I had a broken molar needing extraction, and the procedure was refused unless I stopped taking aspirin/
plavix. My GP said to stop taking the medication for three days prior the op
and then restart two days after.
My Cardiologist went bananas. He said 24 hours is all it takes to reduce the blood thinners sufficiently and it has been proved with teeth extractions, bleeding is no more in ppl on those medications than anyone else.
