DH was on coumadin for 12 years. He was required to stop his coumadin 10 DAYS before extractions. He had quite a few because radiation from cancer treatment has ruined his teeth. Always stopped 10 days before and never a problem. No excessive bleeding, etc. He was also on aspirin and stopped it at the same time.
He now is off coumadin but still takes the aspirin. Had a double extraction last year and stopped his aspirin 10 days ahead. Smooth sailing.
So next time. . . check with your doctor, but he will probably suggest you stop it 10 days in advance.
