You should not take warfarin for tooth extraction. Tooth extraction is a kind of minor surgery, there will be bleeding, after the extraction of teeth in order to make the bleeding stop quickly, so this time you can not eat anticoagulants or blood-activating drugs, such as warfarin or panax ginseng and other drugs. If you eat such drugs will make the wound bleeding after tooth extraction, can not form a blood clot, the tooth bone wall will be exposed in the mouth, easy to be infected by bacteria to form a “dry socket”. It will also increase the patient’s fear, and the patient will feel worried and scared, or because of the heavy bleeding, the patient will experience generalized discomfort. If a patient wants to have a tooth extracted, he/she needs to consult with the doctor if it is possible to stop using Favalin before having the tooth extracted.
