth, reward them, and stop. Then build from there.
If your cat has bleeding gums, significant inflammation, or sudden pain around the mouth, have your vet examine them before brushing. A toothbrush helps maintain a healthy mouth. It isn't a treatment for a painful dental problem. And if your cat used to tolerate brushing and suddenly doesn't, that change is worth investigating rather than assuming they just decided to hate their toothbrush.
FAQ: Dental Problems in Cats
Is bad breath normal in cats? A little odor can be normal, but persistent or strong bad breath can be a sign of dental disease. If it's new or getting worse, mention it to your vet.
How do I know if my cat's tooth hurts? Cats often hide pain. Look for eating differently, dropping food, pawing at the mouth, drooling, pulling away when their face is touched, or behavior changes. Only a vet can confirm the cause.
Can cat dental problems go away on their own? Dental disease generally doesn't resolve without treatment, and it can progress. If you suspect a problem, a veterinary exam is the safest next step.
How can I check my cat's teeth at home? When your cat is calm, gently lift their lip and look at the gumline and teeth for redness, swelling, bleeding, tartar, or broken teeth. Stop if they resist.
How often should a cat see the vet for dental checks? The AVMA recommends at least a yearly check of your pet's teeth and gums, sooner if you notice any concerning signs.
Know Their Normal
You don't need to become an expert in feline dentistry. You just need to become an expert in your cat. Know how they normally eat. Know what their breath is usually like. Notice when they become sensitive around their face. And take a peek at those tiny teeth every once in a while.
Because when it comes to cat dental health, noticing that something has changed is often the first step toward getting your cat the care they need.
