My kitten has a loose tooth — is that normal?
Yes, in most cases this is just normal teething. Kittens start losing their baby teeth as their adult teeth push through, typically somewhere between about three and seven months old, and a loose or missing baby tooth on its own — with no other signs of a problem — is a completely normal part of that process.
Usually not urgent
This is common and often manageable at home — but see a vet if it persists, gets worse, or comes with other changes.
Why kittens' teeth come loose
Baby, or deciduous, teeth are gradually pushed out as the permanent adult teeth erupt underneath them, in broadly the same way children lose their baby teeth as their adult teeth come through.
A kitten producing a small amount of blood-tinged saliva, chewing more than usual on toys or furniture, or dropping a tiny tooth are all normal signs of this process happening, rather than signs of an injury or something wrong with your kitten.
When it's worth a vet check anyway
Occasionally a baby tooth doesn't fall out on its own even after the adult tooth has already come through next to it, which is called a retained or persistent deciduous tooth. This is worth a vet check, since two teeth crowded into the same space can cause problems with alignment or hygiene later on if it isn't dealt with.
A routine kitten vet visit is a sensible time to have this checked as a matter of course, rather than waiting for a specific problem to develop before mentioning it.
Signs that need more urgent attention
Ongoing bleeding that doesn't settle, a kitten who stops eating or seems reluctant to chew, noticeable swelling, or bad breath beyond what's normal for teething are all reasons to see a vet sooner rather than waiting for a routine check to come around on its own.
These signs are less common than straightforward teething, but they're worth knowing about so you're not caught off guard if one of them does turn up unexpectedly one day.
What helps during teething
Appropriate kitten-safe chew toys and dental-friendly treats can give a teething kitten something suitable to chew on, which can ease some of the discomfort that comes with teeth moving and new ones coming through underneath the gum line.
Regular gentle handling of the mouth area from a young age also makes later dental checks, and any brushing you introduce, considerably easier for both of you further down the line as your kitten grows up.
Changes in eating during teething
Some kittens go slightly off their usual enthusiasm for dry food while their gums are sore, preferring something softer for a few days. This is common and usually passes on its own as the new teeth settle in, without needing any change to their normal diet.
If a kitten stops eating altogether, rather than simply eating a little less or more slowly, that's a different and more urgent situation — kittens can become unwell quickly if they go without food for long, and it's worth contacting a vet the same day rather than waiting to see if appetite returns on its own.
How this differs from an adult cat's dental problems
A loose tooth in a kitten is almost always about a baby tooth being replaced, which is a normal developmental process rather than a sign of disease. A loose tooth in a fully adult cat is a different matter entirely, since adult cats don't naturally lose teeth, and any looseness at that stage of life usually points to gum disease or another dental problem that needs a vet's attention.
Knowing roughly how old your cat is, and whether they've already gone through their full teething period, is genuinely useful context if you ever need to describe a dental concern to a vet, since it changes what's likely to be going on.
Setting up good dental habits early
The teething period is a reasonable time to start getting a kitten used to having their mouth handled gently, even briefly, so that later dental checks and any brushing you introduce feel familiar rather than new and stressful.
It's also a good point to ask about dental care generally at a routine vet visit, since early habits — the right toys, appropriate treats, and occasional handling — tend to make dental health easier to manage across your cat's whole life rather than something addressed only once a problem appears.

Common questions
- At what age do kittens lose their baby teeth?
- Most kittens lose their baby teeth somewhere between about three and seven months old, as the permanent adult teeth push through underneath them. The exact timing varies a little between individual kittens.
- Is it normal for a kitten's tooth to bleed a little?
- A small amount of blood-tinged saliva during teething is normal, since a tooth coming loose and falling out can cause minor, brief bleeding. Ongoing or heavier bleeding is worth having a vet check.
- What is a retained baby tooth in a kitten?
- It's when a baby tooth doesn't fall out on its own even after the adult tooth has already come through next to it. It's worth a vet check, since two teeth crowded together can cause problems with alignment or hygiene if left untreated.
- Should I take my kitten to the vet for a loose tooth?
- A single loose or missing baby tooth with no other symptoms is usually normal teething and not urgent, though it's worth mentioning at a routine check. See a vet sooner if there's ongoing bleeding, swelling, or your kitten stops eating.
- Is it normal for a kitten to go off their food a little while teething?
- Yes, some kittens eat a little less enthusiastically or more slowly while their gums are sore, and this usually passes on its own. A kitten who stops eating altogether needs a vet's attention the same day rather than waiting to see.
- Can I find my kitten's lost baby teeth around the house?
- Occasionally, though most owners never actually find them, since kittens often swallow a loose tooth without any trouble while eating or chewing. This is completely normal and isn't something to worry about.
