Tooth Changes in Cats

Kittens do have a deciduous (baby) set of teeth that are gradually shed during their growing phase. Knowing whether this particular tooth is loose due to normal turnover, or is broken would require further assessment. Because this cat is semi-feral, damage (fracture etc.) could conceivably occur to the tooth while roaming around outside.

It is uncommon for owners to notice the teeth changing over since the process is gradual, and the teeth are small. Sometimes, a shed tooth can be found on a rug or floor, but unless the owner brushes the teeth daily, it is easy to miss the transition.

Sometimes you will see a loose tooth sitting overtop the new permanent tooth as it pushes up from underneath which can make it look "broken" if the baby tooth is dangling from the gum. If the immature teeth are not shed, this can cause displacement of the permanent teeth. This situation is more common in dogs, but in cats, is seen particularly in short-nosed breeds like the Persian.

Cats have a standard number of adult or permanent teeth: 30

We usually write these as a DENTAL FORMULA:

Baby: 3i 1c 3p
3i 1c 3p

Adult: 3I 1C 3P 1M
3I 1C 3P 0M

(Lower case letters are for the baby teeth, and upper case letters are for the adult teeth)

6 incisors (i or I) across the front, 6 top and 6 bottom =12

2 canine teeth ("fangs" or c, C) on each side, top and bottom =4

3 premolars (p, P) top and bottom on each side =12

1 molar (M) on the top at the back =2

The teeth usually finish turn over by 6 1/2 to 7 months of age. Incisors usually turn over between 2 1/2 and 4 months of age. Premolars usually change between 3 and 5 months. At about 5 to 6 months of age, the canines change over. Molars come in around 5 months of age—there are no baby molars. These shedding and adult eruption times are very approximate.

At 3 months, this kitten is ready for a second vaccination booster and stool check. Your veterinarian can check this tooth during the examination. Catching a semi-feral cat can be a challenge, but if you are handling the cat on a regular basis, it is important to make sure the cat that adopted you does not transmit disease to you or your indoor pets (if you have any). Rabies and intestinal parasite protection are particularly important for this type of situation.

The adult teeth of the cat must last the remainder of the lifespan following maturity, so proper dental care is essential to protect them against caries (cavities) and periodontal disease. Your veterinarian can advise you regarding a home dental care program to keep them white and healthy through the years.
