Do Cats Lose Their Teeth After a Year Old?

Kittens are born completely toothless.

Kittens are born completely toothless.

Although it may not always occur to cat owners, young kittens, just like human children, lose their teeth at a certain tender age. When your wee fluff ball is several months old, her baby teeth will start to fall out in order to pave the way for her adult chompers.


When a kitten is born, she doesn't have any teeth at all, just like human newborns. However, the tiny pearly whites slowly but surely begin to emerge during approximately the second week of the kitty's young life. In some cases, the deciduous teeth start appearing slightly later on, at around 4 weeks. According to the Humane Society Veterinary Medical Association, when a kitten hits roughly 8 weeks old, she should possess her full set of baby teeth -- 26 in total.

Baby Teeth Loss

Young cats do not begin to lose their teeth after a year old. In fact, the process happens significantly quicker than that. The ASPCA states that kittens typically begin to lose their deciduous teeth at a mere 3 months of age or so.

Permanent Teeth

Once a kitty begins losing her baby teeth at around 3 months old, her permanent teeth will start growing in seemingly like clockwork. As soon as a cat starts losing teeth she begins getting in replacements. The process starts with the incisors, then moves onto the premolars, molars and canines. In general, most felines acquire all 30 of their adult teeth by the time they reach the sixth month mark, well before one year of age.

Aging Cats

If your cat is well past the kitten years, he may lose his teeth due to simple aging, especially if he's a sweet senior that is at least 10 years old. If you notice your sprightly and young cat experiencing tooth loss, however, seek immediate veterinary attention, as it could be a sign of a serious dental issue. On the other hand, elderly cats often experience dental difficulties, from icky tartar accumulation to the gum inflammation disorder gingivitis. Keep your precious pet's teeth healthy and 100 percent intact by taking her in for routine veterinary visits, especially as she gets older.
