I like your mantra!
Dental health is extremely important,however,some will perform unnecessary work.2 years ago,I decided to switch dentist because she found a cavity (there was none) On the first visit,he wanted to extract 3 teeth!I have all my teeth and had no pain. I think I found a solution,I choose a dentist who is part of a major hospital.He/she is less likely to perform work not required. I can not believe that those who are supposed to be held to a higher standard would be unethical.
In urban areas where birth rate is low,more Caesarean section is performed! Google it.
