Causes of bleeding gum

  • Poor maintenance of the teeth, such as inadequate brushing or failure to rinse the mouth after meals results in a thin layer of food and bacteria covering the tooth surface. This bacterium is the chief culprit behind the inflammation and causes damage. The gums during the stage of infection become soft, spongy and swollen. Trauma to the gums by hard brushing or tooth picking with sharp objects result in gingival bleeding.
  • Bleeding can also be due to injury of the gums by any sharp food item e.g., fish bone.
  • Hot food and chemicals can end up burning the gums, further resulting in bleeding. For e.g. Some people still follow the practice of placing pain relieving tablets on the gum adjacent to the painful tooth, which invariably causes burns and keading to gum bleeding.
  • Certain rapidly spreading infections can damage the blood vessels of the gums resulting in bleeding.
  • Deficiency of Vitamin C causes problems with the blood vessels, hence causing bleeding in the gums.


Certain general illness of the body can also precipitate gingival bleeding

Allergic reaction.
Increase in number of cells called platelets. These are cells, which join together to form a plate that blocks thebleeding from an injured vessel.
Failure in Blood clotting mechanism due to deficiency of a few important components of clotting.
Cancerous condition called leukemia.
Certain drugs such as aspirin and anti-coagulants, which prevent the normal clotting mechanism of the blood.
Bleeding of the gums may occur with or without associated pain .The pain if present is usually dull in nature.
