I have heard that dentistry and veterinary are the two most depressed vocations because people generally dislike having to visit them, and patient anxiety / pain adversity leads to less positive feedback. Reddit accepts a high level of cynicism which could easily amplify negative or alarmed perceptions. ("Kill it with fire!")<p>To counter this, a lot of dentists use phrases like "pain free" in their ad collateral, and include all kinds of joyful imagery in their offices.<p>The only problem I've had with my dentist, and it is such a minor quibble that is hardly worth mentioning (except that it is on-topic), is that after every appointment they try to sign me up for wisdom tooth extraction. I'm over 50 and have never had problems with my wisdoms - even the x-rays show them as being perfectly fine. Maybe harder to reach, but they're still clean and healthy anyway. So I just say "No thanks" and schedule my next appointment.<p>I think my hygienist has an awesome personality, so I don't give her any flack for trying to bring more money into the clinic.
