Warfarin and tooth extraction bleeding
Do you have to stop warfarin before a tooth extraction? What current guidelines say about INR ranges, local bleeding control, and the real risk of stopping vs continuing.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
Quick answer
Current guidelines almost never recommend stopping warfarin for routine tooth extractions. The risk of a clot, stroke, or other thrombotic event from stopping it is generally higher than the risk of bleeding from continuing it. Most extractions can be done safely if your INR is in the therapeutic range (usually 2.0 to 3.5) on the day of the procedure, with local bleeding control measures. Coordinate with both your dentist and your prescribing physician before the appointment.
The mechanism
Why warfarin changes the bleeding picture
Warfarin blocks the production of vitamin K-dependent clotting factors in the liver. This slows the speed at which blood forms a clot, which is exactly the effect that prevents strokes and DVTs in at-risk patients. The same effect means that any procedure that breaks tissue, like a tooth extraction, will bleed for longer than it would in a patient not on the medication.
The dental concern is not whether you will bleed; you will. The concern is whether bleeding can be controlled with local measures. The answer for routine extractions, including most multi-tooth and surgical extractions, is yes. Sutures, gelfoam, oxidized cellulose, tranexamic acid mouthwash, and direct pressure are all reliable tools that work in patients on warfarin.
The reason guidelines have moved against stopping warfarin is not that bleeding has gotten less serious. It is that stopping the medication causes documented harm: stroke, pulmonary embolism, and DVT all happen at measurable rates during the days the medication is paused. The bleeding from continuing warfarin is usually manageable; the clot from stopping it sometimes is not.

Signs to watch for
When to call your dentist after an extraction
- Bleeding that does not slow down after holding firm pressure on gauze for 30 to 45 minutes.
- Active bright red bleeding the morning after the extraction.
- A large clot forming in the mouth that keeps reforming after you spit or swallow.
- Swelling that increases on day three or beyond, especially with fever.
- Sudden, severe pain that starts a few days after the extraction (this can mean dry socket).
