Cat Dental Disease: The Most Common Preventable Welfare Problem

Why periodontal disease affects the majority of cats over three years old and how regular dental care prevents chronic oral pain.

Key Facts

An estimated 70–80% of cats over 3 years of age have some degree of periodontal disease
Periodontal disease causes chronic gingival inflammation, tooth root absorption and jaw bone loss — all painful
Tooth resorption (feline odontoclastic resorptive lesions) affects approximately 50% of cats and causes severe dental pain
Many cats with significant dental disease show no obvious signs — they continue eating despite chronic oral pain
Professional dental cleaning under general anaesthesia is the only way to adequately assess and treat feline dental disease
Daily tooth brushing with veterinary toothpaste is the most effective home prevention method when accepted by the cat

Welfare Considerations

Feline dental disease is one of the most prevalent chronic welfare conditions in companion animals and one of the most consistently under-treated. The assumption that a cat is not in pain because it continues to eat ignores the overwhelming evidence that cats eat through significant dental pain — the drive to eat is stronger than the pain inhibition threshold in most cases. The welfare consequence is that many cats endure years of chronic oral pain before a dental procedure finally reveals and addresses the extent of disease. Post-dental procedure behaviour changes — increased activity, improved appetite, more social engagement — reported by owners after their cat's first professional cleaning confirm retrospectively how much discomfort those cats had been carrying.

What You Can Do

Schedule a dental examination under sedation if your cat has not had one in the past year and is over 3 years old
Begin dental home care as early as possible — kitten-age introduction dramatically increases acceptance of tooth brushing
Use only veterinary toothpaste — human toothpaste contains fluoride and xylitol which are toxic to cats
Ask your vet about dental radiography — tooth resorption and root disease are invisible without X-rays
Consider dental diets and water additives as supplementary prevention if tooth brushing is not accepted
Do not delay recommended dental procedures out of anaesthetic concern for older cats — untreated pain carries far greater risk
