Dental disease in cats
PetPort EditorialLast reviewed
How do I know if my cat has painful teeth?
Cats hide dental pain almost completely, and most keep eating through it. Look for drooling, chewing on one side, dropping food, turning away after a mouthful, or a sudden preference for wet food. Resorptive lesions — painful cavities at the gumline — affect a large share of adult cats and cannot be seen without an examination.
General guidance for pet parents, not a diagnosis. Every animal is different — confirm anything that concerns you with your veterinarian.
Quick reference
| Resorptive lesions | Affect a large proportion of adult cats |
|---|---|
| Earliest owner-visible sign | Drooling or one-sided chewing |
| Most cats keep eating | Through significant dental pain |
| Proper assessment needs | General anaesthesia, ideally with dental radiographs |
| Red gum margin | Gingivitis — early, and reversible if treated |
| Never use | Human toothpaste on a cat |
What is happening
Feline dental disease covers gum inflammation, tartar and resorptive lesions — cavity-like defects that form at the gumline and expose nerve. They are genuinely painful, extremely common in adult cats, and almost invisible without a proper oral examination.
Signs to watch for
- Drooling, or a wet chin in a cat that was always clean
- Chewing on one side, or dropping food after picking it up
- Bad breath, red gum margins, or a sudden switch away from dry food
What you can do
- Lift the lip and look at the gumline weekly, so changes are noticed early
- Ask for a full oral examination at every annual visit
- Offer wet food while a painful mouth is being investigated
See a vet if
Your cat is drooling, pawing at its mouth, has stopped eating dry food, or has visibly red gums — feline dental pain needs examination under anaesthesia to assess properly.
In India specifically
Home-cooked rice and fish diets are common for Indian house cats and leave soft residue at the gumline. Full dental radiography is available at larger urban clinics but not everywhere, so if your cat is being anaesthetised for dental work, ask in advance whether radiographs are included — resorptive lesions are frequently missed without them.
Common questions
My cat eats normally, so his teeth must be fine?
Not necessarily. Cats keep eating through severe dental pain because refusing food is not something their instincts permit. Normal appetite is not evidence of a comfortable mouth. Owners are frequently surprised by how much livelier a cat becomes after dental treatment.
What are resorptive lesions in cats?
They are cavity-like defects where the tooth structure breaks down at the gumline, exposing sensitive tissue. They are very common in adult cats, genuinely painful, and cannot be filled — the affected tooth needs extraction. They are often only found on dental radiographs.
Can I brush my cat's teeth?
Yes, and it works, but it has to be introduced gradually and never forced. Start by letting your cat lick cat-formulated toothpaste off your finger for several days before a brush appears. Never use human toothpaste. If brushing causes a fight, stop — the stress outweighs the benefit.
Is anaesthesia safe for an older cat's dental work?
For most cats, yes, with pre-anaesthetic bloodwork and proper monitoring. The relevant comparison is not anaesthesia versus nothing, but anaesthesia versus leaving a painful mouth untreated for years. Ask your clinic what monitoring they use and who stays with your cat during recovery.
