Dog Periodontal Disease and Welfare

Periodontal disease affects the majority of adult dogs and causes chronic oral pain that is often missed by owners — regular dental care prevents this entirely avoidable suffering.

Key Facts

Periodontal disease affects approximately 80% of dogs over 3 years old, making it the most common disease in companion dogs.
Plaque accumulation triggers gum inflammation that progresses to bone loss, tooth root exposure, and eventual tooth loss.
Dogs with severe periodontitis show elevated inflammatory markers including CRP that increase systemic disease risk.
Daily toothbrushing is the most effective home dental care, reducing plaque accumulation by up to 70%.
Annual professional dental cleaning under anaesthesia allows full assessment and treatment of disease not manageable at home.

Welfare Considerations

Periodontal disease causes chronic oral pain that most dogs conceal effectively. A dog with severe periodontitis — painful eroded gum tissue, loose teeth, and exposed roots — continues eating and acting relatively normally because stopping eating would be worse. The chronic pain is real and measurable; owners who assume their dog is fine because it is eating are missing the silent suffering of untreated dental disease. Post-dental treatment, owners routinely report their dog becoming more playful, eating better, and engaging more — revealing the suppressed welfare cost of the disease they had been living with.

What You Can Do

Brush your dog's teeth daily with dog-specific toothpaste — even partial compliance reduces plaque and disease risk.
Schedule annual professional dental assessments with your vet, including dental X-rays to assess root and bone health.
Provide dental chews certified effective by the Veterinary Oral Health Council as supplements to brushing.
Do not delay professional dental cleaning out of anaesthesia concern — the welfare cost of untreated periodontal disease exceeds anaesthetic risk in healthy dogs.
