Bill, I am surprised to hear that you were not informed about the importance of getting the ok from a dentist prior to treatment.Ihad 6 weeks between diagnosis and treatment, and in that time saw many doctors. The most asked question was have you been to the dentist? No? Then get there ASAP. I do not believe it was your duty to figure that one out. I would never have thought to get a dental eval. on my own. The dentist scares me!
