Bleeding gums can be a sign that you have or are at risk for gum disease. Ongoing gum bleeding may be due to serious medical conditions such as leukemia and bleeding and platelet disorders.
The main cause of bleeding gum is the buildup of plaque at the gum line. This will lead to a condition called gingivitis, or inflamed gums.
Plaque that is not removed will harden into tartar. This will lead to increased bleeding and a more advanced form of gum and jawbone disease known as periodontitis.
Other causes of bleeding gums include:
- Any bleeding disorder
- Brushing too hard
- Hormonal changes during pregnancy
- Idiopathic thrombocytopenic purpura
- Ill-fitting dentures or other dental appliances
- Improper flossing
- Infection, which can be either tooth- or gum-related
- Use of blood thinners
- Vitamin K deficiency
