Periodontal disease in dogs (aka gum disease) is a significant health concern. By the time they're 3 years of age, gum disease affects a majority of canine companions. Although there are usually no symptoms at first, periodontal disease can destroy the teeth, gums and jaw of your dog as it progresses.
Although periodontal disease is common in dogs, it can be treated and sometimes even prevented altogether.
What Is Periodontal Disease in Dogs?
This type of disease affects the structures in the mouth that surround and support teeth — known as periodontal tissues. For dogs, the culprit of periodontal disease is bacteria.
After a dog eats, bacteria start eating any food particles left in their mouth and form a sticky, white-grayish film called plaque. Bacteria in plaque are immediately recognized by your dog's immune system as foreign invaders, and once that happens, their body sends white blood cells to eliminate the invasion. However, if the plaque is left undisturbed, it will thicken and the bacteria release toxins that can lead to:
- Inflamed or red gums (gingivitis)
- Gum loss
- Loss of bone around the teeth
- Tooth loss
Does Periodontal Disease Have Any Complications?
Yes. One complication of periodontal disease is jaw fracture. Over time, inflammation caused by the bacteria can eat away at the jaw bone, weakening it and leading to pathologic fractures (meaning a fracture caused by disease rather than injury). This is especially common in small and toy breed dogs.
Another complication is the formation of an oronasal fistula, an irregular opening between the mouth and the nasal cavity caused by tissue erosion. Also, stemming from inflammation, this periodontal disease complication can lead to chronic nasal discharge and infections.
Bacteria in the mouth can also enter a dog's bloodstream and land in their kidneys, heart and liver. This can cause increased wear and tear on their internal organs and potentially prompt other health problems.
What Are the Signs of Periodontal Disease in Dogs?
Some early signs of gum disease in dogs may include bad breath, tartar (mineralized plaque) on the teeth and a line of red inflammation along the gumline. Unfortunately, the first signs of periodontal disease in dogs are rarely observed by pet parents. By the time the signs are noticeable, gum disease has typically advanced and is painful for a pet.
As the disease progresses, your dog can experience a number of effects including:
- Bleeding or red gums
- Bloody saliva
- Loose teeth
- Lumps in the mouth or under the eyes
- Receding gums
- Nasal discharge or sneezing
Additionally, your dog may have difficulty picking up food, drop food from their mouth or start to chew on one side. They may also become shy and indicate that they don't want to be touched on the head.
How Is Periodontal Disease Diagnosed?
Through an oral exam, a veterinarian will be able to see many of the signs of periodontal disease, such as red gums, plaque and tartar buildup, and tooth loss or mobility. However, if your vet suspects periodontal disease may be in play, they'll recommend your dog undergo a dental cleaning and an X-ray under general anesthesia to fully assess their oral health.
It's a good idea to have your dog examined regularly, between once or twice a year, by a vet for periodontal disease, as early treatment may be able to preserve your pet's teeth. If your vet recommends dental care, follow their recommendations, even if your dog is acting normally.
Is Periodontal Disease in Dogs Preventable?
You can safeguard your dog against gum disease by following a few vet-recommended strategies.
For starters, dogs — just like humans — can benefit from having their teeth brushed twice a day. Brushing helps reduce plaque and bacteria buildup. It's easy to train most dogs to embrace having their teeth brushed. Some pets even grow to love it, as long as it's a gentle process.
Offer your dog tooth-friendly chew toys to play with. Thin, bendy chew strips and soft rubber chews are good choices. Avoid hard chew toys like antlers, hooves, bleached bones or tennis balls. When in doubt, ask your vet if a toy is a safe choice.
How Is Periodontal Disease Treated?
Periodontal disease in dogs is treated the same way gum disease is treated in humans — with a complete cleaning and removal of all the plaque and tartar from the teeth.
The safest and least stressful way to clean above and below the gumline is with your dog under anesthesia. This also allows the vet to completely examine the mouth; remove any loose, broken or infected teeth; and take dental X-rays. If they note an infection in your dog's gums, they may prescribe antibiotics and pain medication.
How Does Nutrition Affect the Likelihood of Gum Disease in Dogs?
Good oral and gum health starts with a healthy body and immune system. As such, feeding your canine companion a quality dog food that's complete and balanced may help deter the common culprits of periodontal disease.
Foods like Hill's Science Diet Adult Oral Care are specifically formulated to help promote healthy teeth and gums. If your dog has problems with plaque and tartar buildup, talk to your vet about therapeutic dental foods like Hill's Prescription Diet t/d that may help reduce plaque and tartar accumulation.
Even though dental diseases are common in dogs, they don't have to be a problem for your pet. By being proactive and working with a veterinarian who can help you manage your dog's oral health, you can ensure your canine friend keeps their sparkling smile well into their golden years.
