Blood inside tooth
Blood-coloured material inside a tooth can follow trauma, decay, or pulp inflammation and needs examination to identify the source.
The short answer
Blood inside or emerging from a tooth usually means the dental pulp, the living tissue containing nerves and blood vessels, has been exposed or inflamed by decay, a crack, or trauma. A dentist uses examination, vitality tests, and dental imaging to determine whether the pulp can recover or needs treatment.

Where is the dental pulp located inside the tooth?
The pulp lies inside the dentine in the pulp chamber and root canals. Deep decay, a fracture, or an impact can open a path to it; inflamed pulp may cause lingering heat or cold pain, while dead or infected pulp may cause discoloration or an abscess.
What should you do when a tooth appears to bleed?
Rinse gently, avoid chewing on the tooth, and do not place aspirin or household chemicals on the gum. If a piece broke off, keep it clean and bring it to the appointment; use only pain medicine suitable for your health history.
When does bleeding from a tooth need urgent care?
Arrange urgent dental assessment for visible pulp, spontaneous pain, swelling, a darkening tooth, pain on biting, or bleeding from a cavity or crack. Facial swelling with fever or breathing or swallowing difficulty requires emergency help.
What should you ask about the tooth pulp and its tests?
Ask whether the pulp is exposed, inflamed, or infected and what the tests show. Ask whether treatment is a protective restoration, root canal treatment, or extraction, and how the tooth will be sealed and restored afterward.
Frequently asked questions
Can a tooth bleed after an injury?
Yes. Trauma can expose or damage the pulp, so the tooth needs examination even if pain settles.
Does a dark tooth always need extraction?
No. The cause and the condition of the root and surrounding bone determine whether it can be treated and restored.
