When should aspirin be discontinued before a dental extraction?

Do Not Stop Aspirin Before Dental Extraction

For minor dental procedures including tooth extractions, aspirin should be continued without interruption. 1

Evidence-Based Recommendation

The most recent and authoritative guidance comes from the 2022 American College of Chest Physicians (ACCP) Clinical Practice Guideline, which explicitly recommends continuing antiplatelet drugs (including aspirin) for minor dental procedures rather than stopping them beforehand 1. This represents the highest quality guideline evidence available and directly addresses your question.

Key Supporting Evidence:

• Small randomized trials and cohort studies in patients undergoing minor dental procedures showed no increase in major bleeding with aspirin continuation 1
• The guideline notes that local hemostatic measures are sufficient to control any bleeding that occurs during dental extractions 1
• Multiple research studies confirm this approach is safe: patients on low-dose aspirin (75-100mg daily) can safely undergo dental extractions without stopping the medication 2, 3, 4, 5

Risk-Benefit Analysis

Bleeding Risk (Low):

• Studies consistently show that while bleeding time may be slightly prolonged in patients on aspirin, local hemostatic measures (pressure packs, suturing, gelatin sponges) are adequate to control bleeding 2, 3, 4, 5
• No episodes of uncontrolled postoperative bleeding have been reported in multiple studies 2, 3, 5
• Even when bleeding occurs, it is typically mild and managed within the first 30 minutes 4

Thrombotic Risk (High):

• Stopping aspirin puts patients at risk for potentially catastrophic thrombotic events including myocardial infarction, stroke, and stent thrombosis
• The thrombotic risk of discontinuation far outweighs the minimal bleeding risk from dental procedures

Special Consideration: Dual Antiplatelet Therapy

If a patient is on both aspirin and a P2Y12 inhibitor (clopidogrel, prasugrel, or ticagrelor):

• Continue the aspirin
• The P2Y12 inhibitor may be interrupted if deemed necessary 1
• This provides a balanced approach for patients requiring dual antiplatelet therapy

Common Pitfall to Avoid

Do not reflexively stop aspirin for 7-10 days before dental procedures as was historically recommended. This outdated practice:

• Unnecessarily exposes patients to thrombotic risk
• Is not supported by current evidence
• May lead to serious cardiovascular or cerebrovascular events

The French guidelines 6 do suggest a 3-day washout period for aspirin before high-bleeding-risk procedures, but they specifically note that dental extractions showed comparable bleeding complications regardless of aspirin discontinuation duration in a randomized trial of 258 patients 6. This reinforces that for dental procedures specifically, continuation is safe.

Practical Implementation

For dental extractions in patients on aspirin:

1. Continue aspirin at the current dose (typically 75-100mg daily)
2. Ensure adequate local anesthesia
3. Perform atraumatic extraction technique
4. Apply local hemostatic measures: suturing, pressure packs, gelatin sponges
5. Provide clear post-operative instructions for managing minor oozing (gauze compression)

This approach prioritizes patient safety by preventing life-threatening thrombotic events while managing the minimal and controllable bleeding risk associated with dental procedures.
