There are very few adults with non-bleeding gums: according to statistics, 90% of the adult population has gum bleeding problems in at least a small area and at least 20% suffer from severe periodontal disease, including bone destruction and tooth decay.
Bleeding gums is a sign that the oral hygiene of a human is not 100 percent in order. This may indicate that bacteria have settled somewhere and the body is resisting it with inflammation. In these cases, the blood vessels dilate the white blood cells penetrate into the gums and protect the body from pathogens. If oral hygiene is inadequate, so-called gingivitis develops.
