Understanding Periodontal Disease in Dogs
Periodontal disease stands as one of the most frequent health concerns faced by dogs. This condition involves inflammation and infection of the structures that support your dog's teeth: gums, periodontal ligament, cementum, and alveolar bone. It doesn't just affect the mouth—advanced cases can impact your pet’s overall health.
How Periodontal Disease Develops
The process starts innocently enough. After a meal or snack, bacteria naturally present in your dog’s mouth begin forming a sticky film called plaque on tooth surfaces. If you don’t remove this plaque regularly (through brushing or chewing), it hardens into calculus or tartar. Tartar provides an ideal surface for more bacteria to accumulate, setting off a cycle of inflammation.
The earliest stage is called gingivitis, where only the gums are inflamed. At this point, the process is still reversible with proper care. But if plaque and tartar remain undisturbed, inflammation spreads deeper into the tissues—a stage known as periodontitis. Here’s where things get serious: tissue and bone supporting the teeth start breaking down, eventually leading to loose teeth or tooth loss.
Who Is at Risk?
Periodontal disease doesn’t discriminate by breed or age, but certain dogs are more susceptible:
- Small breeds
- Brachycephalic breeds (dogs with short snouts)
- Dogs with crowded or misaligned teeth
- Seniors (over two or three years old)
- Those with systemic diseases like diabetes mellitus
- Dogs with genetic predispositions or compromised immune systems
A staggering 80-90% of dogs over two or three years old show some degree of periodontal disease.
The Progression: Stages of Periodontal Disease
- Stage 0: Healthy mouth; no signs of disease.
- Stage 1: Gingivitis; gums inflamed but no attachment loss—fully reversible.
- Stage 2: Early periodontitis; up to 25% attachment loss or mild pockets.
- Stage 3: Moderate periodontitis; 25-50% attachment loss.
- Stage 4: Advanced periodontitis; over 50% attachment loss with possible tooth mobility.
Telltale Signs and Symptoms
Your dog can’t tell you when something hurts, but there are clues:
- Persistent bad breath (halitosis)
- Red, swollen, or bleeding gums
- Plaque and tartar buildup visible on teeth
- Gum recession or deep pockets around teeth
- Loose or missing teeth
- Difficult chewing or favoring one side when eating
- Drooling excessively or dropping food from the mouth
- Bleeding in water bowls or on toys after chewing
- Lethargy, irritability, weight loss, reduced appetite, behavioral changes like withdrawal or aggression
The Diagnosis Process
Your veterinarian will start with a conscious oral exam to check for visible tartar and gum inflammation. However, a thorough diagnosis requires general anesthesia so they can probe for pocket depth and take dental radiographs—these reveal bone loss invisible to the naked eye.
Beyond the Mouth: Systemic Effects
If left unchecked, bacteria and inflammatory mediators from advanced periodontal disease can enter your dog’s bloodstream—a process called bacteremia. This may damage vital organs such as the heart, liver, and kidneys over time.
Treatment Options by Stage
- Mild gingivitis (Stage 1): Professional cleaning (scaling/polishing), removal of all plaque/tartar above and below the gum line; daily home care (brushing).
- Mild-moderate periodontitis (Stages 2–3): Deep cleaning/root planing below gum line; local antimicrobials in pockets; continued home care.
- Advanced periodontitis (Stage 4): May require surgery (flap procedures), bone grafts, extraction of unsalvageable teeth; pain management; systemic antibiotics if needed.
Treatments under anesthesia are essential for thorough subgingival cleaning—anesthesia-free cleanings simply don’t reach below the gum line where most problems lurk.
The Importance of Prevention & Home Care
You can do a lot at home to keep your dog’s mouth healthy. Daily brushing with canine-specific toothpaste is best. Other helpful strategies include:
- Dental chews/toys (avoid anything too hard that could break teeth)
- Diets formulated to reduce plaque/tartar (some contain polyphosphates)
- Dental water additives/oral gels approved by veterinary dental authorities (VOHC seal indicates effectiveness))
- Avoiding table scraps that stick to teeth
- Semiannual veterinary dental checkups—more often for high-risk breeds
- Cautious use of adjunctive products like enzymatic toothpaste/herbal rinses
