Hello from JustAnswer.
Actually, the risk that aspirin will cause bleeding after a simple tooth extraction is quite low. If a more extensive dental procedure is done, there is a greater risk, but if it is a simple tooth extraction, the risk is very low. The current recommendation for someone scheduled for a tooth extraction and taking aspirin is that the aspirin does not need to be stopped. Instead, inform the Dentist performing the procedure that you are taking the aspirin and they will use local methods to minimize the risk of bleeding.
If there is consideration that more extensive dental surgery may need to be done beyond a simple extraction, then it may be necessary to consider stopping the aspirin, but the specific approach would depend upon the clinical reason for which the aspirin is being used.
However, if it is certain that it is only a tooth extraction that is anticipated, then there is no need to stop the aspirin and you only need to inform the Dentist that you are taking the aspirin.
If I can provide any further information, please let me know.
