Dental Disease in Cats: The Silent Pain Most Owners Miss

Dental disease affects over 70% of cats over three years old and is one of the most common sources of unrecognized chronic pain in companion animals.

Key Facts

An estimated 70-85% of cats over 3 years have some degree of periodontal disease
Cats rarely show obvious dental pain signs until disease is severe — jaw-dropping or drooling indicate advanced disease
Tooth resorption (feline odontoclastic resorption lesions) affects approximately 30% of cats and is extremely painful
Subtler signs of dental pain include reduced grooming, preference for soft food, and behavior changes
Annual oral examinations under sedation allow thorough assessment not possible in awake cats
Dental extraction of diseased teeth immediately improves quality of life — cats eat better after extraction than before

Welfare Considerations

Dental disease causes continuous, chronic pain that cats conceal effectively. A cat with severe periodontal disease or tooth resorption may eat normally and appear entirely healthy while experiencing significant daily discomfort. The first evidence many owners notice is behavioral — a subtly quieter cat, reduced play, or mild food preference changes. Under sedation, the full extent of disease becomes apparent. Extraction of diseased teeth is often dramatically restorative — owners frequently report that their cat seems younger and more playful post-dentistry, finally freed from pain they had normalized over years. Annual wellness examinations that include oral assessment are the most important preventive tool.

What You Can Do

Ensure your cat's annual veterinary check includes oral examination and discussion of dental health
Look for subtle signs of dental pain including reduced grooming, food preference changes, and behavior changes
Accept dental radiography recommendations — dental disease under the gumline is invisible without X-rays
Begin home dental care (tooth brushing or dental treats) in kittens before disease develops
