Drinking alcohol may interfere with the action and metabolism of anesthesia drugs, so it is not recommended to drink alcohol the day before tooth extraction. 1. When extracting teeth, local anesthesia medication is usually needed. Drinking alcohol the day before may cause adverse reactions due to the residual alcohol and its metabolites in the blood, which may react with the anesthesia medication locally; in addition, since part of anesthesia medication is metabolized by the liver, which is the same metabolism site as that of alcohol, drinking the day before may interfere with the medication’s metabolism, and therefore drinking alcohol is not recommended. 2. In addition, alcohol has a certain effect on the normal healing of wounds. Before and after tooth extraction, it is recommended to have a light diet and avoid spicy and stimulating foods; it is also recommended to avoid smoking and drinking, ensure sufficient rest and relax. In daily life, it is recommended to stop smoking and limit alcohol consumption, and maintain good living habits.
