I need some advice. My Dentist told me that I need a dental implant. I have an ON-X heart valve and am on warfarin. The Dentist wants me to go off the warfarin 2 to 3 days prior to my dental implant appointments. My Cardiologist says that he will go along with what the Dentist recommends. I am leary about going off the warfarin. Studies that I have read seem to suggest that the risk of a blood clot while off warfarin exceeds the bleeding risk while taking warfarin during dental implant procedures. Has anyone had any expierence with dental implants while on warfarin.
