Quick answer: Use a 30-tooth adult map for a cat older than about seven months. Use a 26-tooth kitten map before that. The four extra adult teeth are molars that baby mouths never carry.
A typical healthy adult cat has 30 permanent teeth: 12 incisors, 4 canines, 10 premolars, and 4 molars.
This page is a written cat-teeth diagram built from published anatomy counts. We did not anesthetize cats, take intraoral radiographs, or score plaque on a live panel.
Our research team used one selection rule. We mapped only the standard 26-tooth kitten set and the standard 30-tooth adult set. Extra teeth, retained baby teeth, and products that omit cats, a dose, or a mechanism stayed out.
The 16-and-14 Map
Count the mouth as two jaws, not one pile of points. The adult upper jaw holds 16 teeth. The adult lower jaw holds 14 teeth.
That split is the diagram most search pages skip. It is also the fastest way to find a missing tooth.
Start at the midline and work back on each side. Each half of the upper jaw has three incisors, one canine, three premolars, and one molar.
Each half of the lower jaw has three incisors, one canine, two premolars, and one molar. Add both sides and you reach 30.
The Merck Veterinary Manual states that most cats have 26 deciduous teeth and 30 permanent teeth. That pair of counts is the whole map in two numbers.
Name the four types as you look. Incisors sit in a short front row. Canines are the long fangs.
Premolars sit behind the canines. Molars sit at the back and appear only in the adult set.
The Journal of Feline Medicine and Surgery review by Reiter and Soltero-Rivera names the cutting pair. The maxillary fourth premolar and the mandibular first molar are the carnassial teeth.
Those two teeth do the shear. A cat that climbs a modern cat tree will often flash them when it bites sisal.
Kitten mouths use a 26-tooth map
Do not shrink the adult diagram and call it a kitten chart. The baby set is a different inventory.
Kittens have 12 incisors, 4 canines, and 10 premolars. They have no molars.
The Merck Veterinary Manual places deciduous incisors at 2 to 4 weeks of age. It places deciduous premolars at 5 to 6 weeks.
The same Merck page says permanent teeth usually begin to appear at around 4 to 7 months. That is the window where both maps can show at once.
Cornell University’s Feline Health Center puts milk teeth at about four weeks. The full baby set is present by about six weeks. Cornell also states that the baby teeth are gone by about six months.
The Reiter review in the Journal of Feline Medicine and Surgery tightens the bands. Deciduous teeth erupt between 2 and 6 weeks. Permanent teeth erupt between 3 and 6 months.
Retained baby teeth sit beside an adult twin. They are not a fifth tooth type. They are a leftover from the first set.
How clinic charts number the same 30 teeth
A drawing with labels is easier to reuse if each tooth has a number. Clinics use the modified Triadan system.
The first digit is the quadrant. Permanent right upper is 100. Permanent left upper is 200.
Permanent left lower is 300. Permanent right lower is 400.
The next two digits mark position from the midline. The central incisor is 01. The canine is always 04.
The first molar is always 09 when it is present. Cats skip some premolar numbers because evolution dropped those teeth.
The Reiter review shows this on a feline chart. The right upper canine is 104. The right upper fourth premolar is 108.
The left upper second premolar is 206. The left lower third and fourth premolars are 307 and 308.
The right lower first molar is 409. Those five numbers cover the teeth people most often miscount.
Deciduous quadrants use 500 through 800. A baby right upper canine is 504. Use those codes only on a kitten map.
Write 104 on a photo of the upper right fang. The diagram becomes searchable later.
Roots, sulcus depth, and what a drawing cannot show
A surface diagram stops at the gumline. Roots do not.
The Reiter review states that incisors and canines are single-rooted. Permanent mandibular third and fourth premolars and first molars have two roots.
Permanent maxillary fourth premolars have three roots. That is why a back-tooth extraction is not a simple pull.
Permanent maxillary second premolars and first molars often have two roots fused together.
The same paper sets a numeric healthy-sulcus limit. The space between tooth and free gingiva should not be deeper than 0.5 mm in cats.
That 0.5 mm figure is a probe depth, not a photo label. A diagram cannot prove it.
The review also places a nerve canal landmark. The infraorbital foramen sits about 1 cm dorsal to the maxillary third premolar.
That 1 cm offset matters for local blocks. It does not change how you count teeth at home.
Young adult teeth have a wider pulp cavity than older teeth. The Reiter radiographs compare a cat under 1 year with a cat over 3 years. Dentin thickens with age.
Keep spring-loaded gags out of home handling. The review warns that a wide-open mouth for a long time can reduce maxillary artery flow. The authors describe 20 mm and 30 mm plastic gags for clinic work only.
What published clinic series say about missing teeth
A 30-tooth map is a starting count, not a promise. Disease and injury remove teeth.
Cornell University’s Feline Health Center quotes dental specialist Daniel Carmichael on lifetime risk. Only about 10 percent of cats go through life without some dental problem.
The same Cornell page estimates periodontal disease in 85 percent of cats over the age of six. That is the most common reason an adult map comes up short.
Cornell also estimates feline odontoclastic resorptive lesions in 50 percent of cats. Those lesions start in dentin and can force extraction.
Feline gingivitis-stomatitis syndrome is rarer on that page. Cornell cites a rate of about one in 100 cats.
None of those percentages change the standard diagram. They explain why a living mouth may not match it.
Broken canines show up after falls and fights. Cornell lists trauma as a fracture cause and chewing as a less common one.
A harness walk is not a dental exam. It can still reveal a cat that mouths straps or refuses hard food after the outing.
Look at both mouths from the side before you introduce a rescue dog to a cat. A cracked canine changes how close play should start.
Signs Cornell lists include bad breath, red or swollen gums, pawing at the mouth, and refusal of hard food. Cats often hide pain.
A diagram helps you name the tooth you saw. It does not replace a clinic exam under anesthesia.
Home-care products that name cats and list a mechanism
A map tells you what to brush. It does not pick a paste.
Our research team compared published maker specs. We did not run a feeding trial or a plaque score.
The table below keeps four currently sold products. Each maker page names cats, lists a size or dose, and states a mechanism.
We excluded dog-only chews, human toothpaste, and any listing that hid the species.
| Product | Form | Maker-listed size or dose | Stated mechanism | Cat-use note from the maker page |
|---|---|---|---|---|
| Virbac C.E.T. Enzymatic Toothpaste | Paste or gel | 2.5 oz (70 g) tube | Dual-enzyme system; no foaming agents | Five flavors; poultry also in 12 g trial packets |
| Petsmile Professional Pet Toothpaste, Rotisserie Chicken, Small | Toothpaste | Pearl-size drop | Calprox (calcium peroxide) | Maker page says VOHC-accepted; use 1–2 times daily |
| FELINE GREENIES Adult Dental Treats | Crunchy treat | 8 treats twice daily for a 10 lb cat | Crunchy texture that the maker says helps clean teeth | Less than 2 calories per treat |
| Hill’s Science Diet Adult Oral Care Chicken & Brown Rice | Dry kibble | 3.5 lb and 7 lb bags | Interlocking fiber kibble | 326 kcal per cup; not for kittens or nursing cats |
Virbac’s US product page lists five flavors: poultry, malt, vanilla-mint, beef, and seafood. The same page states the 70 g tube size and says the pastes contain no foaming agents.
Petsmile’s product page tells you to use a pearl-size drop once or twice per day. It names Calprox as calcium peroxide and states the paste is VOHC-accepted.
GREENIES lists five treat flavors: catnip, oven roasted chicken, savory salmon, succulent shrimp, and tempting tuna. That page says a 10-pound cat can have eight treats twice a day.
Hill’s Pet Nutrition publishes 326 kcal per cup for the Oral Care chicken and brown rice recipe. The same page lists 33.7 percent dry-matter protein and 8.8 percent crude fiber. The food is not for kittens or for pregnant or nursing cats.
None of these products change the 30-tooth count. Human toothpaste stays off the table because pet pastes omit foaming agents meant for a sink-and-rinse routine.
How to use the map during daily handling
Lift one lip. Do not crank the jaw.
Count the three small incisors on that side first. Then find the canine.
Then count premolars behind the fang. Stop when you reach the last back tooth.
On an adult, that last upper tooth is the molar. On a kitten, the last tooth is still a premolar.
Write the count as upper 16 and lower 14, or as 26 for a baby. A single “about 30” note hides a missing carnassial.
If a tooth is pink, pitted, or sitting beside a twin, write the name down. You now have a number for the clinic. The map is a counting tool, not a treatment plan.
FAQ
How many teeth does an adult cat have?
A typical healthy adult has 30 permanent teeth. The Merck Veterinary Manual uses that count for most cats.
The set is 12 incisors, 4 canines, 10 premolars, and 4 molars. Injury and disease can lower the live total.
How many teeth does a kitten have?
A kitten’s full baby set is 26 teeth. Cornell’s Feline Health Center places that full set at about six weeks.
The baby inventory is 12 incisors, 4 canines, and 10 premolars. There are no deciduous molars.
Why does an adult map show 16 upper teeth and 14 lower teeth?
Each upper half has three premolars. Each lower half has only two.
Add the shared incisors, canines, and molars and the jaws are uneven. That 16-and-14 split is the adult diagram.
What is the Triadan number for the upper right canine?
It is 104 on the permanent chart. The Reiter review uses that number on its feline map.
The baby version of the same tooth is 504. Use 504 only on a kitten chart.
Can a healthy cat have fewer than 30 teeth?
Yes. Cornell cites Carmichael’s estimate that only about 10 percent of cats avoid dental problems for life.
Periodontal disease and tooth resorption remove teeth. The standard diagram still starts at 30.
Do cats have wisdom teeth?
No. Adult cats have one molar per quadrant, not a late third molar.
The four adult molars are the only extra teeth after the baby set. They are not a third-molar row.
When should I switch from the kitten map to the adult map?
Switch when the four molars are in and the baby teeth are gone. Cornell puts that swap near six months.
The Merck page gives a 4-to-7-month window for permanent eruption. If both sets are present, keep both maps in play.
