Periodontal disease in dogs: real veterinary cases

Periodontal disease is the single most common diagnosis in UK primary-care dogs — 12.5% of all dogs in any given year, and the prevalence rises with age. By the time a dog is 3 years old, the majority have some periodontal disease. It starts as plaque, hardens to tartar, inflames the gums (gingivitis), and progressively destroys the bone holding the teeth in. The end result is tooth loss, chronic infection, and (because mouth bacteria seed the bloodstream) measurable strain on the heart, kidneys, and liver.

Routine prevention — daily brushing with a dog-safe toothpaste, dental chews with the VOHC seal, and an annual professional cleaning under anaesthesia (COHAT — Comprehensive Oral Health Assessment and Treatment) — works dramatically better than waiting for problems. Once a tooth is severely affected, extraction is usually the right call: chronic infection is far worse for the dog than the loss of one tooth.

What vets typically check for

  • Conscious oral exam to grade visible tartar and gingivitis — useful screening, but only sees half the picture.
  • Comprehensive oral health assessment under general anaesthesia — probing every tooth, scaling, polishing.
  • Full-mouth dental radiographs — essential to find bone loss, tooth resorption, and abscesses hidden below the gum line.
  • Extraction of teeth with > 50% attachment loss, mobility, or radiographic disease.
  • Home-care plan: daily brushing, VOHC-approved chews, water additives, and 6-12-month recheck.

  • A Case Report of Periodontal Disease in a Dog

    International Journal of Zoology and Animal Biology · 2025 · Brazil

    Periodontal disease is a common problem in dogs that affects their gums and teeth. It happens when bacteria build up on the teeth, leading to gum inflammation and, if untreated, can cause tooth loss. In this case, a Cavalier King Charles Spaniel had a lot of tartar on its teeth and showed signs of gum inflammation. The vet diagnosed the issue using a physical exam and special i

  • Effectiveness of a Daily Honeycomb-Shaped Dental Chew in Reducing Calculus, Plaque, Gingivitis and Malodor in Dogs.

    Journal of veterinary dentistry · 2025 · United States

    Periodontal disease, which affects the gums and teeth of dogs, is quite common, and many pet owners struggle to keep up with their pets' dental care. A study looked at whether a honeycomb-shaped dental chew could help reduce hardened plaque, calculus, and bad breath in dogs over 60 days. The researchers found that using this chew daily led to a significant decrease in calculus

  • Periodontal Therapy in Dogs Using Bone Augmentation Products Marketed for Veterinary Use.

    Journal of the American Animal Hospital Association · 2017 · United States

    Periodontal disease, which affects the gums and teeth, is very common in dogs. In this case, two dogs came in for a routine dental check-up and cleaning while under general anesthesia. They didn't show any obvious signs of dental problems except for bad breath, but X-rays and other examinations revealed significant bone loss around their lower back teeth. The veterinarians clea

  • Oral-Fluid Thiol-Detection Test Identifies Underlying Active Periodontal Disease Not Detected by the Visual Awake Examination.

    Journal of the American Animal Hospital Association · 2018 · United States

    Periodontal disease in dogs is highly prevalent but can only be accurately diagnosed by performing an anesthetized oral examination with periodontal probing and dental radiography. In this study, 114 dogs had a visual awake examination of the oral cavity and were administered an oral-fluid thiol-detection test prior to undergoing a a full-mouth anesthetized oral examination an

  • Actinomycosis of periodontium, mimicking gingival enlargement – A case report and its management

    Journal of Indian Society of Periodontology · 2023 · IN

    Gingival abscess is a localized, acute inflammatory lesion which is caused by various factors that include microbial plaque infection, foreign body impaction, and trauma. Management includes a simple incision and draining of the purulent exudate along with systemic antibiotics in most of the cases.

Frequently asked questions

Is anaesthesia-free dental cleaning safe?
It's cosmetic only, and every major veterinary dental organisation worldwide advises against it. You can't probe periodontal pockets or take X-rays in a conscious dog, so over half the disease (which is below the gum line) goes undetected. Scaling without polishing also leaves a roughened tooth surface that accumulates plaque faster.
What about brushing?
Daily brushing with a pet-specific toothpaste (never human toothpaste — fluoride is toxic) is by far the most effective home preventive. Every-other-day brushing helps, but daily is the goal. Start slowly with positive associations; most dogs accept it within a few weeks.
Does dental disease really affect the kidneys and heart?
Yes — there's good evidence that chronic periodontal disease seeds the bloodstream with bacteria, increasing the inflammatory load on the kidneys, liver, and heart valves. Several studies link severity of periodontal disease to chronic kidney disease and mitral valve degeneration.
