Gingivitis: Gingivitis is the most common cause of bleeding gums. It is a mild form of gum disease characterized by inflammation of the gums due to the accumulation of plaque (a sticky film of bacteria) on teeth. The gums become red, swollen, and may bleed when brushed or flossed.
Poor Dental Hygiene: Inadequate brushing and flossing can lead to the buildup of plaque and tartar, which irritate the gums and cause them to bleed.
Periodontitis: If gingivitis is left untreated, it can progress into a more severe form of gum disease called periodontitis. This condition involves the inflammation and infection of the supporting structures of the teeth, including the bone. Bleeding gums are a common symptom of periodontitis.
Medical Conditions: Certain medical conditions and medications can increase the risk of bleeding gums. These include blood disorders, vitamin deficiencies (especially vitamin C and K), and some medications like anticoagulants (blood thinners).
Hormonal Changes: Hormonal changes, such as those during pregnancy, menstruation, or menopause, can make gums more susceptible to bleeding.
