Swollen and bleeding gums are themselves a common symptom of certain diseases, and if ignored, they may lead to a gradual worsening of the underlying disease and may even lead to the spread of infection. The symptom itself may also trigger the development of certain diseases, such as altered tissue structure when gums are swollen and painful, which is more likely to lead to gum damage when subjected to external impact. Bleeding can easily lead to microbial infestation and induce inflammatory lesions.
