Alcohol is generally not allowed until about seven days after a tooth extraction, and drinking alcohol immediately after an extraction may lead to neglecting post-extraction complications and the inability to take anti-inflammatory medications, as described below. 1. Neglecting post-extraction complications: common complications include post-extraction reactive pain, postoperative difficulty in opening, post-extraction bleeding, postoperative infection, dry socket, subcutaneous emphysema, etc. Consumption of alcohol will lead to loss of self-control, confusion and other symptoms of intoxication, neglecting postoperative complications and missing the best time for treatment. 2. Inability to take anti-inflammatory drugs: Inflammatory infections may occur after tooth extraction, and anti-inflammatory drugs such as metronidazole need to be taken for prevention or treatment. Alcohol will have a disulfiram reaction with metronidazole, which can lead to mental fog, breathing difficulties, and in severe cases, anaphylactic shock. Medications should be used under medical supervision. If you experience any of these symptoms, it is recommended that you visit a hospital promptly.
