My sister and I were both traumatized by a sadistic dentist when we were kids.
There were red flags that our parents ignored because he, mysteriously, had an excellent reputation.
We were -- are are -- angry at our parents for not protecting us from this experience.
I would definitely encourage you to write more Idiot Dentist stories to steer readers away from these jerks.
There are TERRIFIC, competent and caring dentists out there. The more people realize this, the less likely they are to subject their kids to idiots and sadists.
