Bleeding after tooth extraction in patients receiving anticoagulation/antiplatelet therapy

Tooth extraction in patients receiving anticoagulation/antiplatelet therapy is often considered contraindicated by many oral and maxillofacial surgeons because of a higher risk of postoperative bleeding. Multiple factors contribute to postoperative bleeding, but there is no consensus. Based on recent literature, this article reviews factors related to bleeding after tooth extraction in patients receiving anticoagulation/antiplatelet therapy. The literature review indicates that patients taking antiplatelet drugs have a lower postoperative bleeding risk than patients taking anticoagulant drugs. Prescription of anticoagulants together with non-steroidal anti-inflammatory drugs, selective serotonin inhibitors or serotonin-norepinephrine inhibitors increases the risk of bleeding, so does preoperative antibiotic use increase. In addition, systemic diseases such as diabetes, history of infection at the extraction site, and greater surgical trauma are associated with a higher risk of postoperative bleeding. At present, it is generally believed that it is safe and feasible to use different hemostatic measures after tooth extraction and to rationally apply different hemostatic measures after surgery. More prospective controlled trials are needed in the future to establish an assessment system for patients undergoing anticoagulation/antiplatelet therapy under different conditions during tooth extraction.
