Feline Gingivitis and Stomatitis: Welfare and Management

Feline Gingivitis and Stomatitis

Dental and oral disease is the most common health problem in cats, with studies suggesting over 70% of cats over 3 years show signs of periodontal disease. Feline gingivostomatitis (FGS) — severe chronic inflammation of the gums and oral mucosa — represents the most painful and welfare-significant end of this spectrum. Understanding and addressing feline oral health is a major veterinary welfare priority.

Spectrum of Feline Oral Disease

Oral disease in cats ranges from mild gingivitis (gum inflammation) through periodontitis (deep tissue disease), to feline chronic gingivostomatitis (FCGS) — a severe, debilitating condition causing persistent oral pain. FCGS involves intense inflammation of the gingiva, alveolar mucosa, and caudal oral mucosa, often with ulceration and severe discomfort.

Welfare Impacts

Oral pain profoundly affects feline quality of life. Signs of oral discomfort include: difficulty eating, pawing at the mouth, dropping food, drooling (sometimes blood-stained), reduced grooming, weight loss, behavioural changes including aggression or withdrawal, and vocalisation during eating. Cats stoically hide pain, meaning owners often underestimate the severity of their pet's discomfort.

Causes and Risk Factors

FCGS pathophysiology involves an aberrant immune response to bacterial plaque antigens, often with involvement of feline calicivirus (FCV) and feline herpesvirus. Immune dysregulation appears central. Breeds with crowded dentition and cats with poor dental hygiene are at increased risk. FeLV and FIV infection increase susceptibility.

Diagnosis

Thorough oral examination under anaesthesia, including dental radiographs, is essential for accurate diagnosis and treatment planning. Biopsy may be needed to exclude neoplasia. Blood and urine testing screens for systemic disease. FCV and FIV/FeLV testing guides prognosis.

Treatment Options

• Full-mouth dental extraction: The most effective treatment for FCGS. Studies show 60-80% of cats achieve complete resolution or significant improvement after full extraction. Remaining teeth maintain chronic antigenic stimulation
• Partial extraction: Extraction of premolars and molars with retention of canines achieves good results in some cases
• Medical management: Immunosuppressive therapy, cyclosporin, and recombinant feline interferon omega provide temporary relief but rarely achieve cure
• Laser therapy: CO2 laser treatment reduces inflammation and improves healing in post-extraction cases
• Corticosteroids: Provide short-term relief but long-term use causes significant side effects

Pain Management

Multimodal analgesia using NSAIDs, opioids, and local anaesthetic blocks is essential perioperatively. Post-extraction pain management with meloxicam or buprenorphine ensures comfortable recovery. Long-term pain monitoring using validated feline grimace scales and behavioural assessment helps assess treatment outcomes.

Prevention and Home Care

Daily tooth brushing with cat-appropriate toothpaste is the gold standard for plaque control but requires patience in training. Dental diets, water additives, and dental chews provide benefit when brushing is not possible. Regular dental checks at annual vaccination appointments enable early disease detection. Kittens benefit from early dental hygiene training when most compliant.
