Cat Dental Disease: A Widespread and Preventable Welfare Problem

Dental disease affects the majority of cats over three years of age and causes chronic oral pain that significantly reduces quality of life, yet remains underdiagnosed and undertreated in companion cat populations.

Key Facts

Studies estimate that over 70% of cats over age three have some degree of periodontal disease
Feline tooth resorption affects up to 50% of cats and causes severe pain as lesions erode tooth structure
Cats rarely show obvious signs of dental pain, often continuing to eat despite significant oral pathology
Dental disease in cats is associated with systemic inflammation linked to kidney and heart disease
Regular dental assessment under anaesthesia is required for accurate diagnosis of feline oral disease
Daily tooth brushing from kittenhood is the most effective prevention but compliance rates in cat owners are very low
Dental chews, water additives and dental diets offer partial benefit as alternatives to brushing

Welfare Considerations

Chronic dental pain in cats represents a significant hidden welfare burden. Cats do not stop eating when they have dental disease — they adapt their eating behaviour and mask their pain, meaning owners often have no indication their cat is in chronic discomfort. Regular veterinary dental assessment is the only way to identify dental pathology early. The consequences of untreated dental disease extend beyond oral pain to systemic inflammation and organ effects that reduce lifespan and quality of life. The prevention message is simple but requires early establishment of tooth brushing habits and annual veterinary dental checks, investments that pay returns across decades of improved welfare for a long-lived companion animal.

What You Can Do

Begin regular tooth brushing with your cat from kittenhood using cat-specific toothpaste
Schedule annual veterinary dental checks as part of your cat health management routine
Ask your vet to perform an oral examination at every routine health check
If your cat shows reduced appetite, head shaking or pawing at its mouth, seek dental assessment promptly
Support veterinary dentistry access through pet insurance that covers dental treatment
