Why do my gums bleed all of a sudden

Sudden gum bleeding often comes from plaque-related inflammation, but trauma, medicines, illness, or a deeper gum problem can also contribute.

Plaque is a sticky film of bacteria that irritates the gingiva, the gum tissue around each tooth. New flossing, vigorous brushing, a cut, hormonal changes, blood-thinning medicine, or conditions affecting blood cells can also make bleeding appear abruptly.

Brush twice daily with a soft-bristled brush and fluoride toothpaste, using small movements at the gumline, and clean between teeth gently with floss or interdental brushes. Rinse with water after meals, avoid picking at the gums, and note where, when, and how much bleeding occurs.

Arrange a dental examination if bleeding continues after several days of careful cleaning, recurs, or comes with swollen gums, bad breath, loose teeth, or pus. Seek urgent medical help for bleeding that will not stop, widespread bruising, faintness, facial swelling, fever, or trouble breathing or swallowing.

Ask whether the bleeding is from gingivitis, periodontitis, an injury, or another medical cause, and whether a professional cleaning or gum measurements are needed. Tell the dentist about new medicines, pregnancy, recent illness, and any bleeding or bruising elsewhere.
