Paranoia is unbased fear. I think this poster has a good basis for fear. Dentist do lots of damage. Look at the root canals they do to people. Look at the mercury fillings. Look at how they do not take out the periodontal ligament and they do not clean out the hole that is left after an extraction either. I do not think that dentists are unaware at all. I think they know exactly what they are doing. The sad part is that they do not care.
