Cat Dental Disease: A Silent Welfare Problem

Dental disease is the most common health problem in adult cats, yet it is frequently underdiagnosed and undertreated. Oral pain significantly impairs quality of life.

Key Facts

Studies suggest that over 70% of cats over three years old have some degree of periodontal disease.
Tooth resorption — where the tooth structure is progressively destroyed — affects approximately 30-40% of adult cats.
Cats rarely show obvious signs of dental pain; they typically continue eating even with severely diseased mouths.
Signs of dental disease include dropping food, favouring one side when chewing, drooling, facial swelling, and behaviour changes.
Untreated dental disease causes chronic pain, spread of bacteria to systemic organs, and accelerated health decline in senior cats.
Daily tooth brushing is the most effective preventive measure but requires patient training from kittenhood.
Dental diets, water additives, and dental treats have evidence supporting their use as adjuncts to professional cleaning.
Professional dental cleaning under general anaesthesia is required for treatment; this is safe in healthy cats of any age.

Welfare Considerations

Dental disease in cats represents a large, chronic welfare burden that is mostly invisible to owners. Cats' stoic nature means they continue eating despite severe oral pain, leading owners and sometimes vets to underestimate the problem. When dental disease is treated — through professional scaling and extraction of diseased teeth — cats typically show dramatic improvements in activity, appetite, and behaviour that retrospectively confirm the degree of suffering they had been experiencing. The welfare case for regular dental checks, preventive care, and prompt treatment of dental disease is compelling. The reluctance of some owners to proceed with anaesthesia for dental procedures because "the cat is old" is often counterproductive — chronic dental pain is far more dangerous to a cat's health and welfare than a professionally managed anaesthetic.

What You Can Do

Include dental assessment in your cat's annual veterinary health check.
Seek prompt treatment if your vet identifies significant dental disease.
Begin tooth brushing or dental care from kittenhood to prevent disease.
Do not assume your cat is comfortable because it continues eating — cats hide dental pain.
Support research into less invasive dental assessment methods for cats.
Spread awareness among fellow cat owners that dental care is a welfare necessity, not a luxury.
