Dental Work on Warfarin: A common question from patients and dentists is whether warfarin needs to be interrupted at times of dental procedures, such as cleaning or pulling of teeth or root canals. Medical publications and recommendations from the dental community outlining best management of patients on warfarin exist (ref 1-6). However, even though evidence suggests that stopping warfarin for low-risk dental procedures is not necessary, many dentists are hesitant to perform dental procedures if the patient is on warfarin.
Communication between the health care provider dealing with the patients warfarin management and the dentist is important to make a solid decision whether warfarin needs to be discontinued or not. This table (blog#3 table) (from ref 4) can be helpful in the communication process.
My Conclusions
The study confirms what has been observed over the last few years: that many dental procedures can be safely done on warfarin. Warfarin interruption for dental cleaning, pulling of one or several teeth, or root canals is typically not needed. However, good local measures by the dentist (such as fibrin sponges, silk sutures and gauzes saturated with tranexamic acid) to minimize bleeding risk are prudent.

I talked to my dentist about cleanings and bondings while on Pradaxa. He didn't seem to think it was an issue. He just wanted to know to be extra careful.

Just returned from a cleaning at the dentist. He said no need to stop blood thinners (I'm on Xarelto) for a cleaning or filling, but probably so for an extraction.
