Do Kittens Lose Their Teeth? Kitten Teething Timeline and Signs

Do kittens lose their teeth? Yes. Every kitten sheds all 26 of its baby teeth, usually starting at around 3 to 4 months of age, as 30 permanent adult teeth grow in to replace them. By about 6 to 7 months, the swap is complete.

So if you just found a tiny tooth on the rug, or your kitten has started gnawing on everything in reach, teething is the most likely reason. Here is the week-by-week timeline, the normal signs, what actually helps, and the few situations where a lost or stuck tooth means a trip to the vet.

When Do Kittens Lose Their Baby Teeth?

Kittens start losing their baby teeth at around 3 months of age, and most have a full set of adult teeth by 6 to 7 months, according to VCA Animal Hospitals. The first adult teeth to arrive are the tiny middle incisors at the front, at about 12 weeks.

From there, the replacement works backward through the mouth. The second and third incisors follow at around 14 and 16 weeks, per the ASPCA's shelter guidance, and the canines (fangs) and premolars change over between about 4 and 6 months. The four adult molars have no baby version, so they simply erupt on their own.

Why do cats lose their baby teeth at all? Like human baby teeth, kitten teeth are temporary. The Merck Veterinary Manual describes them as built for a small mouth and a short working life. As each adult tooth grows in underneath, the baby tooth's root dissolves, the crown loosens, and it drops out.

The difference from people is speed: cats get just two sets of teeth, and kittens swap one for the other in a few months, with teething over and adult teeth done growing in by about 7 months. Expect the most chewing in that stretch, so have a few soft fabric or rubber toys ready before the first tooth wobbles.

Kitten Teething Symptoms

Most kittens show only mild signs of teething, and many owners notice nothing more than extra chewing. Common kitten teething symptoms include:

• Chewing and biting more than usual, especially on soft objects, hands and cords
• Red or slightly swollen gums along the tooth line
• Mild bad breath
• A little extra drooling
• Tiny spots of blood on toys or in food as a tooth comes out
• Eating more slowly, dropping kibble, or preferring soft food for a day or two
• Pawing at the face or acting a little crankier than usual
• Finding a tiny tooth on the floor, bedding or a toy

These signs should be mild and short-lived, and a teething kitten still plays, eats and sleeps normally. Grinding teeth is not a typical teething sign at any age. Cats Protection lists it as a reason to contact your vet, along with bleeding gums, struggling to eat, growling at food, drooling, pawing at the mouth and regularly dropping food. A trace of drool or a brief paw at the face is common, but if any of these signs is more than slight or lasts beyond a day or two, call your vet.

How to Tell If Your Kitten Is Teething

Behavior gives you the first hint, but a quick look inside the mouth tells you for sure. Pick a calm moment, gently lift your kitten's lip at the side, and look for:

• A gap where a baby tooth has already fallen out
• A loose, wobbly baby tooth, or the tip of a new adult tooth pushing up behind it
• A thin red line along the gum where a tooth is coming through
• Front teeth of two different sizes, since adult incisors are wider than the pointed baby ones

If your kitten is between about 3 and 7 months old and you spot any of these, teething is the likely explanation. A loose tooth is normal at this age. Two teeth crowded into one spot is not, and it needs a vet check.

How to Help a Teething Kitten

You cannot speed teething up, but you can make it more comfortable and steer all that chewing somewhere safe. Most of it comes down to the right kitten teething toys, a little household protection, and patience. For safe picks at each stage, see our guide to kitten toys by age.

• Offer soft teething toys made of fabric, plush or soft rubber, and rotate them so they stay interesting
• Skip hard plastic and wooden chews, which Cats Protection warns can damage fragile baby teeth
• Kittens do not need special teething rings; any soft, kitten-sized chew toy does the same job
• Supervise chew time and throw away toys once they start to shred
• Protect electrical cords by hiding them behind furniture or applying a bite deterrent spray, as the ASPCA suggests

Does It Hurt When a Kitten Loses a Tooth?

It can be uncomfortable. Some veterinary sources describe teething as painful, while Cats Protection says kittens should only feel mild discomfort. In practice, most kittens show teething pain through extra chewing, a little fussiness and slower eating rather than obvious distress.

The tooth itself usually comes out easily, because its root has already been dissolving, and a drop or two of blood is normal. Signs that it hurts more than it should, such as refusing food, struggling to eat or constantly pawing at the mouth, are not typical teething and need a vet.

Never give a kitten human pain relievers or baby teething gels. VCA warns that acetaminophen is toxic to cats, and the Pet Poison Helpline notes that many teething gels contain benzocaine, which can harm pets. Cold, soft toys and softened food are the safe comfort measures.

Why Teething Kittens Bite and Chew More

Teething adds a strong urge to chew on top of normal kitten play, so biting often ramps up during the teething months, when sore gums make everything feel worth gnawing.

So at what age are kittens the naughtiest? No study names a single age, but two windows stand out. Chewing and nipping usually peak during teething, from about 3 to 7 months. Rough play lasts longer: the ASPCA notes it is common in kittens and young cats up to about 2 years old.

The fix is to give those teeth a better target. VCA Animal Hospitals advises against using your hands as toys and recommends wand or fishing-rod toys instead, so a kitten can stalk, pounce and bite without touching you. Put wand toys away after each session, because VCA warns that swallowed string can cause severe intestinal damage.

If your kitten grabs your hand anyway, interrupt the game and redirect the bite to a toy. Consistency matters more than any single session, and our guide to interactive cat toys shows how to play in a way kittens actually engage with.

What to Feed a Teething Kitten

Teething does not call for a special diet. Keep feeding a complete kitten food made for growth. If crunching seems to hurt, offer wet food or soften kibble with a little warm water for a few days, as Cats Protection suggests.

Most kittens go back to crunching normally once the sore tooth is out. If your kitten skips meals or seems to be losing weight, call your vet rather than waiting it out.

Never Pull a Loose Baby Tooth

Can you pull a kitten's loose tooth? No. Baby teeth fall out on their own as the adult tooth pushes through, so there is nothing to gain from pulling, and tugging on a sore mouth hurts and can make your kitten dread having its mouth handled.

Instead, keep offering soft toys and softened food so the loose tooth can work free naturally.

If a baby tooth is still firmly in place while the adult tooth comes in beside it, that is a job for your vet, not for fingers at home.

Start Dental Care While Your Kitten Is Teething

Teething is a good time to get your kitten used to having its mouth handled, which makes lifelong care much easier. Cornell's Feline Health Center calls regular brushing the best way to prevent gingivitis, and notes most cats can be trained to accept it.

When should you start brushing a kitten's teeth? Start gentle mouth handling as soon as you bring your kitten home, and move to regular brushing once the adult teeth are in. Some veterinarians suggest using the teething months to get your kitten used to a brush rather than to brush thoroughly, while Cats Protection advises against brushing during teething because it will hurt. Either way, the goal right now is handling, not scrubbing.

1. Lift the lip and touch the gums with a clean fingertip for a few seconds
2. Let your kitten lick a dab of enzymatic cat toothpaste off your finger so the taste becomes a treat
3. Once your kitten is relaxed, gently wipe the outer tooth surfaces with a soft finger glove dental wipe, skipping any red or sore spots
4. Stop before your kitten squirms, and end with praise or play

Only use toothpaste labeled for cats, because Cornell warns that human toothpaste is not safe for cats. A poultry-flavored enzymatic toothpaste made for cats gives you a treat-like first step now and the paste you will brush with later.

How to Brush Your Kitten's Teeth

Once the adult teeth are in and your kitten is calm about mouth handling, move to a small, soft brush. A dual-ended cat toothbrush gives you a small head for little mouths, or you can keep using a finger brush if your kitten prefers it. Petful's cat teeth cleaning guide adds tips for keeping it up once the adult teeth are in.

• Hold your kitten in your lap or on a stable surface, facing away from you
• Lift the lip and brush the outer surfaces along the gumline, where plaque builds up
• Work on a few teeth at a time and build up over several sessions
• Aim for daily brushing once the habit is set, as Cornell recommends

If your kitten fights the brush, go back a step for a few days. Taking care of your kitten's teeth this way pays off later, and our guide to cat teeth cleaning covers the professional care adult cats may need.

What Do Kitten Teeth Look Like?

Kitten teeth are small, thin and needle-sharp, which is why a kitten's bite feels like pinpricks. There are 26 of them, and the baby incisors have pointed tips. Adult cat teeth are larger and sturdier, and the adult incisors are slightly wider with flat edges.

For the full breakdown of adult teeth by type and jaw, see our guide to how many teeth cats have.

What a Lost Baby Tooth Looks Like

A lost baby tooth is tiny, thin and white, with a sharp tip. It usually has little or no root, because the root dissolves before the tooth comes out, so it can look like a hollow shell and is easy to mistake for a crumb.

In the mouth, you may see a small gap, a pink or slightly bloody spot where the tooth was, or the tip of the adult tooth already showing. That is what a kitten's tooth falling out looks like when everything is going normally.

If you find a tooth, there is nothing you need to do with it. Check your kitten's mouth for the matching gap: between about 3 and 7 months, that is expected. A tooth that turns up after about 7 months, or a chipped piece with a jagged edge, is not routine teething and is worth a vet check.

Will You See Your Kitten's Teeth Fall Out?

Probably not. Baby teeth usually fall out while a kitten is eating or chewing, and most kittens simply swallow them, which VCA says is common and Cats Protection describes as completely harmless. You might find one on a toy, in the food bowl or on bedding, but finding none at all is normal.

So where do cats' baby teeth go? Usually down with a meal, without your kitten noticing. Because you will rarely catch a tooth coming out, the better way to track progress is a quick weekly look in your kitten's mouth: new gaps and bigger, flat-edged front teeth tell you teething is moving along.

Kitten Teeth Age Chart

Because teeth come in on a predictable schedule, shelters and vets estimate a young kitten's age based on which teeth are showing. You can use this kitten age by teeth chart the same way, from newborn to adult cat.

Are kittens born with teeth? No. Newborns have only gums, and the first baby incisors break through at about 2 to 4 weeks, according to the Merck Veterinary Manual. The baby premolars follow at about 5 to 6 weeks.

The front teeth are the easiest clue. The ASPCA notes that baby teeth are a little smaller with pointed tips, while adult incisors are slightly wider with flat edges. Once an adult cat has all 30 permanent teeth, telling its age by teeth becomes far less accurate, as Merck explains.

Retained Baby Teeth and When to See a Vet

A baby tooth that is still in place when its adult replacement comes in is called a retained, or persistent, deciduous tooth. VCA Animal Hospitals says the upper canines are most often affected, followed by the lower canines and then the incisors.

The problem is crowding. A stuck baby tooth forces the adult tooth to grow at the wrong angle, traps food and debris, and sets up tartar, gum disease and a painful bite. Merck's guidance is that a baby tooth should be extracted once its adult successor has started to erupt.

Do not wait for the spay or neuter surgery. VCA advises against waiting until your kitten is spayed or neutered to have a retained baby tooth removed, because early extraction lets the adult tooth move into its proper position.

VCA also suggests a weekly mouth check until your kitten is about 7 to 8 months old. The rule of thumb is simple: two teeth in one spot means a vet visit now.

For everything else you might notice during teething, this side-by-side guide shows where normal ends:

After teething ends, losing teeth is never normal. Adult teeth do not grow back, so a cat older than about 1 year whose tooth fell out, or a kitten that broke a tooth, needs an exam. Common causes of cat tooth loss include tooth resorption, gum disease that starts as gingivitis, stomatitis and a broken tooth, often flagged first by bad breath.
