Health

The overall health of a dog or human can affect the bacteria in their mouths. This is because the bacteria in the mouth are part of the body’s microbiome, which is a complex community of trillions of bacteria that live in and on the human body. The microbiome plays a vital role in human health by helping to digest food, fight off infections, and regulate the immune system.

When a dog or human is healthy, the microbiome is in balance and the bacteria in the mouth are kept in check. However, when a dog or human is sick or has poor oral hygiene, the microbiome can become imbalanced and harmful bacteria can start to grow.

Poor oral hygiene is a major cause of harmful bacteria in the mouth. When a dog or human does not brush their teeth regularly, plaque and tartar can build up on the teeth. Plaque is a sticky film of bacteria that forms on the teeth, and tartar is a hard mineral deposit that forms when plaque is not removed. Plaque and tartar can irritate the gums and cause them to become inflamed. This inflammation can lead to periodontal disease, which is a serious infection of the gums and supporting structures of the teeth.

Periodontal disease is a major cause of tooth loss in dogs and humans. It can also lead to other health problems, such as heart disease, stroke, and diabetes.
