Dental health is one of the most overlooked aspects of cat care, and one of the most impactful. Studies suggest that by age three, more than 70% of cats show signs of dental disease. Left untreated, problems with your cat’s teeth cause chronic pain, interfere with eating, and can seed serious infections elsewhere in the body. Understanding how the teeth develop, what can go wrong, and how to keep them clean is essential for any responsible owner.
Cat Dental Anatomy
Adult cats have 30 teeth. Kittens have 26 deciduous (baby) teeth that are replaced between three and six months of age. The adult set breaks down as follows:
- 12 incisors (6 upper, 6 lower) — the small front teeth used for nibbling and grooming
- 4 canines (2 upper, 2 lower) — the long, pointed teeth used for gripping and killing prey
- 10 premolars (6 upper, 4 lower) — used for shearing food
- 4 molars (2 upper, 2 lower) — used for crushing
Unlike human teeth, a cat’s teeth are built for cutting and tearing rather than grinding. Cats don’t chew their food the way we do; they use their carnassial teeth, the large premolars, to shear meat into swallowable pieces. This is why cats bolt their food. It isn’t greed, it’s anatomy.
How Many Teeth Does a Cat Have?
The short answer most owners are searching for: an adult cat has 30 permanent teeth, while a kitten has 26 baby teeth. If you ever count fewer than 30 in an adult, that is worth a vet visit, because a missing tooth usually means one has been lost to disease or trauma rather than never having erupted.
Kitten Teething
Kittens are born without visible teeth. The typical timeline runs:
- 2–3 weeks: incisors begin to emerge
- 3–4 weeks: canines appear
- 4–6 weeks: premolars come through (there are no deciduous molars)
- 3–4 months: baby teeth begin to fall out
- 6 months: the full adult set is usually in place
During teething, kittens chew more aggressively. This is normal and should be redirected to appropriate items rather than fingers or furniture. Offering a range of safe cat toys early on gives them something acceptable to gnaw and helps curb the kind of mouthing that can develop into a habit of biting later. Some kittens show mild irritability, drooling, or reluctance to eat hard food. If you notice bleeding gums, a retained baby tooth sitting alongside an erupting adult tooth, or persistent refusal to eat, consult your vet.
Common Cat Dental Problems
Periodontal Disease
The most common dental condition in cats. It begins with plaque, which hardens into tartar, leading to gingivitis (inflamed gums) and eventually periodontitis, the destruction of the tissue and bone supporting the teeth. Signs include red gums, bad breath, drooling, and reluctance to eat hard food.
Tooth Resorption (FORLs)
Feline odontoclastic resorptive lesions affect roughly 30–60% of adult cats. The body’s own cells attack the tooth structure, creating painful cavities at or below the gum line. The cause is still unknown, and affected teeth usually need extraction, as there is no reliable way to reverse resorption.
Stomatitis
Severe, painful inflammation of the mouth lining. Cats with stomatitis may drool heavily, paw at their mouths, refuse food, or cry when eating. It is thought to be immune-mediated. Treatment ranges from anti-inflammatory medication to full-mouth extraction in severe cases, which sounds drastic but often brings dramatic relief.
Broken Teeth
Canine teeth are the most commonly fractured, usually through trauma such as a fall or a fight. A broken tooth exposes sensitive inner tissue and can become infected, so it should always be assessed by a vet.
How to Clean Your Cat’s Teeth
Prevention is far cheaper and kinder than treatment. The gold standard is regular brushing with a pet-specific enzymatic toothpaste, never human toothpaste, which contains ingredients that are toxic to cats.
- Start slowly. Let your cat lick a little of the toothpaste off your finger for a few days so the taste becomes a positive thing.
- Progress to rubbing a finger or a soft pet toothbrush along the outer surfaces of the teeth, where tartar builds up most.
- Aim for a short daily session rather than a long weekly battle. Calm consistency beats force every time, the same principle that underpins all cat training.
Dental diets, water additives, and vet-approved dental treats can supplement brushing, but none fully replace it. Annual veterinary dental checks, with a professional scale and polish under anaesthetic when needed, remain the backbone of good feline oral care.

The Bottom Line
Your cat’s teeth are easy to ignore right up until they cause a painful, expensive problem. Learn what a healthy mouth looks like, start a gentle brushing routine early, and never dismiss bad breath as merely unpleasant, because it is often the first warning sign of disease. A few minutes of care each week can spare your cat years of avoidable pain.
