Feline Dental Disease: Prevention, Treatment, and Welfare

Dental Disease: The Hidden Welfare Crisis in Cats

Dental and periodontal disease is the most common health problem diagnosed in cats, with studies finding clinical evidence of disease in over 70% of cats by 3 years of age. Despite its prevalence, dental disease remains one of the most under-treated welfare problems in companion cats, as owners frequently fail to recognise signs and many cats stoically mask pain until disease is advanced.

Anatomy of Feline Dental Disease

The continuum of feline dental disease begins with plaque accumulation on tooth surfaces. Mineralisation of plaque creates calculus (tartar). Bacteria in plaque and calculus trigger gingival inflammation (gingivitis), characterised by reddening and swelling of gum tissue. Without intervention, periodontitis develops — destruction of the periodontal ligament, alveolar bone, and supporting structures. This deep tissue disease causes irreversible damage and tooth loss.

Tooth Resorption

Feline tooth resorption (TR) — previously called feline odontoclastic resorptive lesions (FORLs) — is an additional painful condition unique to cats. Odontoclasts erode tooth structure at or below the gumline, causing extreme dental sensitivity and pain. Estimated to affect 20-60% of cats over 5 years, TR causes pain that many cats hide through normal behaviour. Extraction of affected teeth is the only effective treatment.

Signs of Oral Pain in Cats

Recognising dental pain requires vigilance as cats instinctively mask discomfort:

• Reduced appetite or preference for soft food
• Dropping food while eating
• Excessive drooling, sometimes blood-tinged
• Pawing at the mouth
• Facial asymmetry (jaw swelling)
• Reluctance to be touched around the face
• Reduced grooming or asymmetric grooming
• Behavioural changes: increased hiding, irritability, reduced socialisation
• Weight loss in chronic severe disease

Diagnosis and Treatment

Thorough dental examination requires general anaesthesia. Full-mouth dental radiographs are essential — they reveal pathology invisible on visual examination and guide appropriate treatment. Tooth extraction, periodontal treatment, and oral surgery are performed under the same anaesthetic.

Many owners are surprised by their cat's transformed behaviour post-dental treatment — becoming more playful, affectionate, and active as chronic pain is relieved. This behavioural transformation demonstrates how profoundly dental pain reduces quality of life.

Prevention Strategies

Daily tooth brushing with veterinary toothpaste is the most effective preventive measure, reducing plaque accumulation by 50-70%. Starting in kittenhood maximises compliance. For cats that resist brushing, dental diets (Hill's t/d, Royal Canin Dental), water additives (approved by VOHC), and dental chews reduce plaque accumulation. Regular veterinary dental assessments at annual health checks identify disease early, when less invasive treatment is possible.
