If you’ve ever peered into your cat’s yawning mouth and wondered exactly what’s in there — you’re not alone. How many teeth do cats have is one of the most searched feline health questions, and the answer matters more than most pet owners realize. A cat’s teeth are precision instruments shaped by millions of years of evolution. Understanding them helps you spot problems early, time veterinary visits correctly, and give your cat a longer, more comfortable life.
How Many Teeth Do Cats Have? The Exact Numbers
Adult cats have exactly 30 permanent teeth. That number breaks down into 12 incisors, 4 canines, 10 premolars, and 4 molars — 14 on the upper jaw and 16 on the lower. Kittens arrive toothless but develop 26 deciduous (baby) teeth by around 6–8 weeks of age. These include 12 incisors, 4 canines, and 10 premolars; kittens do not have molars until their permanent set emerges.
Types of Cat Teeth & Their Functions
Each tooth type in a cat’s mouth has a specific mechanical role. Cats are obligate carnivores, so their dentition evolved entirely for gripping, puncturing, and shearing meat — not grinding like human molars do.
| Tooth Type | Count (Adult) | Location | Primary Function | Kitten Has? |
|---|---|---|---|---|
| Incisors | 12 (6 upper, 6 lower) | Front of mouth | Nibbling, grooming, small bites | ✅ Yes (12) |
| Canines | 4 (2 upper, 2 lower) | Beside incisors | Gripping prey, puncturing, carrying | ✅ Yes (4) |
| Premolars | 10 (6 upper, 4 lower) | Behind canines | Shearing food into chunks | ✅ Yes (10) |
| Molars | 4 (2 upper, 2 lower) | Rear of mouth | Crushing dry food & hard material | ❌ No |
The large upper premolar and lower molar together form what veterinary dentists call the carnassial pair — a scissor-like shearing mechanism unique to carnivores. This is why cats never grind food side-to-side; their jaws move up and down only.
Cat Teeth Development: From Birth to 7 Months
Understanding when cat teeth grow helps owners recognize normal teething behavior and catch problems like retained baby teeth before they cause damage.
Kittens are born with no visible teeth. Baby teeth sit just below the gumline, developing in the jaw.
Baby incisors appear first (2–3 weeks), followed by canines and premolars. By 6–8 weeks, all 26 deciduous teeth are present.
Baby teeth begin loosening. Kittens chew more, may appear irritable, and gums can look slightly pink. Adult incisors start erupting.
All 26 baby teeth fall out and adult counterparts emerge. Canines and premolars replace their deciduous versions. Adult molars (new additions) begin erupting.
The full adult set of 30 permanent teeth is in place. All teeth should be present; retained baby teeth at this stage require veterinary evaluation.
Most owners never find kitten teeth because cats frequently swallow them while eating — this is completely normal. If you do spot a tiny, translucent tooth on the floor, it’s a sign your kitten’s development is right on track. For more on kitten development milestones, see our Health & Wellness guides.
Kitten Teeth vs. Adult Cat Teeth: Side-by-Side
Cat Dental Disease: What the Research Shows
The data is striking. Research published in Frontiers in Veterinary Science confirms that over 70% of cats show some form of dental pathology. A large UK primary-care study found periodontal disease carries a 1-year period prevalence of 15.2%, making it the single most common specific diagnosis in cats. Tooth resorption — a painful condition where the body breaks down its own teeth — affects 29–67% of adult cats in various studies.

Breeds at Higher Periodontal Risk
Not all cats face equal dental risk. Breed genetics, jaw shape, and tooth spacing all influence how quickly plaque and tartar form. VetCompass data from the UK identified these breeds with the highest annual prevalence of periodontal disease:
Narrow jaw creates tighter tooth spacing, accelerating tartar buildup between molars and premolars.
Large body size and age-related factors put Maine Coons above average. Senior cats need bi-annual dental checks.
Rounder skull shape can crowd back teeth. Monthly home checks and annual professional cleaning are advised. Read our full breed health guide for related care tips.

Common Dental Conditions That Affect Cat Teeth
Because cats instinctively hide pain, dental disease often goes undetected until it’s advanced. Knowing the conditions that affect how many teeth cats have over time helps owners act before permanent damage occurs.
| Condition | What Happens | Prevalence | Key Sign |
|---|---|---|---|
| Periodontal Disease | Bacterial infection destroys gum and bone around tooth roots | Most common diagnosis in cats (UK data) | Bad breath, red gums |
| Tooth Resorption (TR) | Body reabsorbs its own tooth structure — deeply painful | 29–67% of adult cats | Holes in teeth, drooling |
| Gingivitis | Inflammation of gum tissue; early and reversible stage | ~13% (US veterinary survey) | Swollen, bleeding gums |
| FCGS (Stomatitis) | Severe whole-mouth inflammation, often immune-mediated | Less common but debilitating | Inability to eat, weight loss |
| Retained Deciduous Teeth | Baby teeth fail to fall out, crowding adult teeth | Occasional in kittens 5–7 months | Double tooth appearance |
| Dental Calculus (Tartar) | Mineralized plaque coats tooth surface | 24% of cats (Banfield 2014 data) | Yellow-brown crust on teeth |
Warning Signs Your Cat Has Dental Problems
Cats routinely mask oral pain. These are the signals veterinary professionals advise watching for closely — especially in cats over 3 years old, when dental issues become far more common.
Persistent foul odor (beyond normal “meat breath”) signals bacterial infection or tartar buildup.
Cats with tooth pain pick up food and drop it repeatedly. Watch for eating on one side only.
Unusual drooling — especially with blood-tinged saliva — suggests significant oral pain.
A cat repeatedly touching their face signals acute oral discomfort. Seek prompt veterinary care.
Sudden irritability, hiding, or aggression can be pain responses linked to dental disease.
Reluctance to eat due to oral pain leads to rapid weight loss, especially in senior cats. If your cat’s breathing seems labored too, read our guide on heavy breathing in cats.
How to Care for Your Cat’s Teeth at Home
The American Animal Hospital Association recommends daily tooth brushing as the gold standard. In practice, brushing 3–4 times per week makes a significant difference. Start slowly — touch your cat’s lips daily before ever introducing a brush.
Use a soft-bristled cat toothbrush and enzymatic cat-safe toothpaste. Never use human toothpaste — fluoride is toxic to cats.
Look for VOHC (Veterinary Oral Health Council) approved treats. They mechanically reduce plaque during chewing.
VOHC-approved water additives reduce oral bacteria between brushing sessions without requiring direct contact.
Annual professional dental cleaning under anesthesia allows thorough scaling, polishing, and full-mouth X-rays. Essential after age 3.
How Many Teeth Do Cats Have vs. Dogs?
A common point of confusion: dogs actually have more teeth than cats. An adult dog carries 42 permanent teeth — 12 more than a cat’s 30. The reason cats have fewer is anatomical. Their shorter, narrower jaws evolved for bite strength and precision rather than grinding, meaning they need fewer, more specialized teeth. Fewer teeth also means tighter spacing, which accelerates plaque accumulation — one reason cats develop dental disease at higher rates than dogs despite having fewer teeth total.
Signs Your Kitten Is Teething
Teething typically runs from 3 to 6 months. Many owners mistake teething behavior for aggression or illness. Recognizing what’s normal helps you support your kitten without unnecessary alarm.
| Sign | Normal? | What to Do |
|---|---|---|
| Increased chewing on objects | ✅ Normal | Provide soft rubber chew toys; remove fragile items |
| Slight gum redness | ✅ Normal | Monitor; offer cool chew toys for soothing |
| Specks of blood in water bowl | ✅ Usually normal | Watch quantity — excessive bleeding warrants a vet call |
| Reduced appetite for 1–2 days | ✅ Can be normal | Switch to wet food temporarily to ease discomfort |
| Baby tooth still present at 6 months | ❌ Retained tooth | Book a vet appointment — likely requires extraction |
| Refusal to eat for over 2 days | ❌ Needs attention | Contact vet immediately; may indicate infection or misalignment |
If you suspect your cat has a health concern beyond teething, reviewing their age in human terms can help frame the timeline. Our Cat Age Calculator converts cat years to human years so you can better understand your cat’s life stage.
