About the Symptom

Bleeding gums are a sign of gingivitis, or inflammation of your gums. It is common and a mild form of gum disease, and is usually caused by a buildup of plaque at your gum line. It could also be due to brushing too hard, medications, underlying medical conditions like bleeding disorders or vitamin deficiencies.

Possible Causes

Generally, Bleeding gums when brushing can be related to:

  • Dental Caries

    Dental caries occur when the hard outer layer of your tooth, the enamel, gets destroyed, sometimes forming small holes or cavitations. Common causes include eating and drinking sugary foods, frequent snacking, dry mouth and poor oral hygiene.

  • von Willebrand Disease (vWD)

    von Willebrand disease (vWD) is a common genetic blood disorder that impairs blood clotting leading to excess bleeding. In people with vWD, a protein called von Willebrand factor that is critical to blood clotting either does not function properly or is insufficient. As a result, people with vWD bleed more easily.

  • Acquired Hemophilia

    Acquired hemophilia is a rare autoimmune disorder causing bleeding tendencies due to the development of antibodies against clotting factors.

  • Congenital Hemophilia
