I have had problems with a bad upper molar for YEARS and had gone to two different endodontists for treatment. They both did work but I still had problems.
I was finally recommended to Dr. Gutmann (yea!). He was able to determine that I had an incomplete root canal (missed by the other two endodontists). He cleaned out my infected tooth which in turn cured my raging sinus infections that I had been suffering from for years. That in turn kept me from missing work and thus saved myu job. So.... I think he is GREAT!
