Dental Disease in Cats: A Neglected Welfare Issue

Dental disease affects the majority of adult cats and causes chronic pain that significantly impairs quality of life, yet it remains one of the most underrecognised and undertreated conditions in companion animal medicine.

Key Facts

Periodontal disease affects an estimated 70-80% of cats over three years old to varying degrees
Tooth resorption — progressive destruction of tooth structure — affects up to 40% of adult cats
Cats rarely show obvious signs of dental pain despite significant disease, making owner and veterinary recognition challenging
Behavioural indicators of dental pain include reduced grooming, preference for soft food, reduced play, and facial tension
Treatment requires general anaesthesia for full oral examination and dental radiography — without which diagnosis is incomplete
Cats who have undergone dental treatment for painful teeth often show dramatically improved demeanour owners describe as returning to youth
Home dental care including tooth brushing can reduce but not prevent dental disease accumulation over time

Welfare Considerations

Dental disease is perhaps the most widespread source of chronic, unrecognised pain in companion cats. The masking of dental pain by cats — an evolutionary adaptation that prevents showing vulnerability — means that most affected cats continue to eat, appear normal to owners, and receive no treatment despite experiencing persistent discomfort. The dramatic behavioural transformations seen in cats after treatment of painful dental disease — increased activity, improved grooming, renewed social engagement, weight gain — provide compelling evidence that chronic dental pain was significantly impairing quality of life beforehand. Veterinary dental disease should be assessed at every annual examination using visual scoring and probing; radiography is essential for complete assessment since 60% or more of dental disease is below the gumline and invisible to visual inspection. Financial barriers to dental treatment, which requires general anaesthesia, are real and represent an equity concern in companion animal welfare. Providing owners with accurate information about the prevalence and welfare impact of dental disease improves the likelihood of treatment authorisation.

What You Can Do

Schedule annual veterinary dental examinations and request dental radiography for complete assessment
Monitor for subtle signs of dental pain including facial tension, food preference changes, and reduced grooming
Begin home dental care early in a cat's life when habituation is easiest and most effective
Do not assume that a cat who is eating normally is pain-free — cats eat despite significant dental disease
