Alcohol is not recommended before or after tooth extraction. 1. Drinking before tooth extraction will lead to the presence of the body containing a certain concentration of alcohol, affecting the effect of anesthesia. Drinking after tooth extraction will lead to accelerated blood circulation, which will easily cause bleeding from the wound. 2. In addition, as tooth extraction is an invasive operation, oral antibiotics are usually required, mostly cephalosporin antibiotics and nitroimidazole antibiotics, and most types of these two drugs carry the risk of disulfiram reaction. Therefore alcohol is not recommended before or after tooth extraction. Avoid fasting before tooth extraction and avoid physiological periods for women. On the day of tooth extraction, it is recommended to eat a light diet, do not exercise strenuously, do not brush your teeth that night, and it is also recommended to go to the dentistry department of a regular hospital for timely consultation if there is any discomfort such as secondary bleeding.
