Dental disease is one of the most common health problems in adult cats, and one of the easiest to overlook because many cats keep eating through considerable mouth pain. The signs are there if you know where to look: in the breath, on the gumline, and in small changes to how a cat approaches and handles food. Catching them early matters because sore teeth and inflamed gums affect eating, grooming and general comfort every single day.
Breath, gums and what you can see
A healthy cat's breath is not sweet, but it should not knock you back. Breath that has become persistently strong or foul is often the first sign owners notice, and it usually reflects bacteria building up around the teeth and under the gumline. If your cat tolerates a gentle lip lift, look for gums that are red, puffy or bleeding at the edge where they meet the tooth, rather than a smooth pale pink. Yellow-brown tartar crusting the large back teeth is another clear marker, as are teeth that look loose, discoloured or broken. Drooling, sometimes with a strand hanging from one side of the mouth, and pawing or rubbing at the face can signal that a particular tooth is hurting. Never force the mouth open; what you can see during a yawn or a relaxed lip lift is enough to justify a proper examination.
Eating behaviour that points to a sore mouth
Cats with dental pain often change technique rather than appetite. A cat may approach the bowl eagerly, then drop pieces of dry food, tilt the head to chew on one side, or swallow kibble whole instead of crunching it. Some switch to favouring wet food, lick at meals instead of biting, or eat well for a few mouthfuls and then walk away. Weight can drift down slowly, and a cat may flinch or pull back if the side of the face is stroked. Because these habits develop gradually, comparing current eating with how the same cat ate months ago is revealing. Note specific observations, such as dropped food on one side of the bowl, rather than a general sense that eating seems different.
Why a mouth check belongs in routine vet visits
Only a veterinary examination can judge what is happening below the gumline, where much dental disease hides. A vet can check each tooth, assess gum inflammation, and explain whether cleaning under anaesthesia or further investigation is appropriate for this cat. Mouth pain also overlaps with other problems, including growths and jaw issues, so assuming tartar is the whole story can delay the right care. If your cat resists having the mouth looked at, say so at booking, because a calm, planned examination is safer for everyone than a struggle. Regular checks matter more as cats age, when dental trouble and other illnesses increasingly travel together.
When mouth signs need prompt attention
Book a visit soon if breath has turned foul, gums look red or bleeding, tartar is building up or eating habits have changed. A cat who stops eating, drools heavily, paws frantically at the mouth, has a swollen face or seems in clear pain needs a prompt appointment rather than a routine one. Mouth pain rarely resolves on its own, and waiting usually means more inflammation and a harder procedure later. Keeping photos of visible tartar and dated notes on eating changes in your KinsLe Pet Passport means the dental history travels with your cat to every check-up and any new clinic.
