Gum Disease in Dogs: Symptoms, Causes, Treatment and Prevention
Gum disease in dogs is one of the most common and most overlooked health issues affecting our furry companions. In fact, up to 80% of dogs over the age of three show signs of periodontal disease. Yet many pet parents don’t realise how this silent condition can impact not just their dog’s mouth, but their entire body!
We’ll walk you through how gum disease develops, what symptoms to watch for and how to treat and prevent it naturally. We’ll also explore the gut-mouth connection and how supplements like dog probiotics and liver support for dogs can play a role in holistic oral health.
What Is Gum Disease in Dogs?
Gum disease, also known as periodontal disease, is an infection and inflammation of the tissues surrounding your dog’s teeth. It starts when food particles and bacteria form a sticky film called plaque. If not brushed away within 24 to 48 hours, plaque hardens into tartar, which irritates the gums and leads to infection.
The Basics of Periodontal Disease
- Plaque forms after meals and sticks to the teeth.
- Tartar builds up and pushes under the gum line.
- Gums become inflamed (gingivitis), then infected (periodontitis).
- Without treatment, bone loss and tooth loss can occur.
How Gum Disease Progresses (Stages)
Stage 1: Gingivitis: Red, swollen gums and bad breath. Reversible with brushing.
Stage 2: Early Periodontitis: Tartar visible, mild gum recession.
Stage 3: Moderate Periodontitis: Loose teeth, bleeding, pain when chewing.
Stage 4: Advanced Periodontitis: Deep infection, bone loss, possible tooth loss.

Why Gum Disease Matters for Your Dog's Health
Gum disease isn’t just about bad breath or yellow teeth, it can affect your dog’s entire body!
More Than Just Bad Breath
Dogs instinctively hide pain, so even if they’re eating normally, they could be suffering from sore gums or loose teeth. Chronic inflammation in the mouth can cause discomfort, irritability and changes in behavior.
The Hidden Dangers Inside the Body
Oral bacteria can enter the bloodstream and travel to vital organs like the heart, liver and kidneys. Chronic gum infections are linked to liver inflammation, a burden on the immune system that many pet owners don’t realize.
Symptoms of Gum Disease in Dogs
Early Warning Signs
- Persistent bad breath
- Red or inflamed gums
- Light bleeding after chewing
- Licking lips or chewing on one side
- Blood on chew toys
Moderate to Severe Symptoms
- Drooling or bloody saliva
- Difficulty eating or avoiding hard food
- Pawing at the mouth or facial sensitivity
- Yellow or brown tartar along gum line
- Loose or missing teeth
- Weight loss
When to Visit the Vet
If you notice bleeding gums, persistent bad breath or your dog avoiding food, it’s time for a vet check! Annual dental exams are essential for spotting early signs and preventing long procedures.

Causes of Gum Disease in Dogs
Plaque and Bacteria Buildup
Leftover food feeds bacteria, which form plaque. Within 48 hours, plaque calcifies into tartar that irritates the gums.
Poor Oral Hygiene Habits
- Irregular or no brushing
- Lack of professional cleaning
- Over-reliance on chew toys
Diet and Nutrition
Let’s clear the air on kibble! While it’s true that dry food isn’t a substitute for brushing, it does have some perks. Dry kibble tends to be less sticky than wet food, which means it’s less likely to cling to teeth and feed plaque-causing bacteria. The crunch can also help gently massage the gum line. Plus, some specially formulated diets include bacteria-fighting nutrients or dental-friendly textures designed to support oral health.
Tip: Worried about hydration? You can always add a splash of water to your dog’s bowl without losing the benefits of dry food.
Breed and Genetic Factors
Small and flat-faced breeds like Chihuahuas, Poodles and Bulldogs are more prone to gum disease due to crowded teeth, as they have less room in their mouth to hold them all! Older dogs are also at higher risk.
Underlying Health Conditions
Dogs with diabetes or immune suppression may struggle to fight off gum infections. Supporting their immune system with probiotics and liver supplements can help.
How Gum Disease Is Treated in Dogs
Professional Dental Cleaning
Performed under anaesthesia, this includes scaling, polishing and checking under the gums. Dental x-rays are ideal to detect hidden damage. In severe cases, antibiotics or tooth extractions may be required.
Concerned about anaesthesia? Modern protocols are safe and closely monitored by your veterinary team!
Home Care for Mild Cases
-
Regular brushing with toothpaste for dogs
-
Vet-approved oral rinses
-
Dental gels or wipes for minor gingivitis
Avoid non-anaesthetic “cleanings” as they don’t reach beneath the gums and can damage teeth.
Aftercare and Maintenance
Post-cleaning, establish a brushing routine and consider supplements to support oral and immune health.
Adding a daily dog probiotic can help balance bacteria in the gut and mouth, which research shows can reduce bad breath and plaque growth.

Prevention: How to Keep Your Dog’s Gums Healthy
Daily Brushing Routine
- Use dog-safe toothpaste (never human)
- Start slow, let them taste, gently brush outer surfaces
- Make it positive and consistent (at least 3 to 4x/week)
Dental Chews and Toys
- Look for VOHC-approved chews
- Avoid overly hard items like antlers or bones
