Periodontal Disease in Dogs: How to Spot It Before It Causes Pain

Periodontal disease is one of the most common but also one of the most overlooked health problems in dogs. At our London vet practices, we see countless pets each year suffering from preventable dental issues, many of which have been developing quietly for months or even years. The good news? Early detection makes a world of difference.

In this blog, we explain what periodontal disease is, why early diagnosis matters, and how London dog owners can spot the warning signs before the condition becomes painful or severe.

What Is Periodontal Disease?

Periodontal disease is a progressive infection of the tissues that surround and support your dog’s teeth. It begins when plaque, a sticky film of bacteria, builds up on the teeth. If plaque isn’t removed through brushing or chewing, it hardens into tartar, which irritates the gums and leads to inflammation, infection, and ultimately, tooth and bone loss.

The disease progresses in four stages:

1. Gingivitis – Red, swollen gums; reversible with treatment.
2. Early Periodontitis – Tartar buildup and gum recession begin.
3. Moderate Periodontitis – Damage to tooth-supporting structures.
4. Advanced Periodontitis – Severe infection, loose teeth, and pain.

Catching the disease at stages 1 or 2 makes treatment easier, safer, and far more effective.

Why Early Detection Is So Important

Early periodontal disease may be subtle, but it can quickly escalate if untreated. Once bacteria start affecting the gums, they can spread deeper into the tissues and even enter the bloodstream, impacting the heart, liver, and kidneys.

Spotting the condition early helps prevent:

• Dental pain
• Tooth loss
• Infections
• Costly dental procedures
• Long-term health complications

For busy London dog owners, regular preventative healthcare checks and early awareness are key to protecting your dog’s wellbeing.

Early Signs of Periodontal Disease in Dogs

Dogs often hide pain, which can make early periodontal disease easy to miss. However, there are several signs you can look for at home. If you notice any of the following, it’s a good idea to book a dental check at your nearest London Vet practice.

1. Persistent Bad Breath

A little doggy breath is normal, but a strong, unpleasant smell can be one of the earliest signs of gum disease.

2. Red or Irritated Gums

Healthy gums should be pink and smooth. Redness, swelling, or bleeding, even slight, may indicate gingivitis.

3. Yellow or Brown Tartar

Tartar often forms along the gumline. Left untreated, it traps bacteria and accelerates periodontal disease.

4. Drooling or Dropping Food

Dogs experiencing oral discomfort may chew differently, favour one side of the mouth, or drop food while eating.

5. Changes in Chewing or Eating Habits

A reluctance to eat dry kibble, picking at food, or slower eating can point to discomfort.

6. Pawing at the Mouth

This can indicate mouth pain or irritation.

7. Behaviour Changes

Irritability, lower energy, or avoiding being touched around the face are common signs when dental pain is present.

If you notice any combination of these signs, early evaluation is essential.

How Our Teams across London Diagnose and Treat Early Periodontal Disease

To diagnose and treat early periodontal disease, we use a combination of:

• Comprehensive oral exams
• Dental X-rays, which detect hidden disease below the gumline
• Professional dental cleaning under safe general anaesthetic
• Scaling and polishing, removing plaque and tartar above and below the gums
• Home-care plans tailored to your dog’s breed, age, and lifestyle

Early-stage periodontal disease is highly treatable, and in many cases, even reversible.

How to Prevent Periodontal Disease at Home

Good oral hygiene starts at home. Our veterinarians recommend:

Daily or Regular Tooth Brushing

Use a dog-safe toothpaste and a soft brush. Even brushing three times a week has a big impact.

Dental Chews and Toys

Look for VOHC-approved products that help reduce plaque.
