Anticoagulant management for dental procedures

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: 5% solution 5 mL hold in mouth × 2 min then spit, 4× daily for 2 days post-procedure
Paediatric: —

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

Adult: 1–2.5 mg PO or 1 mg IV slow for partial reversal; 5–10 mg IV for full reversal in life-threatening bleeding
Paediatric: 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

Adult: 5 g IV (2 × 2.5 g) over 5–10 min
Paediatric: —

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

Adult: Andexanet alfa 400/800 mg IV bolus; PCC 50 IU/kg IV
Paediatric: —

Major bleeding requiring hospital admission; high cost; specialist setting; not routine in dental practice

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]

Clinical summary

Risk-balanced peri-procedural anticoagulant management for adults undergoing dental and oral surgery procedures.
