Dental Disease in Dogs: Prevention and Welfare

Dental disease is the most common health problem in dogs, affecting around 80% of dogs over three years of age. It causes chronic pain and can lead to serious systemic health problems if untreated.

Key Facts

Periodontal disease affects over 80% of dogs by age 3
Signs of dental pain include reluctance to eat hard food, pawing at the mouth, and reduced activity
Dental disease increases risk of kidney, liver, and heart disease through chronic bacterial infection
Daily tooth brushing is the most effective preventive measure
Professional dental scaling under anesthesia is often needed once disease is established
Small and brachycephalic breeds are particularly prone to dental crowding and disease

Welfare Considerations

Dental pain is insidious — dogs typically do not show obvious signs of pain until disease is advanced, meaning many dogs live with chronic oral pain that significantly affects their quality of life. Because dental discomfort suppresses appetite and activity, it can be mistaken for normal aging. Regular dental examinations and proactive preventive care, including toothbrushing and appropriate dental chews, are essential welfare responsibilities. Owners should not wait for obvious behavioral changes before addressing dental health.

What You Can Do

Begin tooth brushing training from puppyhood using dog-specific toothpaste
Schedule regular veterinary dental checks (at least annually, more for small breeds)
Provide appropriate dental chews and toys that help reduce plaque buildup
Be alert to subtle signs of dental discomfort including food dropping and head shyness
Do not delay dental treatment if advised by your vet — pain relief is a welfare priority
Ask your vet about dental scoring systems to track your dog's dental health over time
