What INR value range is considered appropriate for safe performance of dental procedures in a patient on warfarin?

An INR of 2.0–3.0 is the standard therapeutic range for most patients on warfarin and is also considered safe for routine dental procedures (simple extractions, restorations, periodontal procedures). Current evidence-based guidelines support continuing warfarin therapy without modification for most dental procedures when the INR is within the therapeutic range (up to 3.5 per some guidelines). Stopping warfarin before dental procedures is discouraged due to the thromboembolic risk. Local hemostatic measures (pressure, oxidized cellulose, suturing) should be employed.
