A careful history may reveal that the patient inadvertently caused the extraction site to bleed by drinking through a straw, spitting, gargling, or smoking. All these activities will produce negative pressure within the oral cavity and remove the clot from the extraction site. Ask the patient if they are touching the extraction site with their tongue, causing a mechanical disruption of the clot. Obtain information about any significant medical history, any history of bleeding, and current medications. This includes use of aspirin products, anticoagulants, broad-spectrum antibiotics, alcohol, and antineoplastic medications. These all may contribute to prolonged bleeding. Ask about the symptoms and examine for the signs of liver disease, hypertension, or hematologic disorders.1,2 Post-extraction bleeding may be a sign of an underlying and undiagnosed coagulopathy.
