Bleeding out mouth

Mouth bleeding can come from injured tissue, gum inflammation, a tooth socket, or a medical problem, and heavy bleeding needs urgent care.

Blood may come from gums, the tongue, cheek, lips, a recent extraction site, or a damaged tooth. Plaque-related gingivitis commonly causes bleeding during brushing, while trauma, infection, medicines, or clotting problems can produce other patterns.

Sit upright, place clean gauze or cloth directly over the area, and apply steady pressure without repeatedly checking it. Do not scrub the wound, spit forcefully, or place aspirin directly on the gum; follow extraction instructions if a tooth was removed.

Seek emergency medical care if bleeding is heavy, does not slow with firm pressure, follows a serious injury, or occurs with weakness, breathing difficulty, facial swelling, or trouble swallowing. Arrange dental care for repeated gum bleeding or bleeding after extraction.

Tell the dentist where the blood began, how long it lasted, whether it follows brushing or surgery, and which medicines you take. Ask whether the cause is gum disease, a local wound, infection, or a problem needing medical evaluation.
