Almost always gingivitis from plaque - brush and floss properly and it usually improves in 1-2 weeks. Bleeding past two weeks, or with easy bruising and nosebleeds, needs a dentist or blood test.

Common questions
What does it mean if my gums bleed?
Bleeding gums almost always mean gingivitis - inflamed gums from plaque buildup at the gumline. The irony that keeps people stuck: gums bleed because plaque irritates them, and then people brush the sore spot less, so more plaque builds, so they bleed more. The fix is the opposite instinct - brush twice daily and floss daily, gently but thoroughly, and the bleeding typically improves within one to two weeks as the inflammation settles. MedlinePlus confirms plaque-driven gum inflammation is the leading cause. The supporting cast: a too-hard toothbrush, a new flossing routine that irritates at first, hormonal changes in pregnancy, vitamin C deficiency - rare but real in very restricted diets - and blood thinners, which make any gum irritation bleed more. When it is past the toothbrush: gums that still bleed after two weeks of good care need a dentist, because established gum disease needs professional cleaning before it quietly loosens teeth. Bleeding gums plus easy bruising, frequent nosebleeds, or unusual fatigue is the combination that warrants a blood test for platelet or clotting problems. And gums that are swollen, painful, with sores or fever suggest an infection that needs prompt dental care. Pymander is a free AI doctor, 24/7 by text.
