Most Common Vet Visits: Dental Disease / Periodontitis / Tooth Infections

Dental disease is the most common health condition diagnosed in dogs and cats, with studies suggesting that up to 80% of dogs and 70% of cats show signs of oral disease by age three. Despite how widespread it is, dental disease is also one of the most underappreciated threats to pet health. Most owners don’t realize their pet has a problem until it has progressed significantly — because animals instinctively hide pain and discomfort, especially in the mouth.

The Stages of Periodontal Disease

Periodontal disease is a progressive condition that begins with plaque — a sticky film of bacteria that forms on tooth surfaces every day. If not removed, plaque hardens into tartar (also called calculus) within days. The bacteria in plaque and tartar then attack the gums, leading to gingivitis, the earliest and most reversible stage of periodontal disease. As disease progresses, it moves below the gumline, damaging the ligaments and bone that anchor the teeth. By Stage 3 and 4, there is moderate to severe bone loss, deep pockets around the teeth, and often tooth root exposure. Teeth may be loose, infected, or acutely painful. Bacteria from infected tooth roots can enter the bloodstream and reach the heart, kidneys, and liver — making dental disease a systemic concern, not just a mouth problem.

Signs Owners Often Miss

Because pets rarely stop eating even when their mouths are painful, owners often assume everything is fine. Signs of dental disease can be subtle: bad breath beyond normal “dog breath,” yellow or brown buildup on the teeth, drooling, pawing at the mouth, reluctance to chew hard food or toys, dropping food while eating, facial swelling, or rubbing the face along the floor. Blood-tinged water in a water bowl is another clue. Any of these signs warrants a veterinary dental evaluation.

What Happens During a Professional Dental Cleaning

A professional veterinary dental cleaning — properly called a Comprehensive Oral Health Assessment and Treatment (COHAT) — is performed under general anesthesia. This is not optional: a pet must be anesthetized to allow a thorough, safe examination of every tooth and all surfaces below the gumline where disease is most dangerous. Tartar is scaled away using ultrasonic and hand equipment, the teeth are polished, dental X-rays are taken to evaluate roots and surrounding bone, and any teeth with significant disease may be extracted. The result is a truly clean, healthy mouth — not just a cosmetically improved one.

Home Care Between Visits

Daily tooth brushing is the gold standard for maintaining dental health between professional cleanings. Use a pet-safe enzymatic toothpaste — never human toothpaste, which contains fluoride and xylitol, both toxic to pets. Dental chews, water additives, and specially formulated dental diets can serve as supplements to brushing but are not replacements for it. Look for products with the Veterinary Oral Health Council (VOHC) seal of acceptance.

Systemic Risks of Untreated Dental Disease

Research in both human and veterinary medicine has established links between chronic periodontal disease and systemic health problems. Oral bacteria that enter the bloodstream can deposit on heart valves, contributing to heart disease. The kidneys and liver must constantly filter circulating bacteria, increasing the risk of organ damage over time. Treating dental disease isn’t just about fresh breath — it’s about protecting your pet’s overall health and potentially adding years to their life.
