Dr Keim is a wonderful dentist. Very caring and concerned. He is a bit conservative which can be a good thing as he doesn't push the patient into alot of procedures that may not be needed, however sometimes he is a bit too conservative in his care meaning that one can spend too much time in pain without addressing the root cause. He is very available to the patient. In terms of root canals, he did a pain free procedure but broke a file in one of the canals of my tooth. Next time I'll plan on going to an endo. I went to a endo last time and did not have a problem.
