Whether or not you can extract a tooth three days after stopping aspirin needs to be analyzed on a case-by-case basis. Different patients have different conditions and different severities, so you need to balance the pros and cons to determine. 1. Patients who have been taking aspirin for a long time, if in small doses, can stop taking the drug before extraction, considering that the risk of stopping the drug is more harmful than bleeding after extraction. If you need to stop the drug should start 3~5 days before the operation, after the operation also need to be placed in the extraction wound in the electric discharge sponge and other antiemetic drugs, and closely observed for 30 minutes, no active bleeding before leaving. 2. However, if the long-term high dose of aspirin patients, and must be extracted depending on the patient’s specific circumstances, generally at least 3 days after the drug can be extracted. 3. Aspirin belongs to the antiplatelet drugs, it is easy to lead to tooth extraction wound does not heal or even the possibility of continuous bleeding. Therefore, before tooth extraction, we should pay special attention to whether the patient has taken aspirin drugs. Please consult your doctor if you have any discomfort.
