Adult cats usually have 30 permanent teeth. Kittens have 26 baby teeth, also called deciduous teeth, before their adult teeth come in.
That is the quick answer. But if you are looking inside your cat’s mouth because you noticed a tiny tooth on the floor, a missing tooth, bad breath, red gums, or your kitten chewing everything in reach, the number alone may not be enough.
I tend to look at this question in two ways. First, there is the normal tooth count by age. Second, there is what that tooth count can tell you about your cat’s health. A cat with fewer than 30 visible teeth may be doing well after veterinary dental extractions, but a suddenly missing, loose, painful, or broken tooth is not something I would ignore.
How Many Teeth Do Adult Cats Have?
Most adult cats have 30 permanent teeth.
Those teeth are divided into different types:
| Type of tooth | Number in adult cats | Main job |
|---|---|---|
| Incisors | 12 | Small front teeth used for nibbling and grooming |
| Canines | 4 | Long, pointed teeth used for gripping and puncturing |
| Premolars | 10 | Back teeth used for cutting and shearing food |
| Molars | 4 | Rear teeth used for chewing and crushing |
Cats do not have the same broad chewing teeth that humans do. Their mouths are built more for gripping, tearing, and shearing than for grinding food into a paste.
That is one reason a cat’s mouth can look a little surprising when you inspect it. The tiny front incisors are easy to miss, the canines are obvious, and the back teeth can be hard to see unless your cat is relaxed and cooperative. Many owners never get a clear view of all 30 teeth at home.
For me, the safer approach is not to force a full tooth count. It is more useful to notice changes: bad breath, red gums, tartar, missing teeth, loose teeth, drooling, chewing on one side, dropping food, or signs that your cat is uncomfortable around the mouth.
How Many Teeth Do Kittens Have?
Kittens have 26 baby teeth.
They are not born with visible teeth. Their baby teeth usually begin to come in when they are a few weeks old, and the full baby set is typically present by around 6 to 8 weeks.
This is why teeth can help estimate a young kitten’s age, especially with rescued kittens. A very young kitten with no visible teeth is in a different stage from a kitten with small baby teeth already showing. Still, tooth eruption is only an estimate. Kittens develop at slightly different speeds, and a veterinarian can give a more reliable age estimate by looking at the whole kitten, not just the mouth.
Kitten baby teeth are temporary. They are meant to fall out and be replaced by permanent adult teeth. If you find a tiny tooth on a blanket or near the food bowl, it may simply be part of normal teething. Many owners never find any baby teeth at all because kittens often swallow them while eating.
When Do Cats Get Their Adult Teeth?
Cats usually start getting permanent teeth around 4 months of age, and most have their full set of 30 adult teeth by about 6 to 7 months.
This stage can look messy because the mouth is changing quickly. A kitten may have some baby teeth, some adult teeth, and some gaps where teeth are shifting. That does not mean anything is wrong by itself.
Mild teething discomfort can happen. Some kittens chew more, drool a little, seem irritable, or act briefly hesitant with food because the gums feel tender. This is different from a kitten that refuses food, bleeds heavily, has facial swelling, seems very painful, or has a tooth that looks broken or badly out of place.
One useful thing to watch for is a “double tooth” look, where a baby tooth and adult tooth appear to be occupying the same area. That can happen when a baby tooth does not fall out as it should.
What If a Kitten Has Baby Teeth That Do Not Fall Out?
A baby tooth that stays in place after the adult tooth has erupted is called a retained deciduous tooth.
This is not just a cosmetic issue. If a baby tooth remains where the adult tooth needs space, it can push the adult tooth into an abnormal position. That crowding can trap food and debris, contribute to tartar and gum inflammation, and create bite problems.
The most practical sign for owners is seeing two teeth where you expected one. The canine teeth are often the easiest place to notice this because they are large and visible.
This is where I would stop guessing and call a vet. A retained baby tooth is easier to address before it creates bigger dental problems. It is also not something to pull at home. Cat teeth are small, the roots can be delicate, and the mouth is painful when something is wrong.
Is It Normal for Adult Cats to Have Fewer Than 30 Teeth?
Some adult cats have fewer than 30 teeth, but that does not automatically mean the cat is unhealthy.
A cat may have fewer visible teeth because of previous veterinary extractions, trauma, congenital missing teeth, abnormal development, periodontal disease, or tooth resorption. Some cats also have unusual dental anatomy, such as extra teeth, missing teeth, or tooth root variations.
The context matters.
If your cat had diseased teeth removed by a veterinarian and is now eating comfortably, fewer teeth may simply be part of that cat’s dental history. Many cats do well after extractions, especially when painful teeth have been removed.
But if a tooth is suddenly missing, loose, broken, discolored, bleeding, or painful, that is different. I would not treat that as “just aging.” Adult cats do not simply need to lose teeth as a normal life stage. Tooth loss often points to dental disease, injury, or another problem that deserves a veterinary exam.
Cat Teeth and Dental Disease
The tooth count is simple. The dental health behind it is where owners can get misled.
Dental disease is common in cats, especially as they get older. The veterinary sources used for this article report that many cats over age three or four have some form of dental disease. The most common problems include gingivitis, periodontitis, and tooth resorption.
Gingivitis means gum inflammation. The gums may look red, swollen, or sore. This early stage can be linked to plaque, which is a sticky bacterial film that builds on teeth.
If the problem progresses, it can become periodontitis. That means the deeper structures supporting the tooth are damaged. Once support structures are lost, the damage is more serious and not just a matter of brushing the surface of the tooth.
This is why bad breath and tartar should not be dismissed as normal “cat mouth.” Brown tartar may be what you see, but the bigger concern is often inflammation and bacteria around or below the gumline.
Tooth Resorption Is Easy to Miss
Tooth resorption is one of the most important feline dental problems to understand.
In tooth resorption, the tooth structure gradually breaks down. It can affect the crown, root, or both. When sensitive inner parts of the tooth are exposed, it can be very painful.
What makes this tricky is that cats may not show pain clearly. A cat with a painful tooth may still eat. Some cats swallow kibble whole, chew on one side, drop food, prefer softer food, tilt the head while eating, drool, or chatter the jaw. Others may look normal until the disease is advanced.
This is why I would be cautious about saying, “My cat eats fine, so the teeth must be fine.” Eating is reassuring, but it does not rule out dental pain.
Tooth resorption often requires dental X-rays to detect properly, because much of the tooth structure is below the gumline. If a cat has a tooth that looks broken, has gum growing over it, or seems painful near the gumline, a vet exam is the safer choice.
Signs Your Cat’s Teeth May Need Veterinary Attention
Some changes are worth monitoring. Others should push you toward a veterinary appointment.
Possible dental warning signs include:
