If you’ve noticed tiny, needle-sharp teeth on your floor or felt a little extra nip during playtime, you’re probably wondering: when do kittens lose baby teeth? It’s a milestone that every kitten owner goes through, and it’s totally normal. Just like human babies, kittens are born without teeth, develop a set of 26 deciduous (baby) teeth, and then shed them to make room for 30 permanent adult teeth. The whole process happens faster than you might think, and knowing what to expect can help you support your kitten through the sometimes uncomfortable teething stage.
The Kitten Teething Timeline: Week by Week
Your kitten’s baby teeth start coming in at around 2 to 4 weeks old. The incisors (the tiny front teeth) are first, followed by the canines (the long fangs) and premolars. By about 6 to 8 weeks, a healthy kitten should have a full set of 26 baby teeth. These little daggers are sharp for a reason: they help kittens transition from nursing to eating solid food. The real action begins around 3 months (12 weeks) when those baby roots start to dissolve and the adult teeth push up from below.
Between 3 and 4 months, you’ll likely find the first baby teeth on the floor or in your kitten’s bedding. The incisors go first, then the canines, and finally the premolars. By 5 to 6 months, most kittens have lost all their baby teeth. The last to come in are the molars, which don’t have baby predecessors. By 6 to 7 months, your kitten should have a full set of 30 adult teeth, including the four molars in the back. If you notice any baby teeth still hanging around after 7 months, or if adult teeth are coming in behind baby teeth (called retained deciduous teeth), it’s a good idea to check with your veterinarian.
Kittens have 26 baby teeth, but adult cats have 30. The extra four are the molars in the back of the mouth, which help with grinding food. That’s why you might notice your kitten suddenly showing more interest in crunchy kibble or chew toys around 5 to 6 months.
Signs Your Kitten Is Teething
Teething can be a little uncomfortable, and your kitten will let you know in a few common ways. The most obvious sign is increased chewing. Your kitten might start gnawing on furniture, shoes, electrical cords, or your fingers more than usual. You might also notice drooling, slightly red or swollen gums, a temporary decrease in appetite (especially for hard kibble), or a bit of irritability. Some kittens get a little clingy, while others want more space. It’s also normal to see a tiny bit of blood on a toy or in the water bowl, but if you see heavy bleeding, call your vet.
One thing that surprises many owners is that kittens often swallow their baby teeth while eating. Don’t worry, this is completely harmless. The teeth are tiny and will pass through the digestive system without any issue. If you do find a tooth on the floor, it’s a fun little souvenir, but you’re not missing anything if you never see one.
How to Help Your Teething Kitten
You can make the teething process much more comfortable for your kitten with a few simple strategies. First, provide safe things to chew on. Soft rubber kitten teething toys, chilled (not frozen) washcloths, or even a clean, damp dish towel twisted into a knot can feel amazing on sore gums. Avoid hard plastic or nylon toys that could damage emerging adult teeth. You can also offer wet food or softened kibble if your kitten seems reluctant to eat dry food. Just make sure any changes to diet are gradual to avoid an upset stomach.
Another helpful tip is to gently massage your kitten’s gums with a clean finger. This can provide relief and also gets your kitten used to having its mouth touched, which makes future teeth brushing and vet exams easier. Speaking of oral care, once the adult teeth are in (around 7 months), you can start introducing a toothbrush and cat-safe toothpaste. For now, focus on comfort and safety. If your kitten is chewing on cords or other hazards, redirect them to an appropriate toy. You might also consider using a calming collar if your kitten seems especially stressed or irritable during teething, as the gentle pheromones can help them relax.
“Teething is temporary, but the habits you build now, like gentle handling and safe chewing, will last a lifetime.”
When to See the Vet About Kitten Teeth
Most kittens sail through teething without any major issues, but there are a few red flags to watch for. If your kitten stops eating entirely for more than 24 hours, has extremely swollen or bleeding gums, develops bad breath (which can signal an infection), or seems to be in significant pain, make an appointment with your veterinarian. Retained baby teeth are another common issue. If an adult tooth comes in behind a baby tooth that hasn’t fallen out, the baby tooth needs to be extracted to prevent misalignment, plaque buildup, and gum disease. Your vet can check for this during a routine wellness visit around 6 to 7 months of age.
It’s also a good time to think about your kitten’s overall health and comfort. Teething can be stressful on the digestive system, so supporting gut health with a probiotic supplement can help keep things running smoothly. And if your kitten is chewing on everything in sight, including their food bowls, switching to elevated cat bowls can reduce neck strain and make mealtime more comfortable for sore mouths.
What to Expect After Teething Ends
Once your kitten has all 30 adult teeth, usually by 7 months, the teething phase is officially over. You’ll notice their bite feels different, much less sharp than those baby needles. Adult cat teeth are thicker and blunter, designed for tearing meat rather than the delicate nibbling of kittenhood. This is also the time to establish a regular dental care routine. Brushing your cat’s teeth a few times a week, providing dental treats, and scheduling annual vet dental checkups can prevent problems like periodontal disease down the road.
Your kitten’s new adult teeth will also change their eating habits. They may become more efficient at crunching kibble and might show more interest in raw or chewy treats. Keep an eye on their weight and adjust portions as needed. And if you plan to harness train your cat for outdoor adventures, now is a great time to start, since they’re past the fragile teething stage and more receptive to training.

Remember, every kitten is a little different. Some lose teeth right on schedule, others are early or late by a few weeks. As long as your kitten is eating, playing, and acting normally, there’s usually nothing to worry about. If you have any concerns, your veterinarian is always the best source of advice for your individual kitten.
