What causes bleeding gums?
Bleeding gums most commonly result from inadequate plaque removal from the teeth at the gum line, resulting in a condition called gingivitis, or inflamed gums. Infection of the gum line is a common cause of bleeding gums. If plaque is not removed it will harden into what is called tartar, resulting in increased bleeding and potentially a more advanced form of gum and jawbone disease known as periodontitis.
Conditions that can cause bleeding gums include certain vitamin deficiencies, including vitamin K deficiency and vitamin C deficiency, which causes scurvy. Other bleeding disorders, such as hemophilia, leukemia, and idiopathic thrombocytopenic purpura, can cause bleeding gums. The use of medications, such as blood thinners and chemotherapy agents, can also cause bleeding gums as a side effect.
Gum disease causes of bleeding gums
Bleeding gums may be caused by gum disease including:
- Gingivitis (infection of the gums)

- When did the gum bleeding start?
