Cat Dental Disease and Quality of Life

Dental disease causes significant chronic pain in cats that profoundly affects eating, behaviour, and quality of life — but the stoic nature of cats means the problem frequently goes unrecognized.

Key Facts

Periodontal disease is the most common disease diagnosed in cats, affecting over 70% of cats over three years old.
Tooth resorption, affecting 30-40% of adult cats, involves progressive destruction of tooth structure from the inside out.
Cats typically continue eating despite severe dental disease, masking the extent of their pain from owners.
Dental radiography is essential for identifying tooth resorption and subgingival disease invisible to oral examination alone.
Cats that undergo dental treatment frequently show marked behaviour and personality improvements, revealing the chronic nature of pre-treatment pain.

Welfare Considerations

Cat dental disease is a silent welfare epidemic: millions of cats live with chronic oral pain that their owners do not recognize because the cats continue to eat and do not visibly complain. The dramatic improvements in demeanour, activity, and appetite reported by owners after dental treatment in cats retrospectively reveal the severity of pre-treatment discomfort. Proactive dental assessment at every veterinary visit and early intervention are the foundations of feline dental welfare.

What You Can Do

Ask your vet to examine your cat's mouth at every wellness visit and request dental radiography if disease is suspected.
Begin dental care early in life — kittens and young cats can be acclimated to brushing more readily than older cats.
Do not delay recommended dental procedures — dental pain is real and worsens progressively without intervention.
Monitor for signs of dental pain including drooling, pawing at face, chewing on one side, and changes in food preference.
