Dog Dental Disease Prevention and Welfare

Dental disease is the most common health problem in adult dogs, causing chronic pain that is frequently unrecognised; prevention and treatment dramatically improve quality of life.

Key Facts

An estimated 80% of dogs over three years of age have clinically significant periodontal disease
Periodontal disease causes chronic pain that dogs typically mask through behavioural adaptation
Dental disease is associated with systemic health problems including cardiac and kidney disease
Daily tooth brushing is the most effective home prevention method, reducing plaque accumulation by 70%
Professional dental cleaning under anaesthesia is necessary to treat established periodontal disease
Dental chews, water additives, and dental diets have varying levels of evidence for plaque reduction

Welfare Considerations

Dental disease is a silent epidemic in companion dogs. The chronic pain caused by periodontal disease — inflamed gums, loose teeth, and dental root infections — is often invisible to owners because dogs continue to eat and behave normally despite significant pain. Behavioural changes attributed to aging such as reduced playfulness, decreased appetite for hard food, and irritability often reflect unrecognised dental pain. Recognition and treatment of dental disease can be transformative — owners regularly report dogs becoming more playful, energetic, and engaged after dental procedures that resolved chronic pain. Prevention through daily tooth brushing, begun in puppyhood, is the single most effective dental welfare intervention available to dog owners.

What You Can Do

Begin tooth brushing training in puppyhood using dog-specific toothpaste and positive reinforcement
Have your dog's teeth professionally examined at every annual health check
Seek professional dental cleaning under anaesthesia if your vet identifies significant periodontal disease
Provide dental chews with the VOHC (Veterinary Oral Health Council) seal of approval
Never give hard bones or antlers that can cause tooth fractures
Be alert to subtle signs of dental pain including pawing at the face, reluctance to chew hard food, and behaviour changes
