I am a dentist. I have referred many patients to him in the past. Suddenly it was my turn. An old bridge failed, and the molar abscessed. Dr. Janse did a 10+ job on it ... you would expect an endodontist to do that ... but this was a very difficult root canal to fill. It was full of calcium and another dentist had been unable to find the third canal. Dr. Janse found it with his very special, very expensive operating microscope. Even then, it was difficult. I would rate it a 10 out of 10 on difficulty. I am totally pain free now, and looking forward to getting a new bridge done. Thanks a lot Scott!!! Also I should say that my patients are always happy with him. My only complaint ... his office is an hour drive from mine. Robert E. Carpenter,DDS, Kerrville Texas
