How Common Is Dental Disease in Cats?
Feline dental disease is one of the most prevalent health conditions seen in veterinary practice. Research consistently shows that more than 70 per cent of cats over the age of three have some form of dental disease, yet the majority receive little or no dental care at home. Cats are also notoriously good at hiding discomfort, which means dental problems frequently go undetected until they are well advanced.
The consequences of untreated dental disease extend well beyond a sore mouth. Chronic oral infection places a continuous burden on the immune system and has been linked to damage to the kidneys, liver, and heart over time. For a long-lived companion animal, this matters enormously. Getting on top of your cat's dental health — sooner rather than later — is one of the most meaningful investments you can make in their long-term wellbeing.
Common Feline Dental Conditions
Gingivitis
Gingivitis is inflammation of the gums, caused by the accumulation of plaque — a soft, sticky film of bacteria — along the gum line. In its early stages, gingivitis is reversible with thorough cleaning and improved home care. Left unchecked, it progresses to periodontitis, where the infection spreads to the structures supporting the tooth, causing irreversible damage.
Periodontal Disease
Periodontal disease is the most common dental condition in cats. As plaque hardens into tartar and infection deepens, the ligaments and bone anchoring the teeth are progressively destroyed. Affected teeth become loose and painful, and extraction is often the only humane option by the time owners notice a problem.
Tooth Resorption
Tooth resorption is a condition unique to cats and is unfortunately extremely common — it is estimated to affect around 30 to 40 per cent of adult cats to some degree. In this condition, cells called odontoclasts begin to erode the tooth structure from the inside or at the root surface. The cause is not fully understood, but the result is progressive destruction of the tooth. Affected teeth can appear normal on the surface initially, making the condition difficult to detect without dental X-rays.
Cats with tooth resorption often show signs of pain when eating — flinching, dropping food, or avoiding one side of the mouth — but many suffer in silence. Treatment depends on the type and extent of resorption and usually involves extraction of the affected tooth.
Signs of Dental Pain in Cats
Cats rarely cry out in pain, even when suffering significantly. Learning to recognise the subtler signs of dental discomfort is essential for owners:
- Reluctance to eat, particularly hard food, or preference for eating on one side of the mouth
- Dropping food from the mouth while eating
- Pawing at the face or mouth
- Reduced grooming, or conversely, excessive pawing at the face
- Persistent bad breath (halitosis)
- Drooling, sometimes blood-tinged
- Changes in behaviour such as withdrawal, irritability, or reduced activity
- Visible redness along the gum line or obvious brown tartar on the teeth
Any of these signs warrants a veterinary appointment. Pain from dental disease affects quality of life profoundly, and many owners are surprised at the transformation in their cat's energy and appetite following appropriate dental treatment.
Brushing Your Cat's Teeth at Home
Brushing remains the gold standard for home dental care and, whilst it requires patience to introduce, many cats do accept it with gentle, consistent training.
Use only toothpaste specifically formulated for cats. Human toothpaste contains fluoride and often xylitol, both of which are toxic to cats. Cat toothpastes come in flavours such as chicken or seafood, which most cats find more palatable. Do not use dog toothpaste on a cat without checking it is appropriate for feline use.
A small, soft-bristled finger brush is usually the most practical choice for cats. Introduce the process gradually:
- Begin by allowing your cat to lick toothpaste from your finger, with no brushing at all, for several days.
- Progress to gently touching the outer surfaces of the front teeth with a paste-covered finger.
- Introduce the finger brush and increase the areas covered gradually, always keeping initial sessions very brief.
- Reward your cat calmly after each session — a small treat or favourite activity helps build positive associations.
Daily brushing is the ideal. Even three to four sessions per week provides significant benefit. Once-weekly brushing, while better than nothing, is unlikely to prevent progressive disease on its own.
Dental Diets and Supplementary Products
For cats that will not tolerate brushing — and there are many — dental diets and other products can provide a degree of additional protection:
- Dental prescription diets, such as those carrying the VOHC (Veterinary Oral Health Council) seal, are formulated with larger kibble and specific fibre arrangements that encourage chewing and mechanical plaque removal.
- Dental treats with the VOHC seal offer a similar mechanical benefit in a more palatable format.
- Water additives and dental gels containing ingredients such as chlorhexidine can help reduce bacterial load. These are best used as supplements alongside other measures.
Speak to your vet or veterinary nurse about which products are best suited to your cat. The market contains many products making dental claims, but only those with independent evidence of efficacy — such as the VOHC seal — can be relied upon.
Professional Dental Cleaning Under Anaesthesia
Professional dental cleaning in cats must be performed under general anaesthesia. This is non-negotiable. Conscious dental scaling — using dental instruments in an awake or lightly sedated animal — is not only distressing and potentially dangerous for the cat, but it is also clinically inadequate, as it cannot address the critical area below the gum line where disease originates.
Under anaesthesia, the vet or veterinary dental specialist can thoroughly scale and polish all tooth surfaces, probe the gum pockets around each tooth, and take dental X-rays to identify tooth resorption, root disease, and bone loss that are invisible to the naked eye. Teeth requiring extraction can be removed at the same appointment.
How frequently a professional clean is needed varies between cats. Annual dental health checks, included in most routine vaccination appointments, allow your vet to monitor progression and advise on timing. Cats with moderate disease or poor home care may benefit from a professional clean every twelve to eighteen months; those with excellent home care may need one less frequently.
If your cat is older or has health concerns, a pre-anaesthetic blood test to assess organ function is standard practice and helps ensure the procedure is as safe as possible.
Starting Early and Staying Consistent
The ideal time to introduce dental care is during kittenhood, when cats are at their most adaptable. However, older cats can learn to tolerate brushing too — it simply requires more patience and shorter initial sessions. Whatever the age of your cat, beginning now is better than waiting.
Regular dental care, combined with annual professional check-ups, is the most effective strategy for keeping your cat's mouth healthy throughout their life. A pain-free mouth means a happier, more comfortable cat — and that is something every owner can work towards.
