What Organs Does Bad Dental Hygiene Affect in Dogs?

Dog owners need to practice good oral hygiene for their pets to protect them against not only dental problems and gum disease, but organ damage that can result from poor dental care. Gums and teeth that become infected can allow bacteria to enter the bloodstream. Left untreated, the bacteria can cause vital organ damage, which can be painful, expensive to care for and even deadly if not medically treated.


Bacteria can enter your dog's bloodstream when gum tissue is soft and a tooth’s root structure is weakened. Advanced periodontal disease can inflame the animal’s heart valves, a condition known as endocarditis. Coronary artery disease is also associated with canine and feline gum conditions. Some bacteria can narrow artery walls and decrease blood flow, while other bacteria can cause blood clots to form and damage the heart muscle.


The liver is responsible for purifying blood, facilitating the digestive process and eliminating waste. When bacteria from periodontal disease or infected teeth enter the bloodstream, it can damage the liver. This can create a domino effect in which other internal systems that rely on the liver’s functions become compromised as well.


When kidney function is compromised, waste products can build up in your pet’s body. Acute renal disease can develop when infection enters the bloodstream, with long-term damage including diabetes and elevated blood pressure. A dog with kidney disease can also become easily dehydrated and may have problems managing bladder and bowels.

Recognizing the Signs

The faster a dog’s tooth infection is diagnosed and treated, the less resulting organ damage is likely to take place. Pay close attention to your pet’s eating habits and look for signs such as chewing on one side of the mouth, swollen gums or loose, lost or broken teeth. Also keep an eye out for excess saliva and gum abscesses -- all of which are signals your pet may be suffering from some sort of dental ailment.

Preventative Measures

Brush your dog’s teeth using a canine toothbrush and specially-formulated toothpaste on a regular basis. If your pet struggles or you find this task difficult, ask your vet to refer you to a pet dentist, or find a reputable groomer that provides the service. Ask your vet to check your pet’s teeth during annual exams so you can be made aware of any potential dental disorders.
