Can I get a dental implant if I take Coumadin?

Coumadin is an anticoagulant (blood thinner), which reduces the formation of blood clots. It does so by blocking the synthesis of certain clotting factors. A reduction in clotting factors will also reduce the chance of any blood clot formation.

Coumadin is predominantly used to prevent heart attacks, strokes and blood clots in veins and arteries as well as around prosthetic devices, such as artificial heart valves. The down side of Coumadin are the prolonged bleeding times. This is of great concern to anyone who needs to undergo minor surgery.
Many patients who take Coumadin get their INR (International Normalized Ratio) and PT (Prothrombin Time) tested on a regular basis. The Prothrombin time (PT) evaluates the ability of blood to clot properly, whereas the International Normalized Ratio (INR) is used to monitor the effectiveness of blood thinning drugs such as Coumadin (or also Jantoven, Marevan and Waran, which are all brand names for the generic Warfarin).

Most dental surgeons will look for the INR assessed a day prior to surgery, to determine whether it is safe to perform any minor oral surgical procedure, however some also consider the PT time along with the INR. Your cardiologist is always the final decision maker, however. Sometimes they will take you off the Coumadin and switch you over to Heparin a few days prior and after the surgery, sometimes they may just take you off for a couple of days. This will really depend on how high your risk of clot formation is and only your cardiologist can make this decision.

So to answer the original title question: As long as you are carefully monitored and prepared by your cardiologist just prior and after the dental implant surgery, you can get dental implants. There are no published studies showing an decrease in success rates of dental implants in patients taking any of the Warfarins.
