Most pet owners know that brushing teeth and preventing tartar is important, but what many don’t realize is just how closely dental health is tied to overall well-being. One of the most significant links is between dental disease and heart health. Poor oral hygiene doesn’t just cause bad breath—it can increase the risk of heart disease in both cats and dogs. Understanding this connection can help you take proactive steps to protect your pet’s health.
Why dental disease is common in pets
Dental disease, also called periodontal disease, is one of the most common health problems seen in pets. It begins with plaque buildup on the teeth, which hardens into tartar if not removed. Over time, bacteria invade below the gumline, causing inflammation, infection, and damage to the tissues that support the teeth.
Small-breed dogs and cats are particularly prone to dental problems, but any pet can develop them without regular dental care. By the age of three, most pets show some level of dental disease.
How bacteria affect the heart
When gums become inflamed and infected, harmful bacteria can enter the bloodstream. Once in circulation, these bacteria can travel to vital organs, including the heart. The heart valves are especially vulnerable, and the condition that results—infective endocarditis—can cause long-term damage and even heart failure.
Even when endocarditis does not develop, chronic inflammation from dental disease puts extra stress on the body and may worsen existing heart conditions. This is especially concerning in older pets or those with underlying heart disease.
Signs of dental disease in pets
Dental problems often go unnoticed because pets are experts at hiding discomfort. Some signs to watch for include:
- Persistent bad breath
- Red or bleeding gums
- Yellow or brown tartar on teeth
- Difficulty eating or chewing on one side
- Pawing at the mouth or excessive drooling
- Loose or missing teeth
By the time these signs are obvious, dental disease may already be advanced.
Pets at higher risk of heart complications
Certain pets are more vulnerable to heart problems linked to poor dental health:
- Small-breed dogs like Chihuahuas, Dachshunds, and Toy Poodles, which are prone to both dental disease and heart valve issues
- Older cats with underlying kidney or heart disease
- Pets with weakened immune systems that can’t fight off infections as effectively
For these pets, preventive dental care is especially important.
Preventing dental and heart complications
The good news is that dental disease—and its impact on the heart—can often be prevented. Steps include:
- Regular dental cleanings: Professional cleanings under anesthesia allow veterinarians to remove tartar and bacteria from below the gumline.
- At-home dental care: Daily or frequent toothbrushing with pet-safe toothpaste is the gold standard. Dental chews, rinses, and special diets can also help.
- Routine checkups: Regular veterinary exams include oral evaluations that can catch problems early.
- Addressing issues quickly: Treating gingivitis or loose teeth before bacteria spread helps protect the heart and other organs.
