Black blood in mouth in morning
Dark material in morning saliva can be older blood mixed with saliva, but repeated bleeding needs an examination of the gums, nose, throat, and mouth.
The short answer
Dark blood usually means blood has remained in the mouth long enough to change colour or has mixed with saliva and debris.
What is the direct answer?
What does this question mean?
Possible dental sources include inflamed gingiva, plaque or calculus around a back tooth, a bitten cheek, a loose restoration, or a healing extraction site. A clinician may inspect the gum margins, periodontal pockets, tongue, palate, and nearby teeth, while also considering a nose or throat source.
What can you do next?
Rinse gently with water, brush softly with a fluoride toothpaste, and note where the blood appears, how often it occurs, and whether there is pain, swelling, bad taste, or nasal bleeding. Avoid smoking and vigorous rinsing around a healing wound.
When should you seek dental care?
Arrange dental care if the finding recurs, the gums bleed during cleaning, or there is swelling, pain, a loose tooth, or a wound that does not heal. Seek urgent help if bleeding is heavy or will not stop with gentle pressure.
What should you ask the dentist?
Ask whether the blood is coming from gum inflammation, a socket, a tooth, or another part of the upper airway, and whether an examination, periodontal chart, or radiograph is needed.
