Bleeding gums is a common symptom of the periodontal diseases, or gum diseases, such as gingivitis and periodontitis. Periodontal disease is a serious bacterial infection that destroys the gums and the surrounding tissues of the mouth. If the inflammation is left untreated, the disease will continue and the underlying bones around the teeth will dissolve and will no longer be able to hold the teeth in place.
Bleeding gums are mainly caused by inadequate plaque removal from the teeth at the gum line which can lead to gingivitis and eventually periodontitis.
Other causes of bleeding gums include:
- Bleeding disorders
- Brushing too hard
- Hormonal changes during pregnancy
- Idiopathic thrombocytopenic purpura
- Ill-fitting dentures
- Improper flossing
- Infection (either tooth or gum-related)
- Use of blood thinners
- Vitamin K deficiency
