Cat dental care
Cat bad breath, gum changes and eating changes
Home dental care is preventive support. Persistent bad breath, inflamed gums, damaged teeth, drooling or changes in eating can move the decision from routine care to veterinary dental assessment.

Changes worth noticing
Persistent bad breath
A temporary food smell is different from persistent unpleasant breath. Ongoing bad breath can accompany dental or oral disease and is a reason to discuss your cat's mouth with a veterinarian rather than relying only on breath-freshening products.
Red, swollen or bleeding gums
Inflamed-looking gums are not simply a cosmetic change. Redness, swelling, bleeding or obvious tenderness can indicate oral disease that home brushing or dental treats cannot diagnose.
Damaged or discoloured teeth
A broken, loose-looking, unusually coloured or otherwise damaged tooth deserves veterinary assessment. Cats can continue eating despite significant mouth discomfort, so normal appetite does not always rule out a dental problem.
Drooling, pawing at the mouth or changed behaviour
New drooling, repeated pawing at the mouth, reluctance to have the face touched, hiding or irritability can be relevant when they occur with other oral changes.
Eating differently
Dropping food, chewing differently, preferring one side, approaching food and backing away, eating less or showing difficulty eating can all justify veterinary assessment.
Home care has a boundary
Toothbrushing, dental diets and other supportive products can help with prevention, but they cannot determine what is happening below the gumline or assess a painful or damaged tooth. When oral changes are persistent or your cat is eating differently, veterinary examination is the appropriate next step.
Seek prompt veterinary help if your cat cannot eat or drink, has substantial facial swelling or bleeding, appears severely unwell, or has any breathing difficulty.
