The most common cause of bleeding gums is plaque buildup along the gumline, which irritates and inflames the gums — a condition called gingivitis. It often shows up when brushing or flossing.
Other factors can contribute, including infrequent flossing, a new flossing routine, certain medications, hormonal changes, or vitamin deficiencies. Persistent bleeding warrants a dental visit.
Professional cleaning removes the plaque and tartar that home care can't, and your dentist can advise on a home-care routine to keep your gums healthy between visits.
Frequently Asked Questions
Should I stop flossing if my gums bleed?
