Management of Anticoagulation for Dental Procedures

Introduction to Anticoagulation Management

The American College of Cardiology recommends that blood thinners should not be discontinued for tooth extractions, as the risk of thromboembolism from discontinuation outweighs the minimal bleeding risk that can be effectively managed with local hemostatic measures 1
The American College of Cardiology notes that discontinuing anticoagulants increases the risk of serious thromboembolic complications, particularly in patients with mechanical heart valves, recent coronary stents, or high CHADS2 scores 1

The American College of Chest Physicians recommends continuing warfarin therapy without interruption for dental extractions 2
Local hemostatic measures, such as absorbable gelatin sponge placement and suturing of the extraction site, can be used to control bleeding 1
Tranexamic acid mouthwash (5 mL, 5% solution) can be used before the procedure and 2-3 times daily for 1-2 days after to control bleeding 2, 3
Continue ASA without interruption for all procedures, as maximal antiplatelet effect occurs within minutes of administration 2
Continue clopidogrel without interruption for minor procedures; note that if clopidogrel had been interrupted, it takes 5-10 days to attain maximal platelet function inhibition at a maintenance dose of 75 mg/day 2

Patients with multiple tooth extractions or poor gingival health may require additional local hemostatic measures, but anticoagulation should still be continued 3, 4
Patients with mechanical heart valves, recent coronary stent placement, recent thromboembolism, or atrial fibrillation with high CHADS2 score have higher thrombotic risk and should not discontinue anticoagulation, as recommended by the American College of Cardiology and supported by Circulation and Stroke 5, 6, 7, 8
Patients on dual antiplatelet therapy (DAPT) or triple therapy have higher bleeding risk, and consideration should be given to discussing with a cardiologist or modifying the regimen 9, 1, 2
Patients on ticagrelor (Brilinta) following cardiac stent placement should not discontinue their medication before procedures, as the risk of stent thrombosis far outweighs the minimal bleeding risk that can be effectively managed with local hemostatic measures, according to the European Society of Cardiology guidelines 10

Post-procedure care should include instructions on managing minor bleeding and avoiding NSAIDs for pain management, and common pitfalls to avoid include routine discontinuation of antiplatelet therapy, failing to distinguish between antiplatelet agents and anticoagulants, and recommending NSAIDs for post-procedure pain in patients taking aspirin 1, 9, 11, 3
Local hemostatic measures such as absorbable gelatin sponge, suturing, local pressure application, and tranexamic acid mouthwash can effectively control bleeding during procedures in patients on antiplatelet therapy, with a low risk of significant bleeding 11, 3, 4
Consultation with a cardiologist is recommended before any changes to antiplatelet therapy, especially for extensive procedures, and for patients with high-risk factors for stent thrombosis, as emphasized by the American College of Cardiology and the American Heart Association 12, 9, 1, 2

Warfarin should be continued without interruption, with INR within therapeutic range (2.0-3.0), as recommended by the American College of Cardiology 5, 7, 8
The American College of Chest Physicians recommends continuing antiplatelet therapy throughout procedures without interruption, as the risk of thrombotic events from discontinuation far outweighs the minimal bleeding risk that can be effectively managed with local hemostatic measures 3
Patients should inform their healthcare provider about their anticoagulation status, and the healthcare provider should use appropriate techniques to minimize trauma and be prepared for potentially increased bleeding 9, 1, 2
Patients should monitor for excessive bleeding after the procedure and seek medical attention if bleeding cannot be controlled with local measures 11, 3, 4
