This type of bleeding starts 2 to 3 hours after tooth extraction, as a result of cessation of vasoconstriction. Systemic intervention might be required. 3. Secondary bleeding.

Root fracture of the tooth is a dentine cementum fracture involving the pulp. Traumatic root fracture occurs most often in the middle third of the roots of fully erupted and fully formed teeth.
