Gum Disease in Dogs: The Signs, Prevention and Treatment

Veterinary Dental checks are essential for your Dog.

Your dog's smile can tell you a surprising amount about their health. While many owners regularly check their dog's coat, eyes, ears and paws, dental health is sometimes overlooked. Unfortunately, gum disease in dogs is extremely common and can cause significant pain if it is allowed to progress.

Dog gum disease can begin with something as simple as plaque building up on the teeth. Over time, plaque can harden into tartar, irritate the gums and eventually damage the tissues and bone supporting the teeth. This condition is commonly known as periodontal disease in dogs.

The worrying thing is that dogs can be remarkably good at hiding dental pain. Some will continue eating normally even when they have painful or infected teeth. This is why knowing the signs of gum disease in dogs and providing regular dental care is so important. (PDSA)

In this guide, we look at what causes gum disease in dogs, the symptoms to watch for, how to prevent dog dental disease and what treatment your vet may recommend.

What Is Gum Disease in Dogs?

Gum disease in dogs is inflammation and infection affecting the gums and the structures that support the teeth. It commonly begins with plaque – a sticky layer containing bacteria that forms on the surface of the teeth.

If plaque isn't regularly removed, it can harden into tartar. Tartar provides an uneven surface where more plaque can accumulate, increasing irritation around the gums.

The earliest stage is called gingivitis in dogs. At this point, the gums may become red, swollen and prone to bleeding. Gingivitis is considered reversible when the underlying cause is addressed.

If the problem progresses, inflammation can extend beneath the gum line and affect the tissues and bone supporting the teeth. This is known as periodontal disease and can eventually result in loose or lost teeth. (PDSA)

How Does Gum Disease in Dogs Develop?

The process often happens gradually:

1. Bacteria accumulate on the teeth and form plaque.

2. Plaque begins irritating the gums.

3. Plaque hardens into tartar.

4. The gums become inflamed, causing gingivitis.

5. Infection can develop beneath the gum line.

6. The tissues and bone supporting the teeth can become damaged.

7. Teeth may become loose, painful or require removal.

This means that dog dental care isn't simply about keeping your dog's teeth looking clean. It is about protecting their mouth from painful disease.

What Are the Signs of Gum Disease in Dogs?

Recognising the signs of gum disease in dogs early can make a considerable difference. Unfortunately, some dogs show very few obvious symptoms, particularly during the early stages.

Bad breath is often one of the first things owners notice, but it should not simply be dismissed as "normal dog breath". Persistent unpleasant breath can be a sign of dental disease and should be investigated. (PDSA)

Bad Breath Can Be a Sign of Gum Disease in Dogs

A strong or unpleasant smell coming from your dog's mouth is known as halitosis.

Although occasional doggy breath isn't necessarily a concern, persistent bad breath can indicate plaque, tartar, gingivitis or periodontal disease.

If your dog's breath suddenly becomes much worse, arrange a veterinary check-up rather than trying to cover the smell with treats or dental products.

Red, Swollen or Bleeding Gums

Healthy gums should generally appear moist and pink, although some dogs naturally have darker pigmentation.

Red, swollen or bleeding gums can indicate inflammation and are an important sign of gum disease in dogs.

You may notice blood when your dog chews a toy, eats or has their teeth brushed. Don't assume bleeding is caused by brushing – your vet should assess inflamed gums. (PDSA)

Yellow or Brown Tartar on the Teeth

Tartar is hardened plaque that can appear as yellow, brown or darker deposits on the teeth.

Once tartar has formed, brushing alone won't necessarily remove it. Your vet may recommend a professional dental procedure to assess and clean your dog's teeth properly.

Difficulty Eating or Chewing

A dog experiencing dental pain may:

• Chew on one side of their mouth.

• Drop food while eating.

• Take longer to eat

• Avoid hard food

• Prefer softer food

• Hesitate before picking up food.

• Stop playing with chew toys.

• Appear uncomfortable when chewing.

Some dogs continue eating despite significant dental problems, so a normal appetite doesn't always mean that your dog's teeth are healthy. (PDSA)

Drooling, Pawing at the Mouth or Facial Swelling

Other possible symptoms of dog gum disease include increased drooling, pawing or rubbing at the mouth, and blood in the saliva.

Facial swelling, particularly around the jaw or underneath the eye, can sometimes indicate a tooth-root infection or abscess and should be checked promptly by a vet. (PDSA)

What Causes Gum Disease in Dogs?

Several factors can increase the likelihood of periodontal disease in dogs.

Poor dental hygiene is one of the biggest contributors because plaque is continuously forming on the teeth. Without regular removal, it can develop into tartar and contribute to inflammation.

Age can also play a role, with older dogs generally having a greater risk of dental disease. Breed and mouth shape can also influence susceptibility. Dogs with crowded teeth or certain skull shapes may have areas that are particularly difficult to keep clean. (PDSA)

Dog Dental Disease and Age

Dental disease isn't exclusively an older-dog problem.

Puppies can develop dental problems too, particularly if baby teeth are retained and create overcrowding. As dogs get older, however, the cumulative effects of plaque and tartar can make periodontal disease increasingly likely.

This is why dog dental care should begin early rather than waiting until your dog is a senior.

Breed and Gum Disease in Dogs

Some dogs are more susceptible to dental problems than others.

Small breeds and dogs with crowded mouths can have increased difficulty keeping their teeth clean. Certain breeds, including Toy Poodles, Cavalier King Charles Spaniels, Greyhounds and King Charles Spaniels, are among those identified as being more prone to dental disease. (PDSA)

However, every dog can develop gum disease, regardless of breed or size.

Can Gum Disease in Dogs Affect Their Overall Health?

Severe dental disease isn't simply a cosmetic issue.

The mouth contains large numbers of bacteria, and advanced dental disease can cause inflammation and infection within the tissues surrounding the teeth. Oral bacteria can also enter the bloodstream, which is one reason veterinary professionals take significant dental disease seriously. (VCA)

This doesn't mean that every dog with gum disease will develop problems elsewhere in the body. However, maintaining good oral health is an important part of looking after your dog's overall wellbeing.

How to Prevent Gum Disease in Dogs

The good news is that there are several things you can do to reduce your dog's risk of gum disease.

The most effective approach is to make dental care part of your dog's normal routine.

Brush Your Dog's Teeth to Prevent Gum Disease

Regular tooth brushing is one of the best ways to control plaque.

Ideally, brush your dog's teeth daily using a toothbrush and toothpaste specifically designed for dogs. Human toothpaste should not be used because some ingredients can be harmful if swallowed. (PDSA)

If your dog isn't accustomed to having their mouth handled, introduce brushing gradually.

Start by allowing your dog to taste a small amount of dog-safe toothpaste. Next, gently touch their lips and gums before eventually introducing a toothbrush.

Keep sessions short and positive, rewarding calm behaviour.

If your dog becomes distressed or tries to bite, don't force the process. Speak to your vet or veterinary nurse about alternative approaches to dog dental care.

Use Dog Dental Chews and Toys Carefully

Certain dental chews and toys can help reduce plaque accumulation and form part of a good dental routine.

However, not every chew is suitable for every dog. Extremely hard items can fracture teeth, so avoid giving your dog hard objects such as bones, antlers or other products that could damage their teeth. (VCA)

Always supervise your dog with chews and toys.

Consider Dental Diets and Dental Products

Some specially formulated dental diets, treats and water additives are designed to support oral hygiene.

These should complement rather than replace tooth brushing and professional veterinary care. If you're unsure which products are appropriate, ask your vet for advice.

Arrange Regular Veterinary Dental Checks

Regular veterinary examinations are an important part of preventing dog dental disease.

Your vet can examine areas of your dog's mouth that may be difficult for you to see and identify problems before they become more advanced.

Remember that dental disease can occur beneath the gumline, meaning that what you can see at home may not tell the whole story. (PDSA)

How Is Gum Disease in Dogs Treated?

The appropriate treatment for gum disease in dogs depends on how advanced the condition is and which teeth and tissues are affected.

Your vet will first examine your dog's mouth and may recommend a professional dental procedure.

A thorough dental examination and cleaning generally requires a general anaesthetic because this allows the veterinary team to properly assess the teeth, clean below the gum line and perform dental X-rays where appropriate. (PDSA)

Professional Dog Teeth Cleaning

A veterinary dental procedure may involve removing plaque and tartar, polishing the teeth and examining the gums.

Dental X-rays can be particularly useful because significant portions of a tooth, including the roots and surrounding structures, cannot be properly assessed simply by looking at the visible crown. (PDSA)

Tooth Removal May Be Necessary

If a tooth is severely damaged, loose, infected or no longer adequately supported by the surrounding tissues, your vet may recommend extraction.

Although the thought of your dog having teeth removed can be worrying, removing painful or diseased teeth can significantly improve their comfort and quality of life.

Your vet will discuss the recommended treatment and aftercare with you.

Pain Relief and Antibiotics

Dogs with painful dental disease may require pain relief following treatment.

Antibiotics aren't automatically required for every case of dental disease. Your vet will decide whether they are appropriate based on the individual dog and the type of infection or procedure involved. (PDSA)

Can You Treat Gum Disease in Dogs at Home?

Home dental care is extremely useful for preventing gum disease in dogs, but established periodontal disease should not be treated solely at home.

Brushing can help prevent new plaque from accumulating, but it cannot reverse significant damage that has already developed beneath the gum line.

If your dog has red or bleeding gums, substantial tartar, loose teeth, facial swelling, persistent bad breath or signs of oral pain, arrange a veterinary examination.

Avoid attempting to scrape tartar off your dog's teeth yourself. You could injure the gums or damage the teeth, while leaving disease beneath the gum line untreated.

When Should You Take Your Dog to the Vet?

Contact your vet if you notice any signs of dog gum disease, particularly:

• Persistent bad breath

• Red or swollen gums

• Bleeding gums

• Heavy tartar accumulation

• Loose or broken teeth

• Excessive drooling

• Blood in the saliva

• Difficulty eating

• Dropping food

• Pawing at the mouth

• Facial swelling

• A sudden reluctance to chew

• Signs that your dog is experiencing mouth pain

Seek prompt veterinary attention if your dog is unable to eat because of mouth pain or develops significant facial swelling. (PDSA)

Frequently Asked Questions About Gum Disease in Dogs

Is Gum Disease in Dogs Painful?

Yes. Gum disease in dogs can be painful, particularly once inflammation and infection progress beyond the early stages.

Unfortunately, dogs don't always show obvious signs of pain. Some continue eating normally despite having significant dental problems, which is why routine dental examinations are important. (PDSA)

Is Bad Breath Normal for Dogs?

A mild doggy smell isn't unusual, but persistent, strong or unpleasant breath shouldn't simply be considered normal.

Bad breath can be a sign of plaque, tartar, gingivitis or periodontal disease and is worth discussing with your vet.

Can Gum Disease in Dogs Be Reversed?

Early gingivitis can often be reversed when plaque and tartar are appropriately addressed, and an effective dental-care routine is established.

More advanced periodontal disease can permanently damage the tissues supporting the teeth, meaning professional veterinary treatment may be necessary. (VCA)

How Often Should I Brush My Dog's Teeth?

Daily brushing is ideal because plaque continually forms on the teeth.

If daily brushing isn't possible, regular brushing is still preferable to none. PDSA recommends regular daily brushing, or at least three times a week, to significantly reduce the risk of serious dental problems. (PDSA)

Can I Use Human Toothpaste on My Dog?

No. Use toothpaste specifically formulated for dogs.

Dogs swallow toothpaste rather than rinsing and spitting it out, so human toothpaste isn't an appropriate substitute. (PDSA)

Final Thoughts on Gum Disease in Dogs

Gum disease in dogs is common, but it isn't something that should be accepted as an inevitable part of owning a dog.

Regularly checking your dog's mouth, brushing their teeth, providing appropriate dental products and arranging veterinary check-ups can all help protect their teeth and gums.

Perhaps most importantly, don't wait for your dog to stop eating before taking dental problems seriously. Dogs can hide oral pain remarkably well, and early intervention can help prevent minor gum inflammation from developing into painful periodontal disease.

A few minutes spent on dog dental care each day could make a significant difference to your dog's comfort, health and quality of life for years to come.
