Blood coming from teeth

Blood near a tooth usually comes from inflamed gum tissue, trauma, a loose tooth, or a dental infection rather than from the hard tooth itself.

Plaque can inflame gingiva, while vigorous brushing, floss injury, a sharp filling, a cracked tooth, or an abscess can cause localized bleeding. Bleeding can also follow an injury or occur more readily with some medicines or medical conditions.

Apply gentle pressure with clean gauze, rinse carefully, and avoid repeatedly probing the area. A dentist may inspect the gum pocket, tooth, bite, restoration, and nearby tissues, then use radiographs or drainage when indicated.

Get urgent help for uncontrolled bleeding, facial swelling, fever, severe pain, a knocked-out tooth, or difficulty breathing or swallowing. Book an examination when bleeding recurs, appears without brushing, or comes from one specific tooth.

Ask exactly where the blood is coming from and whether the tooth, gum, filling, or root needs treatment. Ask whether a cleaning, restoration, periodontal treatment, or urgent procedure is needed.
