I have never written a review online before but felt strongly enough to let Tucsonans know that Dr. John Smith is the best endodontist in town. I just had my second root canal with Dr. Smith in January 2012. Of course no one wants to have this procedure but if you need one I can tell you this is the best place to go. Dr. Smith is very professional, communicative, a good listener and caring. The best part is his expertise in his field as both of my procedures went so smoothly. Each time I filled the prescription for pain meds, for post op pain, and neither time did I take any. Finding a good dentist in Tucson is challenging and that is why I felt compelled to write this. Dr. Smith's entire staff is experienced, competent and kind.
