There IS a caution in those detailed 'prescribing information sheets' for those meds about not taking these meds the day of the procedures? And, as a result? I've got a BIG 'NO epinepherine' note on the front of my dental file!
The descretionary use and cautious use of many anathestics for PN'ers is similar to a degree with those who have MS. MS Folks have and are the lead in the forefront about how many painkillers can make the long term pains worse.

A really Good to Great dentist and good dental care are keys to saving your teeth IF YOU CAN!
