Dental Disease in Senior Cats: Signs, Tooth Resorption and Care
As cats grow older, dental problems can become easier to miss. A cat may continue eating and still have a painful mouth. Persistent bad breath, a change in chewing or a reluctance to have the face touched are not simply normal signs of ageing. They are good reasons to arrange a veterinary check.
What may be happening in your cat’s mouth
Dental disease affects the teeth, gums and supporting tissues. Plaque is a film that builds up on teeth. When it is not removed, it can harden into tartar and contribute to gum inflammation (gingivitis). Over time, inflammation may damage the tissues that hold a tooth in place (periodontitis), leading to discomfort, loose teeth or tooth loss.
Cats also develop tooth resorption, where tooth structure breaks down. It can be painful and may be difficult to recognise at home. This is one reason a mouth should not be assumed healthy just because a cat is still eating. Dental disease can affect comfort, appetite and quality of life; caring for it is about much more than freshening breath.
Signs worth checking
Book a consultation if you notice:
- persistent bad breath
- red, swollen or bleeding gums, or yellow-brown build-up on teeth
- drooling, food falling from the mouth, slower eating or chewing on one side
- pawing at the mouth, head turning while chewing, or a dislike of being touched around the head
- a damaged, loose or missing tooth.
Facial swelling, mouth bleeding, obvious distress, or a cat that cannot eat or drink warrants prompt veterinary advice. Serious breathing difficulty or collapse is an emergency; contact a veterinarian urgently rather than waiting for a routine appointment.
How a dental assessment and treatment may work
At a consultation, the veterinarian can assess the visible mouth and discuss the next step. The treatment plan depends on the dental grade and what is found. A professional scale and polish may be appropriate for early disease. When there is more significant tartar, inflammation, periodontal disease or suspected tooth resorption, dental radiographs and treatment under general anaesthesia may be recommended. Radiographs can show disease below the gumline and within the tooth that cannot be seen during an awake examination.
Dental radiography is available at Highton, Geelong West, Lara and East Geelong. If an affected tooth needs treatment, this may include extraction or another approach chosen for your cat’s individual findings. Our dentistry service is a useful starting point for discussing your cat’s individual needs. Your veterinarian will explain the benefits, risks, preparation, likely treatment and aftercare before a procedure. Pre-anaesthetic blood testing is routinely performed, with exceptions assessed by the veterinarian.
Gentle care at home
Once your veterinarian confirms that your cat’s mouth is comfortable enough for home care, introduce tooth brushing gradually and use only toothpaste or gel made for cats. Human toothpaste is not safe for cats. Keep sessions short and positive; do not force a painful mouth open. Dental diets, chews, water additives or rinses may be useful parts of an individual home-care plan, but they support dental treatment rather than replace it. They cannot resolve established tartar below the gumline or a painful resorptive tooth.
Following a dental procedure, the follow-up plan is matched to the grade and treatment performed. At rechecks, the team can assess healing and comfort and help refine a realistic home-care routine.
Frequently asked questions
Is bad breath normal in a senior cat?
No. Persistent bad breath is a common sign of oral disease and should be checked, particularly if eating, grooming or behaviour has changed.
Can a cat manage after teeth are removed?
Many cats adapt well after necessary treatment, and removing a painful tooth can improve comfort. The best treatment and recovery plan depend on the findings in your cat’s mouth.
If you are concerned about your senior cat’s dental health, book an appointment or contact the Vets of Geelong team. Early assessment can make the next step clearer and help keep your cat comfortable.
