My cat has a loose tooth
A loose tooth in an adult cat is not normal and is usually a sign of underlying dental disease, most often gum disease or a condition called tooth resorption, both of which need a vet to examine and treat properly. It is not something to wait out at home, even if your cat seems otherwise fine.
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.
What commonly causes a loose tooth in cats
Periodontal disease — inflammation and infection of the gum and supporting structures around a tooth — is one of the most common causes, and it develops gradually from a build-up of plaque and tartar, often over months or years before a tooth actually becomes loose.
Tooth resorption is another common and specifically feline cause, where the tooth's own structure gradually breaks down from the inside. It is thought to affect a significant proportion of adult cats to some degree and can be painful well before a tooth is visibly loose or missing.
Less commonly, trauma from a fall, a fight, or catching a tooth on something hard can loosen or fracture a tooth suddenly, rather than through gradual disease. This tends to come with other visible signs, like bleeding or a swollen face, rather than being an isolated loose tooth found by chance.
What it commonly looks like
Owners often notice a loose tooth by chance — during a stroke around the mouth, or if a cat drops a piece of food unusually often, chews only on one side, or seems reluctant to eat harder food or dry kibble.
Bad breath, red or swollen gums, drooling, pawing at the mouth, and a general drop in interest in eating can all accompany dental problems, though a cat can also have significant dental disease and show surprisingly few obvious signs, which is part of why regular checks matter.
When to see a vet
Any loose tooth in an adult cat is worth a vet visit rather than waiting to see if it resolves, since dental disease generally does not improve on its own and tends to be more comfortable and easier to treat the earlier it is addressed.
See a vet promptly, rather than at the next routine visit, if your cat stops eating or eats noticeably less, drools excessively, has visible bleeding from the mouth, or seems to be in pain — pawing at the face, reluctance to be touched near the mouth, or a generally withdrawn demeanour.
What a vet visit usually involves
A vet will examine your cat's mouth, and in many cases a dental problem like resorption is only fully assessed under anaesthetic with dental X-rays, since a lot of what is happening to the tooth root cannot be seen or judged from a conscious examination alone.
Treatment depends entirely on the cause and can range from a professional clean and monitoring through to extraction of the affected tooth, which is usually the recommended treatment for advanced resorption or a badly diseased tooth and generally leaves cats far more comfortable afterwards.
Life after a tooth is removed
Most cats manage very well with one or even several teeth missing, and eating usually returns to normal within a short recovery period once any soreness from the procedure has settled. Cats rely far less on chewing to break food down than dogs do, which is part of why the outcome tends to be a good one.
Your vet will usually recommend a period of softer food while the mouth heals, and a follow-up check to make sure the extraction site has healed properly and that no other teeth are showing early signs of the same problem.

Common questions
- Is a loose tooth in a cat an emergency?
- Not usually an immediate emergency in the way a collapse or breathing difficulty is, but it should still be seen by a vet promptly rather than left. If there is heavy bleeding, your cat has stopped eating, or they seem to be in significant pain, treat it more urgently and contact your vet the same day.
- Can a cat's loose tooth fix itself?
- No, the underlying causes of a loose tooth — gum disease or tooth resorption in most cases — do not resolve on their own and generally get worse without treatment over time. A vet visit is needed to diagnose the actual cause and treat it properly.
- Why do cats get tooth resorption?
- The exact cause of feline tooth resorption is not fully understood, though it is a common condition affecting a significant number of adult cats to some degree. It is not caused by anything an owner did or failed to do, and it needs veterinary treatment rather than home management or a change in diet alone.
- Will my cat need the tooth removed?
- It depends on the cause and how advanced the problem is. Extraction is a common and often the most comfortable treatment for a badly affected or resorbing tooth, but your vet can only confirm the right course of action after a proper examination, often including dental X-rays.
- How can I prevent dental problems in my cat?
- Regular vet checks that include the mouth, along with dental care appropriate for your cat such as dental-specific food, chews or brushing where your cat tolerates it, all help slow the build-up of plaque and tartar that leads to gum disease over time. None of it removes the need for a vet to assess a tooth that is already loose.
