Blood coming out of your mouth
Mouth bleeding can arise from gums, a tooth socket, the tongue, cheek, or throat, and urgency depends on its amount, source, and whether it stops.
The short answer
Oral bleeding is a symptom, not a diagnosis, and the source may be superficial gum tissue, a wound, dental trauma, or a recent extraction.
Which mouth injuries or conditions can release blood?
Gingivitis, a cut, biting the cheek, a loose baby tooth, an extraction site, a broken tooth, or a bleeding lesion can release blood. Blood from coughing or vomiting may come from outside the mouth.
How should you apply gauze when your mouth is bleeding?
Sit upright and press clean gauze firmly on the site without repeatedly lifting it to check. Do not rinse forcefully after an extraction, and do not place aspirin directly on gum tissue.
When does mouth bleeding require emergency help?
Get emergency help if bleeding is heavy, continues despite sustained pressure, follows major facial injury, or is accompanied by faintness, breathing difficulty, or trouble swallowing.
What should you ask about the source of mouth bleeding?
Ask where the bleeding is coming from, whether a socket or gum needs treatment, and whether medicines or a bleeding disorder could be contributing.
Frequently asked questions
What if bleeding starts after a tooth extraction?
Place gauze over the socket and apply firm pressure as instructed; contact the dental team urgently if it does not settle.
Can gum bleeding be an emergency?
It can be when bleeding is heavy or persistent, or when swelling affects swallowing or breathing.
