Q) Should I stop my blood thinner prior to my dental procedure?

A) Patients on warfarin or other blood thinners such as Plavix, Aspirin and Pradax are at an increased risk of suffering bleeding complications from dental procedures. But stopping those drugs can put the patient at an increased risk of a blood clot and
subsequent stroke or heart attack. 

Experts have weighed the relative merits of these two
risks and have concluded that in the vast majority of cases, these drugs should not be stopped as the risk of a clot is much higher than the risk of a major bleed.

As long as the INR (a measure of how thin the blood is) is less than four, these drugs should be continued during most procedures including crowns, bridges, root canals, implants, gingival surgery, supra gingival scaling and the simple extraction of a limited number of teeth. 

Patients taking combinations of blood thinners together are at a higher risk of bleeding and should be managed by a dentist or oral surgeon familiar with them. 

Precautions include: checking the INR at 72 hours prior to the appointment if the INR has been stable (24 hours prior if it has not been), and scheduling the appointment both early in the day and early in the week to ensure access to health professionals should complications arise. 

 

After the procedure, patients should avoid activities that could provoke bleeding such as chewing hard foods, vigorous rinsing, consuming hot foods/liquids or sucking using a straw or cigarette. 

If the wound starts to bleed, bite down on a gauze pad or slightly moist tea bag for 20 minutes, and call the
dentist if it doesn't stop bleeding.
