Why do dentists get less respect than doctors? This leads to another question: why is it that when i'm at the dentist, they are taking care of my health but also "selling" me on every service i "need"? I wonder if they were paid more, or if there was better dental insurance out there, would there be as much second -guessing of their credibility.
