Generally speaking, tooth extraction can be performed in the morning or in the afternoon for healthy people, with no specific time limit. However, if there is enough time, it is usually recommended to have the tooth extracted in the morning to allow enough time for observation, so that if abnormal bleeding, pain and other uncomfortable symptoms occur, it will be easier to go to the hospital for timely treatment. Besides, since the affected area needs some time to clot after extraction, if the tooth is extracted in the afternoon, there may still be incomplete clotting when you sleep at night. Moreover, if the sleeping position changes during sleep, the affected area may be squeezed to a certain extent, which may easily cause bleeding. Therefore, it is generally recommended to choose the morning as the time for tooth extraction. However, if the tooth is extracted in the afternoon, there is no need to worry too much. After the extraction, strictly follow the doctor’s instructions, do a good job of stopping the bleeding, and contact the doctor or seek medical attention in case of discomfort. It should be noted that if a woman has a tooth extraction, she should try to avoid having the tooth extracted during menstruation, pre-pregnancy and pre-breastfeeding period, as the risk of extraction is higher at this time. Patients with systemic diseases such as heart disease, severe hypertension, anemia, diabetes, chronic kidney disease, or those in the acute phase of inflammation should also follow medical advice to delay or avoid tooth extraction. In addition, if you are taking anticoagulant drugs such as aspirin, dabigatrans, or long-term treatment with adrenocorticotropic hormones, you should also avoid tooth extraction while taking the drugs.
