Some years ago I was seeing a dentist that I had no complaints about--I try to take good care of my teeth, and she would tell me what I was used to hearing, teeth look great, nothing concerning, and so on. Then one day I go to my 6 month cleaning appointment and something is off. The name of the practice is the same, my dentist's name is still on the door, but I don't recognize anyone on the staff. When I'm greeted by the hygienist (who I've also never seen before), she says I'll need x-rays taken, even though I had them taken the previous appointment, because their computers crashed and they lost all their old ones. Um. Ok. Then after my cleaning, a _new_ dentist I've never seen before comes in to check my teeth. I can't remember what excuse he gave for why the previous dentist (whose name was still on the door, I remind you) wasn't there, but it was something hand wavy. Anyway, surprise, surprise, it turns out I needed several thousand dollars of dental work done, also it's apparent that I grind my teeth and need a night guard to prevent further damage, all my enamel is cracked or something and needs sealant, and all other kinds of craziness. Anyway, I said no thanks and high-tailed it out of there. Not sure what happened--almost seemed like some new money hungry dentist weaseled his way into my old dentist's existing practice, somehow got all her patient details and appointments, and then tried to pull a switcheroo on everyone.

I found a new dentist for my next cleaning 6 months later and got my usual teeth look great, no problems, see you in six months. That whole experience does not foster feelings of trust toward the profession, to say the least.
