Periodontal disease in dogs: doing a dental cleaning properly
9-year-old Toy Poodle with halitosis, heavy calculus and marked gingivitis, with no obvious pain when eating. The owner asks whether the calculus can be removed without anaesthesia, as she has seen offered at a dog groomer's.
What is the most appropriate plan?
chevron_right Show answer and explanation
A. Anaesthesia-free cleaning with hand scaling of the crowns, which removes visible calculus and avoids anaesthetic risk
Periodontal disease lies below the gumline, where you cannot work in a conscious animal. It leaves subgingival plaque, scratches the enamel without polishing and gives a false impression of a healthy mouth while the disease progresses.
B. Systemic antibiotics for two weeks and daily toothbrushing, without a cleaning
Antibiotics do not remove calculus or plaque organised as biofilm and are not routinely indicated. Brushing is prevention, but it does not resolve established calculus or pockets.
C. General anaesthesia with endotracheal intubation (cuff inflated), periodontal probing, full-mouth dental radiographs, supra- and subgingival scaling and polishing
Correct. It is the only way to assess and treat periodontal disease: intubation protects the airway from water and debris, and probing and radiographs detect attachment and bone loss that cannot be seen by eye.
D. General anaesthesia with deep sedation without intubation, to shorten the procedure in an older dog
Without a tube with an inflated cuff, water from the ultrasonic scaler and debris and bacteria can be aspirated and cause pneumonia. A dental cleaning is never done without protecting the airway.
lightbulb Key takeaway
Periodontal stages (PD1 gingivitis; PD2 <25% attachment loss; PD3 25–50%; PD4 >50%) can only be assigned with probing and radiography, not by looking at the crown. AAHA guidelines and the AVDC advise against anaesthesia-free cleaning: it is cosmetic and does not treat the disease.
