Red Flags
- Active bleeding from oral cavity refractory to local measures (pressure, tranexamic acid mouthwash, sutures, gelatin sponge) — same-day OMFS and consider anticoagulant temporary reversal[1]
- Recent thromboembolic event (DVT, PE, stroke <3 months) or recent stent — defer non-urgent dental procedures; coordinate with prescriber if procedure essential[1]
- Mechanical heart valve on warfarin — never stop without bridging plan; close coordination with cardiology[1]
- Significant DOAC overdose or accumulation in CKD — assess bleeding risk specifically; consider deferring until levels normalise[1]
First-line treatment
Interventions
- Continue anticoagulation for most low-risk dental procedures[1]Single tooth extraction, minor periodontal surgery, simple restorative — continue anticoagulant; use local haemostatic measures (sutures, gelatin sponge, oxidised cellulose, tranexamic acid mouthwash 5 mL × 4–6 daily)
- Selective DOAC dose modification[1]Higher bleeding risk procedures (multiple extractions, complex surgery): consider skipping morning DOAC dose only, perform procedure later in day, resume next dose if haemostasis achieved. Avoid bridging for DOAC
- Warfarin-treated patients[1]Continue with INR <4.0 (target therapeutic range); local haemostatic measures; avoid 'bridging' with LMWH unless mechanical valve, recent VTE, or other very high-risk indication. INR 24–72 h before procedure
- Antiplatelet management[1]Continue aspirin and clopidogrel for most dental procedures; do not stop dual antiplatelet therapy in first 6 months post-stent or 1 month post-bare-metal stent without cardiology agreement
- Local haemostasis as cornerstone[1]Atraumatic extraction technique, sutures, oxidised cellulose, gelatin sponge, microfibrillar collagen, tranexamic acid 5% mouthwash 4–6× daily for 2 days; cold compress; bite on gauze 30 min
First-line drug therapy
| Drug | Class | Adult | Paediatric | Notes |
|---|---|---|---|---|
| Tranexamic acid mouthwash[1] | Antifibrinolytic (topical) | 5% solution 5 mL hold in mouth × 2 min then spit, 4× daily for 2 days post-procedure | — | Reduces post-operative bleeding in anticoagulated patients; minimal systemic absorption; often combined with sutures and gelatin sponge |
| Vitamin K (warfarin reversal in dental haemorrhage)[1] | Vitamin | 1–2.5 mg PO or 1 mg IV slow for partial reversal; 5–10 mg IV for full reversal in life-threatening bleeding | 0.03 mg/kg IV | Rare in dental practice — most dental bleeding is controllable with local measures; reversal indicated only for major haemorrhage; recheck INR at 24 h |
| Idarucizumab (dabigatran reversal — major bleeding)[1] | Anti-dabigatran monoclonal antibody fragment | 5 g IV (2 × 2.5 g) over 5–10 min | — | Specific reversal for dabigatran-related major bleeding requiring hospital admission; not used routinely in dental practice |
| Andexanet alfa or 4F-PCC (apixaban/rivaroxaban reversal)[1] | Recombinant factor Xa decoy / prothrombin complex concentrate | Andexanet alfa 400/800 mg IV bolus; PCC 50 IU/kg IV | — | Major bleeding requiring hospital admission; high cost; specialist setting; not routine in dental practice |
Tranexamic acid mouthwash[1]
Antifibrinolytic (topical)
- Adult

Safety-net
- Continue anticoagulation as prescribed unless your clinician specifically advises otherwise — interrupting therapy usually carries higher risk than dental bleeding[1]
- Bite firmly on gauze for 30 min after extraction; use saltwater rinse from day 2; avoid hot food, alcohol, smoking, and vigorous exercise for 24 h[1]
- Persistent bleeding after 30 min of pressure, large clot, swelling, or fever — same-day OMFS or emergency department review[1]
Referral criteria
- Mechanical valve, recent thromboembolism (<3 months), recent stent, or complex anticoagulation regimensJoint decision making with cardiology and OMFS pre-procedure[1]
- Major dental surgery (multiple extractions, advanced periodontal, implant) on anticoagulationOMFS in hospital setting with optimal haemostatic measures[1]
- Active bleeding refractory to local measuresOMFS / emergency department same-day[1]
- Suspected drug interaction or supra-therapeutic anticoagulation pre-procedureAnticoagulation clinic for review[1]
